VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES
This product is on during the development, and there
is a case rescheduling it future technical standard.
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.

Note 1.
The logic circuit preferably should not have a pull-down resistor,but if one is present,
add load resistor RL to overcome the pull-down resistor.
Mitsubishi Electric Corporation puts the maximum effort into making semiconductor products better and more reliable,
but there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal
injury,fire or property damage.Remember to give due consideration to safety when making your circuit design,in order
to prevent fires from spreading,redundancy,malfunction or other mishap.
