Industry’s First Gate Drive Optocoupler With Integrated Flyback Controller Enables Highly Compact Energy-Efficient 6-Channel IGBT Driver Module

SAN JOSE, Calif. and SINGAPORE, Oct. 16, 2013 (GLOBE NEWSWIRE) — Avago Technologies (Nasdaq:AVGO), a leading supplier of analog interface components for wireless, wireline, and industrial applications, today unveiled the ACPL-32JT, a new automotive 2.5A smart gate drive optocoupler device that enables isolated power supply in automotive powertrain systems. The device features an integrated flyback controller supporting regulated output voltage and a full set of fail-safe IGBT diagnostics, protection and fault reporting in support of automotive functional safety requirements. The ACPL-32JT is ideal for use in automotive powertrain traction inverter, power converter, battery charger, air conditioner and oil pump motor drive for electric vehicle (EV), hybrid electric vehicle (HEV) and plug-in hybrid electric vehicle (PHEV) applications.

The ACPL-32JT expands Avago’s automotive R(2) Coupler(TM) family of products and is intended to further simplify automotive multi-channel IGBT driver board design. By integrating the flyback controller, the ACPL-32JT allows fewer discrete components and small high-efficiency transformer to be placed next to the IC thereby reducing the overall footprint and minimizing electromagnetic interference (EMI) and noise coupling between the IGBT channels. The ACPL-32JT enables automotive power module designers to develop highly compact energy-efficient 6-channel IGBT driver modules.

More than 50 automotive manufacturers and suppliers for EV, HEV and PHEV have adopted or are designing in Avago’s automotive R(2) Coupler products in battery management system, powertrain traction inverter, converter, charger, air conditioner compressor, heater, oil pump, CAN bus interface, analog sensing and fault feedback system.
