DATA SHEET .onsemi. Input LED Drive, 2.5 A Output Current, IGBT Drive Optocoupler with Desaturation Detection, Isolated Fault Sensing, and Active Miller Clamp Description The FOD8332 is an advanced 2.5 A output current IGBT drive optocoupler capable of driving medium- power IGBTs with ratings up to 1,200 V and 150 A. It is suited for fast- switching driving of power IGBTs and MOSFETs in motor- control inverter applications and high- performance power systems. The FOD8332 offers protection Features necessary for preventing fault conditions that lead to destructive thermal runaway of IGBTs. The device utilizes onsemi’s proprietary OPTOPLANAR® coplanar packaging technology and optimized IC design to achieve reliable high isolation and high noise immunity, characterized by high mon- mode rejection and power supply rejection specifications. The device is housed in a wide- body, 16- pin, small- outline, plastic package. The gate- driver channel consists of an aluminum gallium arsenide (Al Ga As) light- emitting diode (LED) optically coupled to an integrated high- speed driver circuit with a low- RDS(ON) MOSFET output stage. The fault- sense channel consists of an Al Ga As LED optically coupled to an integrated high- speed feedback circuit for fault sensing.
