G692/G693

4-Pin µP Voltage Monitors with Manual Reset Input

Features

General Description

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

Power-Supply Voltages

The G692/G693 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. The G692/G693 also provide a de-

bounced manual reset input.

^ꢀFully Specified Over Temperature

^ꢀAvailable in Three Output Configurations

Push-Pull RESET Output (G692L)

Push-Pull RESET Output (G692H)

Open-Drain RESET Output (G693L)

^ꢀ140ms min Power-On Reset Pulse Width

^ꢀ5µA Supply Current

These circuits perform a single function: they assert a

reset signal whenever the V_CCsupply voltage declines

below a preset threshold, keeping it asserted for at

least 140ms after V_CChas risen above the reset

threshold. Reset thresholds suitable for operation with

a variety of supply voltages are available.

^ꢀGuaranteed Reset Valid to V_CC= +1V

^ꢀPower Supply Transient Immunity

^ꢀNo External Components

^ꢀManual Reset Input

^ꢀ4-Pin SOT143 Package

The G693L has an open-drain output stage, while the

G692 have push-pull outputs. The G693L’s open-drain

Applications

RESET output requires a pull-up resistor that can be

connected to a voltage higher than V_CC. The G692L

have an active-low RESET output, while the G692H

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

parator is designed to ignore fast transients on V_CC

and the outputs are guaranteed to be in the correct

logic state for V_CCdown to 1V.

^ꢀComputers

^ꢀControllers

^ꢀIntelligent Instruments

^ꢀCritical µP and µC Power Monitoring

^ꢀPortable / Battery-Powered Equipment

^ꢀAutomotive

Low supply current makes the G692/G693 ideal for

use in portable equipment. The G692/G693 are avail-

able in a 4-pin SOT143 packages.
