FOD8316
2.5 A Output Current, IGBT Drive Optocoupler with
Desaturation Detection and Isolated Fault Sensing

High Noise Immunity Characterized by
Description
The FOD8316 is an advanced 2.5 A output current
IGBT drive optocoupler capable of driving most 1200 V /
150 A 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. The FOD8316 offers critical protection features
necessary for preventing fault conditions that lead to
destructive thermal runaway of IGBTs.
The device utilizes Fairchild’s proprietary Optoplanar
®
coplanar packaging technology, and optimized IC design
to achieve high noise immunity, characterized by high
common-mode rejection and power supply rejection
specifications.
The FOD8316 consists of an integrated gate drive opto-
coupler featuring low R
DS(ON)
CMOS transistors to drive
the IGBT from rail-to-rail and an integrated high-speed
isolated feedback for fault sensing. The device is housed
in a compact 16-pin small-outline plastic package which
meets the 8 mm creepage and clearance requirements.
