Now over 1,400 items in our Store! Please note: The following spec sheet / information is provided by the manufacturer and may cover several different items and/or products. I am offering the part listed in the heading and picture ONLY. M51957A,B/M51958A,B are semiconductor integrated circuits designed for detecting input 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. 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 k? Wide supply voltage range: 2 V to 17 V Wide operation range of detecting input pin:bNarrower ranges of –0.3 V to VCC or –0.3 V to 7 V (input voltage detecting type) Suitable for high supply voltage circuit with simple circuit structure (M51957B, M51958B) Permits easy configuration of a circuit for protection against reverse connection or surges. (M519575B, M51958B) Reset circuit of Pch, Nch, CMOS, microcomputer, CPU and MCU, Reset of logic circuit, Battery check circuit, switching circuit back-up voltage, level detecting circuit, waveform shaping circuit, delay waveform generating circuit, DC/DC converter, over voltage protection circuit Recommended Operating Condition • Supply voltage range: 2 V to 17 V for other great component bargains on Microprocessors, Transistors, Capacitors, IC's, Transformers, Diodes, Crystals, and more! And we salute our friends in other countries around the world! (this posting is the responsibility of the poster) |
