Fairchild FOD8332V

光学耦合14243Vrms

Overview

The FOD8332V 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 FOD8332V 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.
