M51958A

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): 0.6 V (Typ) at RL = 22 kΩ Wide supply voltage range: 2 V to 17 V Wide application range Application Reset circuit of Pch, Nch, CMOS, microcomputer, CPU and MCU, Reset of logic circuit, Battery c...
