SG2543 Datasheet Power Supply Output Supervisory Circuit

Manufacturer: Microsemi (now Microchip Technology)

Overview: SG1543/SG2543/SG3543 Power Supply Output Supervisory Circuit.

General Description

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;
