REAR56957BG Overview
Description
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.
Key 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
