Infineon BTS50080-1TMA: High-Current Smart Switch for Automotive and Industrial Applications

The demand for robust, efficient, and intelligent power management solutions is rapidly growing across the automotive and industrial sectors. Addressing this need, Infineon Technologies introduces the BTS50080-1TMA, a high-performance PROFET™ (Protected MOSFET) +2 smart high-side power switch. This device is engineered to deliver outstanding reliability and diagnostic capabilities for controlling heavy resistive, capacitive, and inductive loads with currents up to 80 A.

At the core of the BTS50080-1TMA is a deeply embedded protection and monitoring features. It integrates a low-ohmic N-channel power MOSFET, enabling very low typical on-state resistance (R_DS(on)) of just 0.5 mΩ. This exceptional efficiency minimizes power losses and heat generation, which is critical for energy-sensitive and thermally constrained applications. The device is housed in a TOLL (TO-Leadless) package, which offers an excellent power-to-size ratio and superior thermal performance due to its exposed cooling pad, facilitating effective heat dissipation.

A key strength of this smart switch is its comprehensive suite of integrated protection functions. These include protection against over-load, short-circuit, over-temperature, and over-voltage conditions. Furthermore, it provides advanced diagnostic feedback such as current sense, open-load detection, and fault status reporting to the microcontroller. This level of intelligence allows for predictive maintenance and enhanced system safety, preventing catastrophic failures and reducing downtime.

The BTS50080-1TMA is particularly suited for a wide array of demanding applications. In the automotive domain, it is ideal for driving high-current loads like seat heaters, PTC heaters, and motor control systems. In industrial automation, it reliably manages solenoids, actuators, and power distribution units. Its AEC-Q100 qualification ensures it meets the stringent reliability standards required for automotive electronics.

ICGOOODFIND: The Infineon BTS50080-1TMA stands out as a premier solution for designers seeking to combine high power handling with intelligent control and robust protection. Its extremely low R_DS(on), advanced diagnostic features, and compact TOLL package make it an exceptional choice for next-generation automotive and industrial systems where efficiency, reliability, and space are paramount.
