G632

Global Mixed-mode Technology

4-Pin µP Voltage Monitors with Manual Reset Input

Features

General Description

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

Power-Supply Voltages

The G632 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 ad-

justments when used with +5V, +3.3V, +3.0V- powered

circuits. The G632 also provides a debounced manual

reset input.

Fully Specified Over Temperature

Push-Pull Active-low RESET Output

220ms Min Power-On Reset Pulse Width

10µA Supply Current

Guaranteed Reset Valid to V_CC= +1V

Power Supply Transient Immunity

No External Components

Manual Reset Input

SOT-143 Package

2% Threshold Accuracy

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 220ms after V_CChas risen above the reset

threshold. Reset thresholds suitable for operation with

a variety of supply voltages are available.

Applications

The G632 have a push-pull and active-low RESET

output. The reset comparator 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.

Critical µP and µC Power Monitoring

Portable / Battery-Powered Equipment

Automotive

Low supply current makes the G632 ideal for use in

portable equipment. The G632 are available in a

SOT-143 packages.

ICC may increased at high T_A, Therefore, can not connect

Resistors to VCC to prevent Icc abnormal behavior at high T_A.
