DESCRIPTION
The monolithic integrated circuits contain all the functions necessary to monitor and control the output of a sophisticated power supply system. Over-voltage (O.V.) sensing with provision to trigger an external SCR “crowbar” shutdown; an undervoltage (U.V.) circuit which can be used to monitor either the output or to sample the input line voltage; and a third op amp/comparator usable for current sensing (C.L.) are all included in this device, together with an independent, accurate reference generator.

FEATURES
• Includes Over-Voltage, Under-Voltage, and Current Sensing Circuits
• Internal 1% Accurate Reference
• Programmable Time Delays
• SCR “Crowbar” Drive of 300 mA
• Remote Activation Capability
• Optional Over-Voltage Latch
• Uncommitted Comparator Inputs for Low Voltage Sensing (UC1544 Series Only)
