M51953A,B/M51954A,B Voltage Detecting, System Resetting IC Series REJ03D0776-0300 Rev.3.00 Sep 18, 2007 Description M51953A,B/M51954A,B are semiconductor integrated circuits designed for detecting supply voltage and resetting all types of logic circuits such as CPUs. They include a built-in delay circuit to provide the desired retardation time simply by adding an external capacitor. They fined extensive applications, including battery checking circuit, level detecting circuit and waveform shaping circuit. 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...
