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 RDS(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.
