G696/G697

Microprocessor Reset IC

Features

General Description

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

Power-Supply Voltages

The G696/G697 are microprocessor (µP) supervisory

circuits used to monitor the power supplies in µP and

digital systems. They provide excellent circuit reliability

and low cost and adjustments when used with +5V,

+3.3V, +3.0V- powered circuits.

Fully Specified Over Temperature

Available in Three Output Configurations

Push-Pull RESET Output (G696L)

Push-Pull RESET Output (G696H)

These circuits perform a single function: they assert a

reset signal whenever the V_CCsupply voltage declines

below a preset threshold, with hysteresis keeping it

asserted for time delay determined by externally pro-

grammable time delay generator after V_CChas risen

above the reset threshold. Reset thresholds suitable

for operation with a variety of supply voltages are

available.

Open-Drain RESET Output (G697L)

Externally Programmable Time Delay Generator

14µA Supply Current

Guaranteed Reset Valid to V_CC= 0.8V

Power Supply Transient Immunity

5 pin SOT23-5 Packages

2% Threshold Accuracy

The G697L has an open-drain output stage, while the

G696 have push-pull outputs. The G697L’s open-drain

Applications

Computers

RESET output requires a pull-up resistor that can be

connected to a voltage higher than V_CC. The G696L

Controllers

Intelligent Instruments

Critical µP and µC Power Monitoring

Portable / Battery-Powered Equipment

Automotive

have an active-low RESET output, while the G696H

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 0.8V.

Low supply current makes the G696/G697 ideal for

use in portable equipment. The G696/G697 are avail-

able in 5-pin SOT23-5 packages.
