Product Summary
During power-up, the UnderVoltage Lockout (UVLO) featureprevents the application ofinsufficient gate voltage to theIGBT, by forcing theHCPL-316J’s output low. Oncethe output is in the high state, theDESAT (VCE) detection feature ofthe HCPL-316J provides IGBTprotection. Thus, UVLO andDESAT work in conjunction toprovide constant IGBTprotection
