If you are working with MOSFET as high capacity switches in DC or (most particular) in AC, then chances are that you are already familiar with the Photovoltaic MOSFET Drivers such as the Vishay VOM1271. These chips provide 100% galvanic insulation between the MOSFETs and the controller circuit, and they also provide all the necessary voltage required to drive the MOSFET gates. Therefore, there is no need to design and add an extra insulated power supply to drive the FETs.
Avago presented their new ACPL-K30T in Electronica 2014. The ACPL-K30T is a photovoltaic MOSFET driver qualified to AEC-Q100 Grade 1 test guidelines. It is the first device of its kind able to operate in high temperatures and therefore making it suitable for "under-the-hood" 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|
Here is the datasheet for the ACPL-K30T
