SG1543 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;.
