IP3543 Overview
The IP1543 and IP3543 power supply supervisory circuits contain all the functions necessary to monitor and control the output of a sophisticated power supply system. Included on the chip are over-voltage (O.V.) sensing with externally programmable delay used to trigger an external SCR “Crowbar”, under-voltage (U.V.) sensing with externally programmable delay used to sense either the power supply output or the line...
