Infineon BTS6163D: High-Side Smart Power Switch for Robust Automotive and Industrial Applications

Modern automotive and industrial systems demand power switches that are not only efficient but also exceptionally robust, intelligent, and reliable. Addressing these critical needs, the Infineon BTS6163D stands out as a premier high-side smart power switch engineered to deliver superior performance in the most demanding environments.

As a PROFET™ (Protected MOSFET) device, the BTS6163D integrates a vertical power MOSFET with a comprehensive suite of protection and diagnostic features onto a single chip. This high level of integration simplifies circuit design, reduces board space, and enhances overall system reliability. It is specifically designed to drive resistive or inductive loads, such as solenoids, valves, motors, and lamps, with a continuous current capability of up to 28A.

The core strength of the BTS6163D lies in its advanced protective functionalities, which ensure operational integrity under fault conditions. Key features include robust overcurrent protection with active current limiting, which clamps the output current during a short circuit to prevent catastrophic failure. It also incorporates overtemperature shutdown with automatic restart, safeguarding the device and the load from thermal damage. Furthermore, its overvoltage protection (including load-dump resilience) and electrostatic discharge (ESD) protection make it ideal for the electrically harsh 12V and 24V automotive power nets.

Beyond protection, the device offers sophisticated diagnostic feedback. The status output pin provides valuable information to the microcontroller, flagging conditions like open-load (both in on and off-state), short-to-ground, and overtemperature pre-warning. This capability for predictive maintenance is invaluable for automotive body controllers and industrial automation systems, allowing for preemptive actions before a total failure occurs.

The device is housed in a TO-263-7 (D2PAK) package, offering an excellent thermal performance that is crucial for handling high power dissipation. Its very low typical on-state resistance (RDS(on) of just 7.5 mΩ) ensures minimal conduction losses, leading to higher efficiency and reduced heat generation.

ICGOOODFIND: The Infineon BTS6163D is a highly integrated and intelligent high-side switch that sets a benchmark for reliability. Its combination of high current handling, robust integrated protection, and precise diagnostic capabilities makes it an optimal solution for enhancing the performance and durability of modern automotive and industrial power systems.
