MP6215 det ects the sho r t or overload and immediately switches in t o a constant -current mode. 2) a short or an overload occurs after t he device is enabled. after the current-limit cir c uit has been tripped (reached th e trip curren t threshold), t he device switches into constant- current mode. however, high current may flow for a sh ort period of time before the current-limit circuit can r eact. 3 output current has b een gradually increased beyond the recommende d operating current. the load cur r ent rises un til the trip cu rrent threshold is reached or until the ther mal limit of the device is exceed ed. the MP6215 is capable of d elivering cur r ent up to th e trip current thre shold withou t damaging the device. once the trip thr eshold has been reached, the device switches into its constant- current mode. flag response the flag pin is an open drain configuration. this fault will report a fail mode after an 8ms deglitch t i meout. this is used to e nsure that no false fau l t signals are reported. this intern al deglitch cir c uit elimina t es the ne ed for extend components. the flag pin is n ot deglitche d during an over temp. or a voltage lockout.
