SG3543 - Power Supply Output Supervisory Circuit
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 eit
SG3543 Features
* 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.
