M51957A,B/M51958A,B Voltage Detecting, System Resetting IC Series REJ03D0778-0300 Rev.3.00 Sep 18, 2007 Description M51957A,B/M51958A,B are semiconductor integrated circuits for resetting of all types of logic circuits such as CPUs, and has the feature of setting the detection voltage by adding external resistance. 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) (M51957, M51958) • Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage): 0.
