PROFET™ Load Guard 12V with Adjustable Overcurrent Limitation for Automotive ADAS Applications

Infineon Technologies has introduced the new automotive smart high-side power switch portfolio PROFET that offers maximum load flexibility for multiple power distribution use cases and ADAS applications with adjustable overcurrent limitation and capacitive load switching mode. These new PROFET Load Guard 12V dual- and single-channel devices with a wide current limitation range between 0.3 and 8.7 A allows the protection level to be set according to the system requirements without microcontroller involvement.

The PROFET Load Guard 12V family’s wide operating voltage range from 3 V to 28 V, combined with the adjustable overcurrent limitation and the CLS mode, provides maximum load flexibility. The CLS mode allows to charge several millifarads while remaining within the safe operating area (SOA) of the smart high-side power switches, increasing the overall system robustness.

Rated at 2-3 A, the family consists of two 90 mΩ and two 50 mΩ devices, both available as single- and dual-channel automotive smart high-side power switches. The proven PG-TS-DSO-14 package provides high compatibility with other SMART7 devices such as the PROFET +2 12V. Loads with a high capacitive share can be easily addressed via the integrated CLS mode, allowing large capacitors to be rapidly charged within the safe operating area (SOA) of the PROFET Load Guard 12V.
