Limitation of the Maximum Input Power (M.P.L.): Calculation of Input Power for Overload Protection Over Heating Detection (O.H.D.): to Prevent the Power Switch from Excessive Heating Latched Disabling Mode When one of the following faults is detected: EHT overvoltage, Winding Short Circuit (WSCD), excessive input power (M.P.L.), power switch over heating (O.H.D.), a counter is activated If the counter is activated for a time that is long enough, the circuit gets definitively disabled. The latch can only be reset by removing and then re-applying power GreenLine is a trademark of Motorola, Inc. This document contains information on a prod Pb-Free Package is Available
