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.
