FOD8332: 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 IG...
  • 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 used in motor control inverter applications and high-performance power systems. The FOD8332 offers critical protection features necessary for preventing fault conditions that lead to destructive thermal runaway of IGBTs.
    The device utilizes Fairchild’s proprietary Optoplanar® coplanar packaging technology and optimized IC design to achieve reliable high isolation voltage and high noise immunity, characterized by high common-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 (AlGaAs) 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 aluminium gallium arsenide (AlGaAs) LED optically coupled to an integrated high-speed feedback circuit for fault sensing.
