Smart power switches

Driving stronger reliability with protection and diagnostics

Protect and diagnose your automotive and industrial applications against conditions like short-to-ground and open load. With adjustable current limit, high accuracy current sense, and a wide range of Rdsons, our family of smart high-side switches ample solutions for your specific use-case, ensuring your design is scalable and robust.


From headlights to tail lights, and everything in between, our family portfolio provides advanced protection and diagnostics for automotive applications like ADAS, Body/Lighting, Infotainment, and PowerTrain™ modules.


The TPS27S100 with high-accuracy current monitoring and adjustable current limit is ideal for applications like programmable logic controllers, motor valves, servo drives and control units.

High accuracy current sensing

Integrated current sense accuracy enables real-time monitoring for open-load and short-to-battery detection without any calibration needed, ultimately reducing product cost and test time.

Adjustable current limit for targeted protection

Our high side switches protect against inrush, overload, and short-circuit conditions. Adjustable current limit reduces PCB traces and connector sizes to lower system costs.

Robust, qualified solutions

Our devices are tested against the rigorous requirements of industry standards, including AEC-Q100, ISO-7637, and IEC-61000. Learn more about short-circuit testing and results for the AEC Q100-012 specification.
