.

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..

* 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 r.
