●The FOD8318 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. It consists of an integrated gate drive optocoupler featuring low R CMOS transistors to drive the IGBT from rail to rail and an integrated high-speed isolated feedback for fault sensing. The FOD8318 has an active Miller clamp fuction to shut off the IGBT during a high dv/dt situation without the need of a negative supply voltage. It offers critical protection features necessary for preventing fault conditions that lead to destructive thermal runaway of IGBTs.It utilizes Fairchild’s proprietary coplanar Optoplanar® packaging technology , and optimized IC design to achieve high noise immunity, characterized by high common mode rejection and power supply rejection specifications. The device is housed in a compact 16-pin small outline plastic package that meets the 8 mm creepage and clearance requirements.
