Description
The FOD8316 is an advanced 2.5A Output Current
IGBT Drive Optocoupler, capable of driving most 1200V/
150A IGBTs. It is ideally suited for fast switching driving
of power IGBTs and MOSFETs used in motor control
inverter applications and high performance power
systems. It offers critical protection features necessary
for preventing fault conditions that lead to destructive
thermal runaway of IGBTs.
It utilizes Fairchild’s patented coplanar packaging
technology, Optoplanar^®, and optimized IC design to
achieve high noise immunity, characterized by high
common mode rejection and power supply rejection
specifications.
It consists of an integrated gate drive optocoupler featur-
ing low R_DS(ON) CMOS transistors to drive the IGBT from
rail to rail and an integrated high speed isolated feed-
back for fault sensing. The device is housed in a com-
pact 16-pin small outline plastic package which meets
the 8mm creepage and clearance requirements.
