FEBFOD8333-GEVB

Fairchild FEBFOD8333-GEVB smart gate driver optocoupler, an advanced 2.5 A output current IGBT drive optocoupler, offers the critical protection necessary for preventing fault conditions that lead to destructive thermal runaway of IGBTs. Pin-for-pin compatible with current solutions, the FEBFOD8333-GEVBconsists of an integrated gate drive optocoupler featuring low RDS(ON) CMOS transistors to drive the IGBT from rail-to-rail and high-speed isolated feedback circuitry for fault sensing. It is ideally suited for driving fast- switching power IGBTs and MOSFETs. FEBFOD8333-GEVB herein refers to FOD8332 or FOD8333. The key difference between these two products is the reset mechanism. TheFAULT signal is reset when VLED1+ is pulled from LOW to HIGH for FOD8332 or automatically after tDESAT(MUTE) for FOD8333.

The FEBFOD8333-GEVB offers best-in-class noise immunity, resulting from its proprietary Optoplanar coplanar packaging technology. The optoplanar technology ensures safe insulation thickness of more than 0.4 mm in attaining reliable high-voltage isolation, certified by UL1577 and DIN EN/IEC60747-5-5 standards.
