Power PROFET™ – Ultra-low ohmic smart high-side power switches

Power PROFET™ – Ultra-low ohmic smart high-side power switches

Power PROFET™ is a benchmark family of ultra-low ohmic protected high-side switches
(1.0 mΩ to 2.5 mΩ) with integrated protection functions and diagnostics for automotive
and 12 V industrial markets. The devices are especially designed to drive high current
loads of 20 to 40 A DC and to replace high current relays and fuses in a wide range of applications such as power distribution (e.g. module main switches and trailer node supply)
and heating (e.g. PTC heaters and rear defoggers).

Power PROFET™ switches are based on a new benchmark technology offering very high energy capability and are therefore an ideal driving solution for an increasing number of applications with high switching cycle requirements, e.g. starter relays in “start-stop” systems and electric brake vacuum pumps.

The BTS50015-1TAD is the lead product of this ultra-low ohmic protected high-side switch family available now.
