Infineon BTT6050-2ERA: A High-Current PROFET™ Smart Switch for Automotive Applications

Modern automotive systems demand robust, intelligent, and highly reliable solutions to manage the ever-increasing number of electronic functions. At the heart of many of these systems—controlling actuators, pumps, heaters, or lighting—are high-side switches. The Infineon BTT6050-2ERA stands out as a premier example of this technology, representing a significant leap in performance and integration for automotive power management.

This device is a member of Infineon's esteemed PROFET™ (Protected FET) family of smart high-side switches. It is a dual-channel switch capable of handling high output currents up to 5.5 A per channel, making it exceptionally suited for driving demanding inductive, capacitive, and resistive loads. Engineered to meet the stringent requirements of the automotive environment, it operates seamlessly within a wide supply voltage range from 5.5 V to 40 V, tolerating load-dump conditions without breaking a sweat.

The "smart" in this smart switch is delivered through a suite of advanced diagnostic and protection features. The BTT6050-2ERA provides precise feedback to the microcontroller on channel status, load current, and overtemperature conditions. Its integrated protections are comprehensive, guarding against overload, short-circuit to ground or battery, overtemperature, and electrostatic discharge (ESD). Crucially, it also features an open-drain diagnosis pin that alerts the system to any fault condition, enabling predictive maintenance and enhancing overall system safety and reliability.

A key advantage of this solution is its high level of integration. By combining two powerful switches, control logic, and protection circuits into a single compact PG-TO263-7 package, the BTT6050-2ERA simplifies PCB design, reduces the component count, and saves valuable board space. This integration directly contributes to increased system reliability and lower overall assembly costs.

Furthermore, the device boasts an extremely low standby current, a critical parameter for automotive applications where minimizing battery drain, especially in ignition-off scenarios, is paramount. Its efficient design ensures that it contributes to the vehicle's energy efficiency goals.

In application, the BTT6050-2ERA is ideal for a wide array of uses within the body control module, junction box, or dedicated control units. It is perfectly positioned to drive DC motors, LEDs, solenoids, and heating elements found in power seats, window lifters, sunroofs, adaptive lighting systems, and various comfort and convenience features.

ICGOODFIND: The Infineon BTT6050-2ERA is a powerhouse of integration and intelligence. It successfully merges high-current handling, ruggedness for the automotive environment, and sophisticated diagnostic capabilities into a single package. For engineers designing next-generation automotive body electronics, this PROFET™ switch offers a reliable, efficient, and space-saving solution that simplifies design while boosting performance and safety.
