Avago optocoupler has flyback controller to drive IGBTs
The device’s 2.5A rail-to-rail output makes it suitable for driving IGBTs and power MOSFETs in industrial power inverters and motor drives.
“By integrating the flyback controller, the ACPL-302J allows fewer discrete components and small high-efficiency transformer to be placed next to the device thereby reducing the overall footprint and minimising electromagnetic interference (EMI) and noise coupling between IGBT channels,” said Avago.
The device also features integrated active Miller clamp, IGBT DESAT detection, and Under Voltage Lock-Out (ULVO) with feedback reducing bill of materials (BOM) cost and simplifying gate drive design.
High reinforced insulation voltage is 1,230V(peak) for high voltage applications. Creepage and clearance is 8.3mm.
Operating temperature is from -40 °C to +105 °C.
Safety approvals include CSA, UL and IEC/EN/DIN EN 60747-5-5.
