The industry's first gate drive optocoupler with integrated flyback controller brings a highly compact and energy-efficient 6-channel IGBT driver module
[October 17, 2013] Avago Technologies (Nasdaq: AVGO), a leading supplier of analog interface components for wired, wireless and industrial applications, today announced the launch of a new 2.5A smart door drive optocoupler ACPL-32JT for automobiles, It can bring about power isolation in automotive power systems. This product integrates a flyback controller to support regulated output, as well as complete anti-failure IGBT diagnosis, protection and fault return functions that can meet the requirements of automotive safety functions. ACPL-32JT is very suitable for electric vehicle (EV, Electric Vehicle), hybrid electric vehicle (HEV) and plug-in vehicles such as automobile power system traction inverter, power converter, battery charger, air conditioner and oil pump motor drive Plug-in Hybrid Electric Vehicle (PHEV) application.
ACPL-32JT expands Avago's automotive R2Coupler series products. The main goal is to further simplify the design of automotive multi-channel IGBT drive circuit board. By integrating the flyback controller, ACPL-32JT can use fewer discrete components and match the volume. Small high-efficiency transformer, thus reducing the overall footprint and minimizing electromagnetic interference (ElectromagneTIc Interference, EMI) and noise coupling between IGBT channels, ACPL-32JT can help automotive power module design engineers develop a highly compact and energy-efficient 6-channel IGBT module.
At present, more than 50 EV, HEV, PHEV manufacturers and suppliers have adopted or are importing Avago's automotive R2Coupler products. Applications include battery management systems, power traction inverters, converters, chargers, air-conditioning compressors, Heater, oil pump, CAN bus interface, simulated environment sensing and fault feedback system, etc.

· Integrated flyback controller supports high voltage side power isolation
IGBT fail-safe protection: desaturation detection, IGBT soft turn-off, fault feedback, undervoltage lockout (UVLO) with feedback and active Miller clamp
· 8V to 18V wide input voltage range
· 2.5A maximum peak output current
· Vcm = 1, minimum 50 kV / μs common mode rejection (CMR) capability at 500V
· Simplify SO-16 package and minimize printed circuit board space and cost
Wide operating temperature range from -40 ° C to + 125 ° C
· Safety certification: UL1577, CSA and IEC / EN / DIN EN 60747-5-5 (please note that these important safety standards are not related to non-optical isolators such as magnetic isolators and capacitive isolators)
Avago will exhibit ACPL-32JT at the 2013 VDI International Conference held in Germany from October 16th to 17th.
Cheng-Dee Lee, Business Development Director of Avago's Isolation Products Division, said: "With the requirements of government regulations and energy-saving trends, the market for EV, HEV and PHEV automotive products will continue to grow. Avago's new ACPL-32JT will bring The isolated power supply compact smart door drive customers provide an effective solution to meet the strict size and safety requirements of automotive power systems. "
