Overview
Description
REAR56953A,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.
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 ≈ 100ms, at 0.33μF)
- Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage): 0.6V (Typ.) at RL = 22kΩ
- Wide supply voltage range: 2V to 17V
- Wide application range
