描述 Description

The FOD8316 is an advanced 2.5A Output Current IGBT Drive Optocoupler, capable of driving most 1200V/150A IGBTs. It is ideally suited for fast switching driving of power IGBTs and MOSFETs used in motor control inverter applications and high performance power systems. It offers critical protection features necessary for preventing fault conditions that lead to destructive thermal runaway of IGBTs. It utilizes Fairchild’s patented coplanar packaging technology, Optoplanar?

, and optimized IC design to achieve high noise immunity, characterized by high common mode rejection and power supply rejection specifications.
