GENERAL DESCRIPTION
The M627XXML/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
microprocessor.
It also has extensive applications including battery checking,
level detecting and waveform shaping circuits.
PIN CONFIGURATION (TOP VIEW) ex. M62724
This product is on during the development, and there
is a case rescheduling it future technical standard.

• 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 ………… 1.5V to 7.0V
• Sudden change in power supply has minimal effect on the ICs
• Extra small 3-pin package (3-pin FLAT)
• 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
