Description
Avago's ACPL-302J 2.5 Amp Gate Drive Optocoupler
features integrated flyback controller for isolated DC-DC
converter, IGBT desaturation sensing with fault feedback
and soft-shutdown, Under-Voltage LockOut (UVLO) with
feedback and active Miller current clamping. The fast
propagation delay with excellent timing skew perfor-
mance 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 driving IGBTs and power MOSFETs used in motor
control and inverter applications.
