VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES
GENERAL DESCRIPTION
The M62704ML/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
• Few external components
• Low operating threshold voltage (A supply voltage to keep a
output low-state 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 generator
• Switching circuit to a back-up power supply
• DC/DC converter
• Over voltage protection circuit

Note 1.
This IC can be used whether a pull-up resistor is included in the logic circuit or not.
Note 2.
The logic circuit preferably should not have a pull-down resistor, but in case it has, the
load resistor RL of much less than the pull-down resistor must be connected (refer to
the application circuit).
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.
