M62782GP
Voltage Detecting, System Resetting IC Series
REJ03D0524–0100
Rev.1.00
May 27, 2005
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)
• Wide supply voltage range
1.5V to 7.0V
• Wide application range
• Extra small 5-pin package (5-pin SOP) SOT-25
• Built-in long delay time
100ms
0.65V (Typ.) at RL=22kΩ
