Infineon BTS50015-1TAD: High-Current PROFET™ Smart Switch for Automotive Applications

Modern automotive systems demand robust, intelligent, and highly reliable electronic components to manage the ever-increasing number of electrical loads. The Infineon BTS50015-1TAD stands out as a premier solution in this domain. This device is a High-Current PROFET™ (Protected FET) Smart Switch, engineered specifically for the rigorous demands of the automotive environment, offering superior performance and diagnostic capabilities for a wide range of applications.

At its core, the BTS50015-1TAD is a single-channel, high-side switch integrated into a TO-263-7 package, which provides an excellent power dissipation capability. Its most striking feature is its impressive continuous current rating of up to 30A. This high current-carrying capacity makes it an ideal choice for driving demanding loads such as heating elements, motors, and LED lighting systems within vehicles.

The "smart" in its designation is well-earned. The device incorporates a comprehensive suite of advanced protection and diagnostic functions that are crucial for automotive safety and reliability. These include protection against overload, short-circuit, over-temperature, and over-voltage conditions. Furthermore, it features current sense diagnosis with a programmable accuracy, allowing the system microcontroller to monitor the load status in real-time. This enables predictive maintenance and swift fault identification, which is vital for preventing system failures.

Another significant advantage is its very low standby current, which is a critical parameter for modern vehicles to minimize battery drain, especially when the car is turned off but certain systems remain in a standby mode. The switch is designed to be controlled directly by a microcontroller, thanks to its 3.3V and 5V logic compatible input, simplifying interface design.

The BTS50015-1TAD is AEC-Q100 qualified, guaranteeing its performance and reliability under the extreme temperature fluctuations and harsh conditions typical of automotive applications. It is a key enabler for systems in body control modules, powertrain, and battery management, contributing to the advancement of more sophisticated and safer vehicles.
