Infineon BTS50010-1TAD: High-Current Smart Switch for Automotive and Industrial Applications

The demand for robust, intelligent power management solutions continues to grow across the automotive and industrial sectors. Addressing this need, Infineon Technologies has developed the BTS50010-1TAD, a high-current PROFET™ (Protected MOSFET) smart switch that sets a new benchmark for performance, integration, and reliability in switching applications.

This single-channel, high-side switch is engineered to control loads such as motors, heaters, and lamps with currents of up to 35 A continuous. Its exceptional current-handling capability makes it an ideal solution for demanding applications like electric power steering (EPS) systems, engine management modules, industrial automation controllers, and heavy-duty solenoid control.

A key strength of the BTS50010-1TAD lies in its advanced diagnostic and protection features, which are critical for ensuring system safety and longevity. It provides comprehensive real-time diagnostic feedback to the microcontroller, including precise load current sense information, warnings for overtemperature and short-circuit conditions, and detection of open-load and overvoltage events. This intelligence allows for predictive maintenance and swift system reactions to faults. The device is also exceptionally robust, featuring protection against reverse battery conditions, load-dump pulses, and ESD events, ensuring operational stability in the harsh electrical environments typical of automotive applications.

Furthermore, the device offers a very low standby current, which is a vital parameter for modern vehicles and equipment where energy efficiency and meeting quiescent current targets are paramount. Housed in a TO-263-7 package with an exposed cooling pad, the switch achieves excellent thermal performance, enabling efficient heat dissipation and a compact PCB design.

In summary, the Infineon BTS50010-1TAD provides a powerful, intelligent, and highly reliable all-in-one solution that simplifies design, enhances system durability, and drives innovation in next-generation automotive and industrial systems.

ICGOOODFIND: The Infineon BTS50010-1TAD stands out as a superior smart high-side switch, integrating high-current handling, advanced diagnostics, and robust protection into a single package.
