Fairchild Semiconductor's New Smart Gate Driver Optocoupler Provides Designers Isolated Gate Driving and Fault Sensing

The FOD8316 optocoupler offers the critical protection necessary for preventing fault conditions that lead to destructive thermal runaways of IGBTs. This new product family is comprised of high-speed isolated feedback for fault sensing and is ideally suited for driving fast-switching power IGBTs and MOSFETs. The device consists of an integrated gate drive optocoupler featuring low RDS(ON) CMOS transistors to drive the IGBT from rail-to-rail.

Features and Benefits:
2.5A output current driving capability for most 1,200V/150A IGBT
High noise immunity characterized by CMR: 35kV/µsec @Vcm-1500Vpk
1, 414V peak working insulation voltage and 8,000V peak transient isolation voltage rating
Output voltage swing rail-to-rail for low-power dissipation
Soft IGBT turn-off
High-speed: 500nsec propagation delay time
3.3V/5V, CMOS/TTL for logic input

Fairchild enables customers to drive innovation in their designs by developing solutions like the FOD8316 – which is part of Fairchild's comprehensive portfolio of high-performance optocouplers, power management ICs, high-voltage gate driver ICs, and discrete power IGBTs/MOSFETs. The FOD8316 offers best-in-class noise immunity resulting from its proprietary Optoplanar® coplanar packaging technology. The Optoplanar technology ensures safe insulation thickness of more than 0.4 millimeters in attaining reliable high-voltage isolation, certified by UL1577 and DIN EN/IEC60747-5-5 standards.
