VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES

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.

FEATURES

• Detecting Voltage M627X2,M627X3 …… 2.87V
M627X4,M627X5 …… 2.58V
M627X6,M627X7 …… 2.39V
M627X8,M627X9 …… 1.72V

• Hysterisis Voltage ………………………… 80mV

• Delay Time M6270X ………… 0sec
M6271X ………… 200 µsec
M6272X ………… 50msec
M6273X ………… 100msec
M6274X ………… 200msec

• 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

This product is on during the development, and there
is a case rescheduling it future technical standard.
