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 R
L
=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.

Note 1.
The logic circuit preferably should not have a pull-down resistor,but if one is present,
add load resistor R
L
to overcome the pull-down resistor.
