ACPL-33JT-500E

The ACPL-33JT Automotive 2.5 Amp Gate Drive Optocoupler features integrated flyback controller for isolated DC-DC converter, IGBT desaturation sensing and fault feedback, Under-Voltage LockOut (UVLO) with soft-shutdown and fault feedback and active Miller current clamping. The fast propagation delay with excellent timing skew performance enables excellent timing control and efficiency. This full feature optocoupler comes in a compact, surface-mountable SO-16 package for space-savings, is suitable for traction power train inverter, power converter, battery charger, air-conditioner and oil pump motor drives in HEV and EV applications.
