GENERAL DESCRIPTION

The M62781GP is a voltage threshold detector designed for detection of a supply voltage and generation of a system reset pulse for almost all logic circuits such as microprocessor.

It also has extensive applications including battery checking, level detecting and waveform shaping circuits.

FEATURES

• Few external parts

• Low threshold operating voltage (Supply voltage to keep

low-state at low supply voltage) …0.65V(TYP.) at RL=22kW

• Wide supply voltage range ………… 1.5to 7.0V

• Sudden change in power supply has minimal effect on the ICs

• Wide application range

• Extra small 3-pin package (3-pin SOP)

• Built-in long delay time

APPLICATION

• Reset pulse generation for almost all logic circuits

• Battery checking, level detecting, waveform shaping circuits

• Delayed waveform generator

• Switching circuit to a back-up power supply

• DC/DC converter

• Over voltage protection circuit

RECOMMENDED OPERATING CONDITION

• Supply voltage range ………… 1.5to 7.0V
