Introduction

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 optocoupler featuring low RDS(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.
