Rutronik UK adds Infineon Power Profet high-side switches
Designed to support decentralised vehicle power distribution, Infineon’s Power Profet protected high-side switches are now available from Rutronik UK.
They support the trend towards decentralised, intelligent and cost effective vehicle power distribution architectures, says the distributor. Power Profet is a family of low Ohmic protected high-side switches (1.0 to 2.5-milliOhmn) with integrated protection functions and diagnostics for automotive and 12V industrial markets.
The Power Profet devices are designed to drive high current loads of 20 to 40A DC and to replace high current relays and fuses in a range of high energy applications (e.g. module main switches and trailer node supply) and heating (e.g. PTC heaters and rear defoggers).
The Power Profet family consists of four pin-compatible switches controlling currents from 20A to 40A DC. They share the same feature set, with only theon-state resistance RDSon scales with 1.0, 1.5, 2.0, or 2.5milliOhm for each device.
There are two shields for Arduino available to evaluate the Power Profet. The low Ohmic smart high-side power switch family has high current
capability with up to 25, 29, 33 and 40A DC (INOM) and up to 150A inrush current.
Key features include protection performance of more than 1,000,000 short circuit cycles (Grade A according to AEC-Q100), integrated protection functions and diagnostics, operating voltage range from 8.0 to 18V; 3.3V to VS compatible logic input, very low leakage current at OUT pin and ESD protection.
Benefits cited by Rutronik UK include reducing the number of components at system level (relay driver, socket, fuses, connectors, free-wheeling diode), significantly decreasing the module size and cost. Power Profet devices can replace electromechanical relays, fuses and discrete circuits in power distribution and junction boxes, adds Rutronik UK.
