■
■■
■DESCRIPTION
MB3892 is a low-saturation voltage type series regulator contains 3 channels for the baseband regulator, 1 channel
f or the back up regulator , 6 channels f or the RF regulator , and 1 channel f or the variable regulator. MB3892 is built
in reset circuit, serial control circuit, operation Amp. for charge control of Lithium ion battery, LED drive circuit,
receiver Amp., loudspeaker drive Amp., sounder circuit, vibrator drive circuit, and 4-ch D/A conver ter and the
devices is miniaturized by systematization of built-in power supply for mobile phone.
■
■■
■FEATURES
• Power supply voltage range : VB = 2.85 V to 5.5 V
: EXTVCC = 3.0 V to 6.5 V
• Low power consumption current during standby : 100 µA (Max.)
• Built-in low-saturation voltage type series regulator
• Built-in power-on reset function
• Built-in serial control function
• Built-in operation Amp. for charge control of Lithium ion battery
• Special power off function
(To prevent batter y discharge, this function controls the power consumption current of main IC under 11 µA
(typ.) on the shipment.)

■RECOMMENDED OPERATING CONDITIONS
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.

■SETTING OF HOLD TIME FOR POWER-ON RESET
According to the time constant set by capacitor (CTP) connected to CTP terminal (pin 76), rise time (hold time)
of RESET terminal (pin 77) voltage can be set after OUT1 terminal (pin 75) voltage exceeds 2.75V (typ.).
(1) When the OUT1 terminal (pin 75) voltage exceeds detected rising voltage (2.75V typ.), the charge for
timing capacitor (CTP) for hold time for power-on reset starts .
(2) When the CTP terminal (pin 76) voltage exceeds 1.23V (typ.), the reset is canceled. (The RESET ter-
minal voltage becomes "H" level from "L" level.: rising time from 10% to 90% = tr)
(3) When OUT1 terminal voltage falls below detected rising voltage (2.685V typ.), the CTP terminal voltage
is down and the reset signal is output. (RESET terminal voltage becomes "L" level from "H" level.)
(4) When OUT1 terminal voltage exceeds rising voltage detect, charging of CTP is started.
(5) When CTP terminal voltage rises above threshold voltage, the reset is canceled.
(6) When OUT1 terminal voltage falls below the voltage detect, the reset signal is output.

■USAGE PRECAUTIONS
• Printed cir cuit boar d ground lines should be set up with consideration f or common impedance.
• 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.
•Do not apply negative voltages
The use of negative voltages below -0.3V may create parasitic transistors on LSI lines, Which can cause abnormal
operation.
