Automotive R²Coupler™ Smart Gate Drive Optocoupler

Currently Viewing:

ACPL-32JT is a 2.5A Automotive R2Coupler Smart Gate Drive Optocoupler, which features integrated flyback controller for isolated DC-DC converter, IGBT Desaturation sensing with fault feedback, Under-Voltage LockOut (UVLO) with soft-shutdown and fault feedback and active Miller current clamping.   The fast propagation delay and tight 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, and is suitable for traction power train inverter, power converter, battery charger, air-conditioner and oil pump motor drives in HEV and EV applications.

Avago R2Coupler isolation products provide the reinforced insulation and reliability needed for critical automotive and high temperature industrial applications.
