airchild Semiconductor's FOD8316/FOD8318, smart gate drive optocouplers, are 2.5A output current, IGBT drive optocouplers, offer the critical protection necessary for preventing fault conditions that lead to destructive thermal runaways of IGBTs. This new product family is comprised of high-speed isolated feedback for fault sensing and is ideally suited for driving fast-switching power IGBTs and MOSFETs. The device consists of an integrated gate drive optocoupler featuring low RDS(ON) CMOS transistors to drive the IGBT from rail-to-rail. The FOD8316/FOD8318 offers best-in-class noise immunity resulting from its Optoplanar® coplanar packaging technology. The Optoplanar® technology ensures safe insulation thickness of more than 0.4 millimeters in attaining reliable high-voltage isolation, certified by UL1577 and DIN EN/IEC60747-5-5 standards. FOD8318 provides an Active Miller Clamp function to shut off the IGBT during high dv/dt situations without the need of a negative supply voltage. This enables simpler design and increased reliability.
