Infineon PROFET™ + 48V
Infineon’s PROFET™ + 48V family delivers smart high-side switches for 48 V systems with protection, diagnostics, multiple channel options and high short-circuit robustness.
The PROFET™ + 48V is specifically designed for 48 V systems, such as electric and mild-hybrid vehicles, central and decentral ECUs, ADAS loads, fuse and relay replacement, as well as certain industrial applications. The family offers an RDS (on) range from 35 to 200 mOhm. The modular family concept consists of single, dual, and four-channel devices. Beause of the modularity, different devices can be used on the same PCB footprint, which saves costs in case the load requirements change. Finally, some products are also pin- and function-compatible with Infineon's respective 24 V high-side power switch family (PROFET™ + 24V).
