Description
The FOD8332 is an advanced 2.5 A output current IGBT
drive optocoupler capable of driving medium power
IGBTs with ratings up to 1,200 V and 150 A. It is suited
for fast-switching driving of power IGBTs and
MOSFETs in motor control inverter applications and
high-performance power systems. The FOD8332 offers
protection features necessary for preventing fault condi-
tions that lead to destructive thermal runaway of IGBTs.
The device utilizes Fairchild’s proprietary Optoplanar
®
coplanar packaging technology and optimized IC design
to achieve reliable high isolation and high noise immunity,
characterized by high common-mode rejection and power
supply rejection specifications. The device is housed in a
wide-body 16-pin small-outline plastic package.
The gate-driver channel consists of an aluminum gallium
arsenide (AlGaAs) light-emitting diode (LED) optically
coupled to an integrated high-speed driver circuit with a
low-R
DS(ON)
MOSFET output stage. The fault-sense
channel consists of an aluminium gallium arsenide
(AlGaAs) LED optically coupled to an integrated high-
speed feedback circuit for fault sensing.
