Overview
The BTS5045-2EKA is part of Infineon Technologies' PROFET™+ 12V family, which consists of high-side smart power switches designed for automotive applications. These devices integrate a DMOS power transistor and CMOS logic circuitry, offering advanced diagnostic and protection features. The PROFET™+ 12V family is known for its high short-circuit and energy robustness, as well as protection against overload, overvoltage, short-circuit, excessive temperature, loss of ground, power supply loss, and electrostatic discharge (ESD). These switches are available in single, dual, and four-channel configurations and are packaged in DSO-8 and DSO-14 exposed pad packages.
