General Description
The UC1903 family of quad supply and line monitor integrated circuits will respond to under- and over-voltage conditions on up to four continuously monitored voltage levels.
An internal op-amp inverter allows at least one of these levels to be negative.
Key Features
- 1.
- Inputs for Monitoring up to Four Separate Supply Voltage Levels.
- Internal Inverter for Sensing a Negative Supply Voltage.
- Line/Switch Sense Input for Early Power Source Failure Warning.
- Programmable Under- and Over-Voltage Fault Thresholds with Proportional Hysteresis.
- A Precision 2.5-V Reference.
- General Purpose Op-Amp for Auxiliary Use.
- Three High Current, >3 0mA, Open-Collector Outputs Indicate Over-Voltage, Under-Voltage and P.
