Infineon BTS7006-1EPP: High-Current PROFET™ Smart Switch for Robust Automotive Applications

The increasing complexity of automotive electrical systems demands highly reliable, intelligent, and robust power management solutions. Addressing this need, Infineon Technologies introduces the BTS7006-1EPP, a standout member of its PROFET™ (Protected MOSFET) family of smart high-side switches. This device is engineered to deliver exceptional performance and protection for a wide array of demanding automotive applications, from powertrain systems and safety modules to advanced body electronics.

At its core, the BTS7006-1EPP is designed to control high-current loads with precision and intelligence. It features a continuous current capability of up to 28 A per channel, making it ideal for driving resistive, capacitive, and inductive loads such as motors, heaters, and solenoids. Its integrated N-channel power MOSFET provides very low typical on-state resistance (R_DS(on)), which minimizes conduction losses, improves system efficiency, and reduces heat generation—a critical factor in the thermally challenging environment of an automotive engine compartment.

What truly defines the PROFET™ technology is its comprehensive suite of embedded protection and diagnostic features. The BTS7006-1EPP offers robust protection against overload, short-circuit, and overtemperature conditions, safeguarding both the switch itself and the connected load. Furthermore, it includes advanced diagnostics such as current sense, open-load detection, and protection against ground loss and reverse battery voltage. The current sense (IS) pin provides a proportional current mirror output, enabling real-time load monitoring without the need for external shunt resistors. This allows microcontrollers to make informed decisions, supporting predictive maintenance and functional safety goals.

The device’s robustness is further enhanced by its high immunity to electrostatic discharge (ESD) and its ability to withstand harsh electrical transients common in the automotive environment, such as load dump and inductive kickback. Housed in a thermally enhanced, surface-mountable PG-TO263-7 package, the BTS7006-1EPP ensures excellent power dissipation and long-term reliability. Its design is fully AEC-Q100 qualified, guaranteeing compliance with the stringent quality and reliability standards required for automotive components.

ICGOODFIND: The Infineon BTS7006-1EPP PROFET™ smart switch is a superior solution for modern vehicle design, offering high-current switching, integrated protection, and detailed diagnostics in a robust package. It empowers engineers to build more efficient, reliable, and intelligent automotive systems, simplifying design while enhancing overall system safety.
