■FUNCTIONAL DESCRIPTION

1. Power Supply Control Unit

(1) Reference Voltage Block

The ref erence voltage circuit uses the v oltage supplied from the VCC terminal (pin 40) and generates a temper-

ature compensated reference voltage (1.23 V (typ.)), for use as the reference voltage for the power supply control

unit.

(2) Constant Voltage Control Block (REG1)

This constant v oltage control bloc k (REG1) uses the v oltage supplied from the ref erence v oltage and generates

the output voltage (2.5 V) from the OUT1 terminal (pin 29).

An external load current can be obtained from the OUT1 terminal up to a maximum of 70 mA.

Also, by setting the ICONT terminal (pin 36) to “L” level the MB3893 can be placed in low current consumption

(standby) mode . In standb y mode , REG1 is On with a maximum output load of 500 µA, and REG3 is Off . In this

state, ripple rejection and noise levels are not assured.

(3) Constant Voltage Control Block (REG2)

This constant v oltage control bloc k (REG2) uses the v oltage supplied from the ref erence v oltage and generates

the output voltage (1.8 V) from the OUT2 terminal (pin 30).

An external load current can be obtained from the OUT2 terminal up to a maximum of 50 mA.

Also, by setting the ICONT terminal (pin 36) to “L” level the MB3893 can be placed in low current consumption

(standby) mode . In standb y mode , REG2 is On with a maximum output load of 500 µA, and REG3 is Off . In this

state, ripple rejection and noise levels are not assured.

(4) Constant Voltage Control Block (REG3)

This constant v oltage control bloc k (REG3) uses the v oltage supplied from the ref erence v oltage and generates

the output voltage from the OUT3 terminal (pin 27).

An external load current can be obtained from the OUT3 terminal up to a maximum of 70 mA.

Also, the output voltage can be changed to 1.9V or 2.2 V by mask option.

(5) Constant Voltage Control Block (REG4)

This constant v oltage control bloc k (REG4) uses the v oltage supplied from the ref erence v oltage and generates

the output voltage (2.5 V) from the OUT4 terminal (pin 22).

An external load current can be obtained from the OUT4 terminal up to a maximum of 60 mA.

Also, by setting the ICONT terminal (pin 36) to “L” level the MB3893 can be placed in low current consumption

(standby) mode . In standb y mode , REG4 is On with a maximum output load of 500 µA, and REG3 is Off . In this

state, ripple rejection and noise levels are not assured.

(6) VREF1M

This block takes the reference voltage (1.23 V (typ.)) generated by the reference voltage block, and uses a

voltage follower to produce a temperature compensated reference voltage (1.23 V (typ.)) at the VREF1M terminal

(pin 10).

Also, an external load current can be obtained from the VREF1M terminal up to a maximum of 1 mA.

(7) ON/OFF Control Block

This block controls regulator On/Off switching according to the voltage levels of the POFF terminal (pin 18),

CONT2 terminal (pin 26), CONT5 terminal (pin 6), ICONT terminal (pin 36), DRST terminal (pin 5), XON terminal

(pin 11), ONOFF1 terminal (pin 9), ONOFF2 terminal (pin 17), and CONT1 terminal (pin 14).

MB3893

(8) POR Block

When the output voltage from the regulator (OUT1) exceeds 2.3 V (typ.), the XRST ter minal (pin 35) goes to

“H” level f ollowing a dela y time (85 ms (typ.)) set by capacitors (0.1 µF (typ.)) connected between the C1 terminal

(pin 7) and the GND1 terminal (pin 8) and GND2 terminal (pin 39). Also, when the regulator (OUT1) output

voltage falls below 2.2 V ((typ.)), the XRST terminal goes back to “L” level.

(9) Initial Power Supply Drop Detection 1

This bloc k controls MB3893 oper ation when VCC startup occurs at VCC voltage of 2.0V (typ .) or g reater. When

VCC voltage exceeds 2.75V (typ.) the VCONT terminal (pin 16) voltage goes to “H” level, and the regulated

voltage is output from the OUT1 terminal (pin 29), OUT2 ter minal (pin 30), and OUT4 terminal (pin 22). When

VCC voltage falls below 3.1V (typ.), the voltage at the OUT1, OUT2, and OUT4 terminals is outside of rated

values. Then when VCC voltage fa lls below 2.5V (typ.), the VCONT terminal (pin 16) voltage goes to “L” level,

and the OUT1, OUT2, and OUT4 ter minals go to “L” level (regulator “OFF” state). Hereafter this is referred to

as “L” level. As long as the VCC voltage rises again before dropping below 2.0V (typ.), the VCONT pin voltage

will return to “H” le vel once VCC reaches 3.5 V (typ .), and the regulated v oltage is output from the OUT1, OUT2,

and OUT4 terminals.

(10) Transient Power Supply Drop Detection 2

This block detects two types of power supply drop times according to the time constants CR1 and CR2, and

produces the related output at the VBDET1 terminal (pin 34) and VBDET2 terminal (pin 33).

2. Charge Control Block

The charge control block checks VIN, battery voltage, and battery temperature before charging. If the results

are within nor mal ranges, charging begins. During charging, the charging times and current levels are var ied

according to battery voltage . The VIN and battery temperature are monitored, and if either e xceeds the normal

range charging is stopped. Conditions are then monitored f or a fixed time (16 min (typ .)) and a resume charging/

abnormal termination determination is made.

The MB3893 also provides an o vercharge protection function, as well as a function that stops charging when a

rise in IC junction temperature is detected.

Once charging has stopped due to any of these abnormal conditions, it can be resumed by re-input of VIN, or

by removing and replacing the battery.

(1) Constant Current/Constant Voltage Charging

The MB3893 applies a constant current charge according to the battery voltage level, selecting o ver discharge

recover y charging (2.1 mA (typ.)), preliminary charging (80 mA (typ.)) or rapid charging (590 mA (typ.)). Once

batter y voltage reaches 4.1 V (4.2 V), constant voltage charging is applied until the charge current falls to 53

mA (typ.) at constant voltage.

(2) Timer Function

The timer switches the charging time according to the batter y voltage level, between over discharge recover y

charging (15 s (typ.)), preliminary charging (16 min (typ.)), and rapid charging (240 min (typ.)).

(3) Temperature/AC Adapter Voltage Detection

This bloc k detects the battery temperature and A C adapter v oltage, and stops charging if either is outside of the

normal charging range . If normal conditions are restored within a set time (16 min (typ .)), charging is resumed,

otherwise an abnormal termination is determined.

(4) Over-Charge Protection

If battery voltage exceeds 4.3 V (typ.) this block determines an abnormal condition, and stops charging.

■SETTING THE XON DELAY TIME

When the XON ter minal (pin 11) voltage changes from “H” to “L” level, the VCONT signal (pin 16) rises. The

time constant of the capacitor (CRC1) and resistor (RRC1) connected to the RC1 ter minal (pin 15) determine the

delay time before the rise of the VCONT signal (pin 16).

XON delay time : TXON (ms) := 598.3 × CRC1 (µF)

■

■■

■SETTING THE XRST DELAY TIME

The time constant of the capacitor (CC1) connected to the C1 terminal (pin 7) determines the dela y time between

the rise of the OUT1 terminal (pin 29) voltage above 2.3 V (typ.) and the rise of the XRST terminal (pin 35) voltage.

■

■■

■SETTING THE POWER SUPPLY DROP DETECTION TIME

When the VCC terminal (pin 40) v oltage fa lls below 2.0 V (typ .) the CR1 terminal (pin 12) and CR2 terminal (pin

13) are opened, and the capacitors (CCR1, CCR2) connected to the CR1 and CR2 terminals are discharged through

the respective resistors (RCR1, RCR2). The discharge time (cutoff detection time) of the CR1 and CR2 pins can

be set according to the time constants of the capacitors and resistors connected to the CR1 and CR2 terminals

respectively, between 0.89 V (typ.) to 0.51 V (typ.).

Cutoff detection time : Tdet1 (s) := −CCR1 (µF) × RCR1 (MΩ) × ln (0.51 (V) /0.89 (V) )

Tdet2 (s) := −CCR2 (µF) × RCR2 (MΩ) × ln (0.51 (V) /0.89 (V) )

■BATTERY TEMPERATURE DETECTION

The battery temperature sensor uses the thermistor shown below. The thermistor temperature coefficient is set

by the following formula.

■SETTING THE OSCILLATOR PERIOD

The oscillator period is set by connecting a timing capacitor (COSC) to the COSC terminal (pin 44), and a timing

resistor (ROSC) to the ROSC terminal (pin 45).

Oscillator period : TOSC (µs) := 1.073 × 10−3 × {COSC (pF) + CP (pF) } × ROSC (kΩ)

CP : Board capacitor := 19 (pF)

■SETTING THE OVER DISCHARGE RECOVERY CHARGE TIME

When battery voltage is less than the preliminary charge start voltage (2.115 V (typ.)), the over discharge recovery

charge time is set by the following formula.

Over discharge recovery charge time : Treco (s) := TOSC (s) × 221

■

■■

■PRELIMINARY CHARGE TIME

When battery voltage is higher than the preliminary charge start voltage (2.115 V (typ.)), and lower than the fast

charge start voltage (3.115 V (typ.)), the preliminary charge time is set by the following formula.

■

■■

■RAPID CHARGE TIME

When battery voltage is higher then the fast charge start voltage (2.115 V (typ.)), and lower than the overvoltage

stop voltage (4.325 V (typ.)), the rapid charging time is determined by the following formula.

Preliminary charge time : Tpc (min) := TOSC (s) × 227

Rapid charging time : Tft (min) := TOSC (s) × (227 + 228 + 229 + 230)

■POWER SUPPLY CONTROL UNIT TIMING CHART

1. Power Supply Drop Detection 1

As Figure 1 shows, there is a “don’t care zone” where VCC voltage is below 2 V. When VCC voltage is above

VCCE voltage (2.75 V (typ.)), the VCONT ter minal (pin 16) goes to “H” level, and after a delay time (TR) the

OUT1 terminal (pin 29), the OUT2 terminal (pin 30), and the OUT4 terminal (pin 22) output their regulated

voltages. When VCC voltage falls below VCCD voltage (2.50 V (typ.)), a power supply drop detection is deter-

mined and the VCONT terminal goes to “L” le vel, and theref ore the OUT1, OUT2, and OUT4 terminals also go

to “L” level. If the VCC voltage r ises again before falling below 2 V, the OUT1, OUT2, and OUT4 ter minals will

once again output their regulated voltages once VCC exceeds the VCCR voltage (3.50 V (typ.))

2. Delayed ON Input Operation (XON)

As Figure 2 shows, When the XON terminal (pin 11) changes from “H” to “L” level, the capacitor connected to

the RC1 terminal (pin 15) starts to charge. After the dela y interval (TXON : 600ms (typ.)), once the RC1 terminal

exceeds the inter nal threshold voltage the VCONT terminal (pin 16) goes to “H” level, and the OUT1 (pin 29),

OUT2 (pin 30), OUT3 (pin 27), and OUT4 (pin 22) terminals then output their respective regulated voltages after

a dela y interval (TR1). Note how ev er that f or the OUT3 terminal to output its regulated voltage , it is necessary for

the CONT2 terminal (pin 26) to be at “L” le vel. Also, fo r the XON pin to return from “L” level to “H” le vel, a dela y

interval (TXON : 600 ms (typ.)) is required.

3. CONT1 Input Operation

As Figure 3 shows, when the CONT1 terminal (pin 14) goes from “H” to “L” level, the VCONT terminal (pin 16)

goes to “H” level, and the OUT1 (pin 29), OUT2 (pin 30), OUT3 (pin 27), and OUT4 (pin 22) terminals then output

their respectiv e regulated voltages after a dela y interval (TR1). Note how ev er that for the OUT3 terminal to output

its regulated voltage, it is necessar y for the CONT2 terminal (pin 26) to be at “L” level. Also once the OUT1,

OUT2, OUT3, and OUT4 terminals have star ted to output their regulated voltages, the voltage at the OUT1,

OUT2, OUT3, and OUT4 terminals will not change even if the CONT1 terminal goes from “L” to “H” level, or

from “H” level to “L” level.

22) terminals then after a dela y interval (t) go to “L” level. Also, a minimum of 10 µs is required to set the POFF

signal to “H” level.

5.CONT2 Input Operation

As Figure 5 shows, when the CONT2 ter minal (pin 26) goes from “H” to “L” level, the OUT3 ter minal (pin 27)

after a delay inter val (TR1) outputs its regulated voltage. When the CONT2 ter minal goes from “L” to “H” level,

then the OUT3 terminal returns to “L” level after the required fall time (t).

As Figure 6 shows , when the ONOFF1 terminal (pin 9) goes from “L” le vel to “H” le v el, the VCONT terminal (pin

16) goes to “H” le vel, and the OUT1 (pin 29), OUT2 (pin 30), OUT3 (pin 27), and OUT4 (pin 22) terminals output

their respective regulated voltages.

The next time the POFF terminal (pin 18) goes from “L” level to “H” level, the VCONT terminal (pin 16) goes to

“L” level, and the OUT1 (pin 29), OUT2 (pin 30), and OUT4 (pin 22) terminals go to “L” level. Then when the

ONOFF2 terminal (pin 17) goes from “L” level to “H” level, the VCONT terminal returns to “H” level, and the

OUT1, OUT2, OUT3 and OUT4 terminals output their respective regulated voltages.

The ne xt time the POFF terminal goes from “L” level to “H” le vel, the VCONT terminal goes to “L” level, and the

OUT1, OUT2, and OUT4 ter minals go to “L” level. Then when the ONOFF1 terminal goes from “L” level to “H”

le vel, the VCONT terminal returns to “H” le vel, and the OUT1, OUT2 and OUT4 terminals output their respective

regulated voltages.

The ne xt time the POFF terminal goes from “L” level to “H” le vel, the VCONT terminal goes to “L” level, and the

OUT1, OUT2, and OUT4 ter minals go to “L” level. Then when the ONOFF2 terminal goes from “H” level to “L”

le vel, the VCONT terminal returns to “H” le vel, and the OUT1, OUT2 and OUT4 terminals output their respective

regulated voltages.

The ne xt time the POFF terminal goes from “L” level to “H” le vel, the VCONT terminal goes to “L” level, and the

As Figure 8 shows, when the VCONT terminal (pin 16) goes from “L” level to “H” leve l, the OUT1 terminal (pin

29) outputs its regulated vo ltage. Then, after a delay interval (85 ms (typ.)) the XRST terminal (pin 35) goes to

“H” level.

If after the XRST terminal has gone to “H” le v el the ICONT terminal (pin 36) goes to “L” le v el, the MB3893 goes

into standby mode , reducing the IC internal current consumption. When the ICONT terminal returns to “H” lev el

normal operation is restored.

When the VCONT terminal goes from “H” le vel to “L” le vel, the OUT1 terminal goes to “L” le vel. At this time the

XRST terminal also goes to “L” level.

9. Power Supply Drop Detector 2 (Initial power supply detector/power supply drop detector)

a) t > 10 s

The MB3893 pow er supply drop detection intervals are set to Tdet1 (10 s (typ.)) and Tdet2 (1.5 s (typ.)) so that,

as shown in Figure 9(a), when VCC goes from “H” level to “L” level, the OUT1 (pin 29), OUT2 (pin 30), and

OUT4 (pin 22) ter minals go to “L” level, and the XRST ter minal (pin 35) also goes to “L” level. At this time, the

VBDET1 terminal (pin 34) and VBDET2 terminal (pin 33) also go to “L” level. When VCC drops for a fixed interval

(t > 10 s), and then returns to “H” le v el, the OUT1, OUT2, and OUT4 terminals after a dela y interval (TR2) output

their regulated voltages, and the XRST terminal after a delay interval (Tpor) goes to “H” le vel. During the interval

between the VCC drop and XRST terminal return to “H” level the VBDET1 ter m inal and VBDET2 terminal are

in undefined state. Also once the XRST terminal returns to “H” level the VBDET1 terminal is at “L” le v el and the

VBDET2 terminal is at “H” le vel. At this time , if the DRST terminal (pin 5) goes to “H” lev el, the VBDET1 terminal

also goes to “H” level. Note that the DRST terminal must be at “H” level for at least an interval of 10 µs.

OUT4 (pin 22) ter minals go to “L” level, and the XRST ter minal (pin 35) also goes to “L” level. At this time, the

■ABOUT CAPACITOR CONNECTED TO VCC PIN

When the VCC v oltage exceeds 2.75 V (typ .), the VCONT terminal (pin 16) goes to “H” lev el, and the OUT1 (pin

29), OUT2 (pin 30), and OUT4 (pin 22) ter minals rise. When each of these respective OUT terminals rises, a

rush current flows to the capacitor connected to that OUT ter minal. At this time the inter nal impedance of the

batter y causes VCC to drop, and if VCC vo ltage goes below 2.5 V (typ.), the OUT terminal voltage regurn s to

“L” le vel (regulator OFF mode).t is necessary to set the capacitor connected between VCC and GND taking into

■USAGE PRECAUTIONS

1. Never use settings exceeding maximum rated conditions.

Exceeding maximum rated conditions may cause permanent damage to the LSI.

Also, it is recommended that recommended operating conditions be observed in normal use.

Exceeding recommended operating conditions may adversely affect LSI reliability.

2. Use this device within recommended operating conditions.

Recommended operating conditions are v alues within which normal LSI operation is warranted. Standard elec-

trical characteristics are warranted within the range of recommended oper ating conditions and within the listed

conditions for each parameter.

3. Printed circuit board ground lines should be set up with consideration for common imped-

ance.

4. Take appropriate static electricity measures.

• Containers f or semiconductor materials should ha ve anti-static protection or be made of conductive material.

• After mounting, printed circuit boards should be stored and shipped in conductive bags or containers.

• Work platforms, tools, and instruments should be properly grounded.

• Working personal should be grounded with resistance of 250 kΩ to 1 MΩ between body and ground.

5. Do not apply negative voltages.

The use of negative voltages below –0.3 V may create parasitic transistors on LSI lines, which can cause

abnormal operation.
