M51943AGP
VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES
This product is under the development, therefore the
DESCRIPTION
technical specifications may be changed in the future.
M51943A are semiconductor integrated circuits designed for
detecting supply voltage and resetting all types of logic circuits PIN CONFIGURATION (TOP VIEW)
such as CPUs.
They find extensive applications,including battery checking
circuits, level detecting circuit and waveform shaping circuit.
FEATURES
• Few external parts
• Detecting Voltage ………4.25V typ. (4.05V to 4.45V)
GND 1
5 OUTPUT
• Low threshold operating voltage (Supply voltage to keep
low-state at low supply voltage) …0.6V(TYP.) at RL=22kΩ
• Wide supply voltage range ………… 2 to 17V
• Sudden change in power supply has minimal effect on the ICs
• Wide application range
