Company speeds move to 42 V automotive power systems

28 February 2001 News

Philips Semiconductors is leading the automotive industry's move from 13,8 to 42 V power systems by releasing a family of 75 V PowerMOS devices. Early release means customers can qualify the PowerMOS devices in time for incorporation into future product designs.

The 75 V PowerMOS family, which will be seen in vehicles from 2003, will help engineers to address the power needs of a wide range of 42 V automotive loads. The long awaited move to 42 V will give manufacturers the opportunity to increase the quantity of electronic equipment in vehicles. The result is that vehicle users will enjoy a far greater range of benefits from features, such as brighter headlamps and better brakes, new and powerful information and entertainment systems and more efficient airconditioning systems.

Pascal Langlois, Vice President and General Manager of the automotive market segment at Philips Semiconductors said, "Philips Semiconductors' early investment in 42 V power products is giving its customers the earliest possible opportunity to reap the technological and commercial benefits of moving to the new 42 V standard".

This move to 42 V is not only due to an increase in extra comfort and safety features but also because of mechanical systems being replaced gradually by electrical motors and actuators as part of a drive to increase efficiency and cut pollution.

Based on Philips Semiconductors' leading second generation TrenchMOS, the devices operate efficiently due to the low on-state resistance and fast switching for which the technology is renowned. The first products include 9 and 23 mW devices, in both TO220 and SOT404 packages, and 26 mW devices in D-PAK. All devices are available in both standard and logic level variants. Further devices are planned including 12 and 20 mW versions. In common with all Philips automotive MOSFETs the devices have been designed to meet the stringent requirements of automotive quality standard Q101.
