NEW P UC D O R T MITSUBISHI M62782GP VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES GENERAL DESCRIPTION The M62782GP 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=22kΩ Wide supply voltage range ………1.5to 7.0V Sudden change in power supply has minimal effect on the ICs Wide application range Extra small 5-pin package (5-pin SOP) …SOT-25 Built-in long delay time ………… 100 ms 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 PIN CONFIGURATION (TOP VIEW) GND SUB (GND) 2 3 M62782GP 1 5 OUTPUT N.C. 4 SUPPLY VOLTAGE Outline SOT-25 N.C. :NO CONNECTION BLOCK DIAGRAM M62782GP SUPPLY VOLTAGE 4 R1 R2 OSC COUNTER 5 OUTPUT + 1.25V 3 N.C. 2 SUB (GND) 1 GND N.C. :NO CONNECTION ( 1 / 4 ) 1999-9-14 MITSUBISHI M62782GP VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES FUNCTION D...
