General 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.
Key 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 low-state at low supply voltage): 0.6 V (Typ) at RL = 22 kΩ.
- Wide supply voltage range: 2 V to 17 V.
- Wide.
