ACPL-344JT-500E

Avago’s Automotive 2.5Amp Gate Drive Optocoupler features fast propagation delay with excellent timing skew performance. Smart features that are integrated to protect the IGBT include IGBT desaturation sensing with softshutdown protection and fault feedback, under voltage lockout and feedback and active Miller current clamping. This full featured and easy-to-implement IGBT gate drive optocoupler comes in a compact, surface-mountable SO- 16 package for space-savings. It is suitable for traction power train inverter, power converter, battery charger, air-con and oil pump motor drives in HEV and EV applications and satisfies automotive AEC-Q100 semiconductor requirements.
