Auto-Grade Photovoltaic MOSFET Driver Debuts at Electronica

MUNICH — Avago used Electronica 2014 to launch the ACPL-K30T, a photovoltaic MOSFET driver qualified to AEC-Q100 Grade 1 test guidelines. It is the first such device to be usable in "under-the-hood" high-temperature automotive applications.

The ability to meet the high-temperature and reliability requirements of automotive applications came about through refinement of the company's optical/LED technology, Mark Gray, field applications manager for Avago Technologies GmbH, told us. The MOSFET is a key part of the company's overall strategy to press further into automotive applications.

Using its R2 Coupler-based products, Avago has design wins in more than 50 car models in applications ranging from analog sensing, oil pumps, chargers, and converters to drive systems, air conditioner compressors, heaters, battery management systems (for electric vehicles), and CAN bus interfacing.

The ACPL-K30T has an operating temperature range of -40 to 125°C, can drive high-voltage MOSFETs with up to 1,000V isolation at 2.2 Amps, and can be used both for under-the-hood and battery management systems in modern electric vehicles, hybrid electric vehicles, and plug-in hybrid electric vehicles.

Other features include an open-circuit voltage and a short-circuit current of 7 V and 5 mA, respectively (typical, at an LED drive current of 10 mA), and a turn-on time of 40 ms (typical).

The ACPL-K30T is priced starting at $1.87 in 1,000-piece quantities. Samples and production quantities are available now.
