电源监控电路 Power Supply Supervisory Circuit
DESCRIPON
The monolithic integrated circuits contain 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 undervoltage 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 device, together with an independent, accurate reference generator.
