SG2543
Overview
This monolithic integrated circuit contains 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 under-voltage (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 IC, together with an independent, accurate reference generator.
- Over-Voltage, Under-Voltage, and Current Sensing Circuits all included.
- Reference Voltage Trimmed to 1% Accuracy.
- SCR "Crowbar" Drive of 300mA.
- Programmable Time Delays.
- Open-Collector Outputs and Remote Activation Capability.
- Total Standby Current less than 10mA. High Reliability Features
- Available to MIL-STD-883, ¶ 1.2.1
- MSC-AMS
