VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES
M62707ML
GENERAL DESCRIPTION
The M62703ML/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
microcontroller.
It has extensive applications including battery checking, level
detecting and waveform shaping circuits.
FEATURES
• Few external components
• Low operating threshold voltage (Supply voltage to keep a
output low in a low supply operation)
…
0.65V(typ) at R
L
= 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 generating circuit
• Switching circuit to a back-up power supply
• DC/DC converter
• Over voltage protection circuit
RECOMMENDED OPERATING CONDITION
• Supply voltage range
…………
2V to 7V

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