M51981ML / SL
VOLTAGE DETECTING, SYSTEM RESETTING IC SERIES
DESCRIPTION
M51981 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.
• 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
