FEBFOD8332-GEVB: Input LED drive, 2.5 A output current, IGBT driven optocoupler with desaturation detection, isolation fault detection and active Miller clamping

Fairchild FEBFOD8332-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 FEBFOD8332-GEVB consists 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. FEBFOD8332-GEVB herein refers to FEBFOD8332-GEVB or FEBFOD8332-GEVB. The key difference between these two products is the reset mechanism. The

FAULT signal is reset when VLED1+ is pulled from LOW to HIGH for FEBFOD8332-GEVB or automatically after tDESAT(MUTE) for FEBFOD8332-GEVB.

The FEBFOD8332-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.
