onsemi FOD8318 IGBT Drive Optocouplers

onsemi's FOD8318 IGBT Drive Optocouplers are an advanced 2.5A output current IGBT drive optocoupler capable of driving most 1200V / 150A IGBTs. They are 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 RDS(on) 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 function 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.
