ACPL-33JT
Automotive 2.5 Amp Gate Drive Optocoupler with
Integrated Flyback Controller for Isolated DC-DC
Converter, Integrated IGBT Desat Over Current
Sensing, Miller Current Clamping and UVLO Feedback
Data Sheet
Description
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.
Avago R2Coupler® isolation products provide reinforced
insulation and reliability that delivers safe signal isolation
critical in automotive and high temperature industrial
applications.
