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 R_L=22kΩ
• Wide supply voltage range 1.5V to 7.0V
• 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 1.5V to 7.0V
