Description
M51953A,B/M51954A,B Voltage Detecting, System Resetting IC Series REJ03D0776-0300 Rev.3.00 Sep 18, 2007 .
M51953A,B/M51954A,B are semiconductor integrated circuits designed for detecting supply voltage and resetting all types of logic circuits such as CPUs.
Features
* Few external parts
* Large delay time with a capacitor of small capacitance (td ≈ 100 ms, at 0.33 µF) (M51953, M51954)
* Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage):
0.6 V (Typ) at RL = 22 kΩ
* Wide supply voltage range:
