Description
The FOD8316 is an advanced 2.5 A output current IGBT drive
optocoupler capable of driving most 1200 V /150 A 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. The FOD8316 offers critical 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 high noise
immunity, characterized by high common−mode rejection and power
supply rejection specifications.
The FOD8316 consists of an integrated gate drive optocoupler
featuring low RDS(ON) CMOS transistors to drive the IGBT from
rail−to−rail and an integrated high−speed isolated feedback for fault
sensing. The device is housed in a compact 16−pin small−outline plastic
package which meets the 8 mm creepage and clearance requirements.
