MITSUBISHI STD-LINEAR
M62720GP
VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES
GENERAL DESCRIPTION
The M62720GP 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 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
