M51957B Overview
Key Specifications
Package: SIP
Mount Type: Through Hole
Pins: 5
Operating Voltage: 5 V
Description
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. 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) (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 range
