Power PROFET™ High-Side Switches
More Products for Cost Effective Power Distribution Architectures are Available Now!
Infineon's Power PROFET™ protected high-side switches supports the trend towards decentralized, intelligent and cost effective vehicle power distribution architectures. Power PROFET™ is a benchmark family of ultra-low ohmic protected high-side switches (1.0mΩ to 2.5mΩ) with integrated protection functions and diagnostics for automotive and 12V industrial markets. The devices are especially designed to drive high current loads of 20 to 40A DC and to replace high current relays and fuses in a wide range of high energy applications (e.g. module main switches and trailer node supply) and heating (e.g. PTC heaters and rear defoggers).
Portfolio
Today, the Power PROFET family consists of four pin-compatible switches controlling currents from 20A to 40A DC. They share the same feature set. Only their on-state resistance RDS(ON) scales with 1.0mΩ, 1.5mΩ, 2.0mΩ, or 2.5mΩ for each device.
For the easy Evaluation of the Power PROFET™ Infineon offers two shields for Arduino:
