Product Description

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. A separate line/switcher sense input is available to provide early warning of line or other power source failures.
FEATURES
• 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 Power OK Conditions
• 8-V to 40-V Supply Operation with 7-mA Stand-By Current
