DESCRIPTION
M51943A are semiconductor integrated circuits designed for
detecting supply voltage and resetting all types of logic circuits
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)
Low threshold operating voltage (Supply voltage to keep
low-state at low supply voltage)
…
