Infineon BTT6030-2EKA: High-Current PROFET™ Smart Switch for Robust Automotive Applications

The increasing complexity of automotive electronic systems demands highly reliable, efficient, and intelligent power management solutions. Addressing this need, Infineon Technologies introduces the BTT6030-2EKA, a standout member of its PROFET™ (Protected MOSFET) family of smart high-side switches. This device is engineered specifically to drive high-current loads in the harsh environment of modern vehicles, providing a robust and integrated solution for a wide array of applications.

Designed for Demanding Automotive Environments

As vehicles incorporate more electronic control units (ECUs), body control modules (BCMs), and advanced driver-assistance systems (ADAS), the requirement for robust switching components has never been greater. The BTT6030-2EKA is built to thrive in this setting. It features a dual-channel design, with each channel capable of handling a continuous current of up to 30 A. This high-current capability makes it ideal for controlling power-hungry loads such as heating elements, motors, and LEDs.

A key strength of this PROFET™ switch is its exceptional diagnostic and protection features. It incorporates a comprehensive suite of safeguards including overload protection, short-circuit protection, and overtemperature protection. Crucially, it also provides advanced diagnostic feedback to the microcontroller, such as current sense with a programmable sense ratio, load open-circuit detection, and detection of loss of ground. This level of intelligence allows for predictive maintenance and swift fault identification, which is critical for functional safety and meeting standards like ISO 26262.

Enhanced Reliability and System Integration

The device is housed in a space-saving, surface-mount PG-TO263-7-43 package, offering excellent thermal performance and power dissipation. Its very low on-state resistance (RDS(on)) minimizes conduction losses, leading to higher efficiency and reduced heat generation. This combination of a robust package and high efficiency ensures long-term reliability.

Furthermore, the BTT6030-2EKA is designed for reverse battery protection (-40 V) and is highly resistant to electrostatic discharge (ESD) and transients, such as those described in the ISO 7637 pulse standard. This inherent ruggedness protects both the switch itself and the sensitive downstream electronics, simplifying overall system design and enhancing durability.

Application Versatility

The versatility of the BTT6030-2EKA allows it to be deployed across the vehicle, including in:

Body & Convenience Systems: Powering seat heaters, window lifters, and sunroof motors.

Powertrain Systems: Controlling actuators, pumps, and solenoids.

ADAS and Lighting: Driving high-current LED arrays for headlights and other illumination functions.
