Description
Avago’s ACPL-337J gate drive optocoupler features fast
propagation delay with excellent timing skew perfor-
mance. Smart features that are integrated to protect
the IGBT include IGBT desaturation detection with soft-
shutdown protection and fault feedback, undervoltage
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 driving
IGBTs and power MOSFETs used in motor control and
inverter applications.
Avago isolation products provide reinforced insulation
and reliability that delivers safe signal isolation critical in
high voltage and noisy industrial applications.

Product Overview Description
The ACPL-337J is a highly integrated power control device that incorporates all the necessary components for a
complete, isolated IGBT gate drive circuit. It features IGBT desaturation detection with soft-shutdown protection and
fault feedback, undervoltage lockout and feedback, and active Miller current clamping in a SO-16 package. Direct LED
input with or without integrated LED driver allows flexible logic configuration and differential current mode driving
with low input impedance, greatly increasing its noise immunity.
