描述
REAR56957A,B are semiconductor integrated circuits for resetting of all types of logic circuit such as CPUs, and have 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.
特性
- 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
