DETECTING, SYSTEM RESETTING IC SERIES
GENERAL DESCRIPTION
The M62703ML/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
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
• Reset pulse generation for almost all logic circuits
• Battery checking, level detecting, waveform shaping circuits
• Delayed waveform generating circuit
• Switching circuit to a back-up power supply
• DC/DC converter
• Over voltage protection circuit
RECOMMENDED OPERATING CONDITION
• Supply voltage range ………… 2V to 7V
