MP6211/mp6212 will be shutdown only if the overcurrent condit i o n stays lo ng enough to trigger thermal protection. trigger overcurrent protection for different overload conditions o c curring in app lication s : 1) the output has been shorted or overloaded before the d evice is ena bled or inpu t applied. mp mp621 1/mp6212 detects the short or overload and immediately switches into a constant-cur rent mode. 2) a short or a n overload occurs after t he device is enab led. after the cu rrent-limit circuit ha s been tripped (reached the trip current threshold), t he device switches into constant- current mode. however, high cu rrent ma y flow for a short perio d of time before the current-limit circuit can r eact. 3) output current has bee n gradually increased beyond the recommend ed operatin g current. the load current rises until the trip current threshold is reached or until the thermal limit of the device is exce eded. the MP6211/ mp6212 is capable of de livering curr ent up to the trip cur r ent thresh old without damaging the device. once the trip threshold has been reached, t he device switches into its constant-cur rent 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. thermal protection the purpose of thermal protect i on is to prevent damage in the ic by all o wing exceptive current to flow and he ating the ju nction. the die temp. is internally monitored un til the ther mal limit i s reached. once this te mp. is reached, the sw itch will turn off and allow th e chip to co ol. the swit ch has a built- i n hysteresis. under-volta ge lockout (uvlo) this circu i t is used to monitor the input voltage t o ensure tha t the MP6211/6212 is operat ing correctly. this uvlo circuit a l so ensures t hat there is no operation until the input voltage reaches the minimu m spec. enable the logic p i n disab l es the ch ip t o reduce t he supply current. the device will oper ate once th e enable sign al reaches t he appropriate level. the input is compatible with both coms and ttl.
