General Description

The G690/G691 are microprocessor (µP) supervisory

circuits used to monitor the power supplies in µP and

digital systems. They provide excellent circuit reliability

and low cost by eliminating external components and

adjustments when used with +5V, +3.3V, +3.0V- pow-

ered circuits.

These circuits perform a single function: they assert a

reset signal whenever the VCC supply voltage declines

below a preset threshold, keeping it asserted for at

least 140ms after VCC has risen above the reset

threshold. Reset thresholds suitable for operation with

a variety of supply voltages are available.

The G691L has an open-drain output stage, while the

G690 have push-pull outputs. The G691L’s open-drain

RESET output requires a pull-up resistor that can be

connected to a voltage higher than VCC. The G690L

have an active-low RESET output, while the G690H

has an active-high RESET output. The reset com-

parator is designed to ignore fast transients on VCC,

and the outputs are guaranteed to be in the correct

logic state for VCC down to 1V.

Low supply current makes the G690/G691 ideal for

use in portable equipment. The G690/G691 are avail-

able in 3-pin SOT89 or SOT23 or SC70 packages.

Pin Description

PIN NAME FUNCTION

1 GND Ground

(G691L/G690L)

RESET Output remains low while VCC is below the reset threshold, and for at least 140ms after

VCC rises above the reset threshold.

2 RESET

(G690H)

RESET Output remains high while VCC is below the reset threshold, and for at least 140ms after

VCC rises above the reset threshold.

3 VCC Supply Voltage (+5V, +3.3V, +3.0V)

Detailed Description

A microprocessor’s (µP’s) reset input starts the µP in a

known state. The G691L/G690L/G690H assert reset to

prevent code-execution errors during power-up,

power-down, or brownout conditions. They assert a

reset signal whenever the VCC supply voltage declines

below a preset threshold, keeping it asserted for at

least 140ms after VCC has risen above the reset

threshold. The G691L uses an open-drain output, and

the G690L/G690H have a push-pull output stage.

Connect a pull-up resistor on the G691L’s RESET out-

put to any supply between 0 and 5.5V.

Figure 1. Maximum Transient Duration Without

Causing a Reset Pulse vs. Reset Com-

parator Overdrive

Figure2. RESET Valid to VCC = Ground Circuit

Applications Information

Negative-Going VCC Transients

In addition to issuing a reset to the µP during

power-up, power-down, and brownout conditions, the

G691L/G690H/G690L are relatively immune to short-

duration negative-going VCC transients (glitches).

Figure 1 shows typical transient duration vs. reset

comparator overdrive, for which the G691L/G690H/

G690L do not generate a reset pulse. The graph was

generated using a negative-going pulse applied to VCC,

starting 0.5V above the actual reset threshold and

ending below it by the magnitude indicated (reset

comparator overdrive). The graph indicates the maxi-

mum pulse width a negative-going VCC transient can

have without causing a reset pulse. As the magnitude

of the transient increases (goes farther below the reset

threshold), the maximum allowable pulse width de-

creases. Typically, for the G69_ _463 and G69_ _438,

a VCC transient that goes 100mV below the reset

threshold and lasts 7µs or less will not cause a reset

pulse. A 0.1µF bypass capacitor mounted as close as

possible to the VCC pin provides additional transient

immunity.

Ensuring a Valid Reset Output Down to VCC = 0

When VCC falls below 1V, the G690 RESET output

no longer sinks current—it becomes an open circuit.

Therefore, high-impedance CMOS logic inputs con-

nected to RESET can drift to undetermined voltages.

This presents no problem in most applications since

most µP and other circuitry is inoperative with VCC

below 1V. However, in applications where RESET

must be valid down to 0V, adding a pull-down resistor

to RESET causes any stray leakage currents to flow

to ground, holding RESET low (Figure 2). R1’s value

is not critical; 100kΩ is large enough not to load

RESET and small enough to pull RESET to ground.

A 100kΩ pull-up resistor to VCC is also recommended

for the G691L if RESET is required to remain valid

for VCC < 1V.

Interfacing to µPs with Bidirectional Reset Pins

Since the RESET output on the G691L is open drain,

this device interfaces easily with µPs that have bidi-

rectional reset pins, such as the Motorola 68HC11.

Connecting the µP supervisor’s RESET output di-

rectly to the microcontroller’s (µC’s) RESET pin with

a single pull-up resistor allows either device to assert

reset (Figure 3).

G691L Open-Drain RESET Output Allows Use with

Multiple Supplies

Generally, the pull-up connected to the G691L will

connect to the supply voltage that is being monitored

at the IC’s VCC pin. However, some systems may use

the open-drain output to level-shift from the monitored

supply to reset circuitry powered by some other supply

(Figure 4). Note that as the G691L’s VCC decreases

below 1V, so does the IC’s ability to sink current at

RESET . Also, with any pull-up, RESET will be pulled

high as VCC decays toward 0. The voltage where this

occurs depends on the pull-up resistor value and the

voltage to which it is connected.

Benefits of Highly Accurate Reset Threshold

Most µP supervisor ICs have reset threshold voltages

between 5% and 10% below the value of nominal

supply voltages. This ensures a reset will not occur

within 5% of the nominal supply, but will occur when

the supply is 10% below nominal.

When using ICs rated at only the nominal supply ±5%,

this leaves a zone of uncertainty where the supply is

between 5% and 10% low, and where the reset may or

may not be asserted.

The G69_ _463/G69_ _308 use highly accurate circuitry

to ensure that reset is asserted close to the 5% limit,

and long before the supply has declined to 10% below

nominal.
