Description
The ACPL-332J is an advanced 2.5 A output current, easy-
to-use, intelligent gate driver which makes IGBT V
CE
fault
protection compact, affordable, and easy-to implement.
Features such as integrated V
CE
detection, under
voltage lockout (UVLO), “soft” IGBT turn-off, isolated
open collector fault feedback and active Miller clamping
provide maximum design flexibility and circuit protec-
tion.
The ACPL-332J contains a GaAsP LED. The LED is optically
coupled to an integrated circuit with a power output
stage. ACPL-332J is ideally suited for driving power IGBTs
and MOSFETs used in motor control inverter applications.
The voltage and current supplied by these optocouplers
make them ideally suited for directly driving IGBTs with
ratings up to 1200 V and 150 A. For IGBTs with higher
ratings, the ACPL-332J can be used to drive a discrete
power stage which drives the IGBT gate. The ACPL-332J
has an insulation voltage of V
