- VOLTAGE DETECTING, SYSTEM RESETTING IC
- Features
- Few external parts
- Large delay time with a capacitor of small capacitance (td 100ms, at 0.33uF)
- (M51957, M51958)
- Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage)
- Wide supply voltage range ............. 2 - 17V
- Sudden change in power supply has minimal effect on the ICs
- Wide operation range of detecting input pin .. Narrower ranges of 0.3V - VCC or 0.3V - 7v (Input voltage detecting type)
- Suitable for high supply voltage circuit with simple circuit structure (M51957B, M51958B)
- Permits easy configuration of circuit for protection against reverse cnnection or surges. (M51957B, M51958B)
