GENERAL DESCRIPTION The M62702ML/SL 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 a microcontroller. It has extensive applications including battery checking, level detecting and waveform shaping circuits. FEATURES • Few external components • Low operating threshold voltage (Supply voltage to keep a output low in a low supply operation) …0.65V(typ) at RL=22kΩ • Wide supply voltage range ………… 2V to 7V • High immunity to a sudden supply voltage change • Wide application range • Extra small 3-pin package (3-pin FLAT) APPLICATION • Rest pulse generation for almost all logic circuits • Battery checking, level detecting, waveform shaping circuits • Switching circuit for a back-up power supply • DC-DC converter • Over voltage protection circuit RECOMMENDED OPERATING CONDITION • Supply voltage range ………… 2V to 7V

Note 1. This IC can be used whether or not a pull-up resistor is included in the logic circuit. Note 2. The logic circuit preferably should not have a pull-down resistor. However in the case it has, the load resistor RL must be much less than the pull-down resistor. (refer to the above application circuit)
