G690/G691

Microprocessor Reset IC

Features

Precision Monitoring of +3V, +3.3V, and +5V

Power-Supply Voltages

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 V

supply voltage declines

below a preset threshold, keeping it asserted for at

least 140ms after V

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 V

. 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 V

and the outputs are guaranteed to be in the correct

logic state for V

down to 1V.

Fully Specified Over Temperature

Low supply current makes the G690/G691 ideal for

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

able in 3-pin SOT-23 packages.
