Infineon BTT60501ERAXUMA1 High-Current PROFET™ Power Switch for Automotive Applications

The rapid evolution of automotive electronics demands robust, intelligent, and highly efficient power management solutions. Addressing this need, Infineon Technologies introduces the BTT60501ERAXUMA1, a state-of-the-art high-current PROFET™ (Protected FET) power switch designed specifically for the rigorous demands of modern vehicles. This device stands out as a critical component for driving resistive or inductive loads in a wide array of automotive applications, from body control modules and powertrain systems to advanced driver-assistance systems (ADAS).

Engineered with Infineon’s proven SMART7 technology, the BTT60501ERAXUMA1 integrates a vertical N-channel power MOSFET with a CMOS control chip into a single, compact package. Its key strength lies in its ability to handle high output currents up to 21A, making it ideal for controlling demanding loads such as motors, heaters, and LEDs. A paramount requirement in automotive design is reliability and protection. This PROFET™ device excels with its comprehensive suite of embedded protection features, including over-load protection, short-circuit protection, over-temperature shutdown, and over-voltage clamp. These features not only safeguard the switch itself but also protect the microcontroller and the load, thereby significantly enhancing the overall system's robustness and longevity.

Furthermore, the device offers advanced diagnostic capabilities such as current sense feedback, open-load detection, and protection status flag reporting. This level of intelligence allows for precise system monitoring and fault detection, which is indispensable for functional safety and compliance with standards like ISO 26262. Housed in a space-saving, surface-mountable PG-TSDSO-14 package, it also provides excellent power dissipation and is designed to operate seamlessly in the harsh automotive environment, with a wide operating voltage range and high electrostatic discharge (ESD) protection.

ICGOOODFIND: The Infineon BTT60501ERAXUMA1 PROFET™ represents a superior integration of power, protection, and intelligence, providing automotive system designers with a reliable and efficient solution to meet the increasing complexity and safety requirements of next-generation vehicles.
