Infineon BTS6143DXT: High-Current PROFET™ Smart Switch for Automotive and Industrial Applications

The Infineon BTS6143DXT represents a state-of-the-art high-current PROFET™ (Protected MOSFET) smart power switch, engineered to meet the rigorous demands of both automotive and industrial applications. Combining robust performance with advanced diagnostic and protection features, this device is designed to drive resistive, capacitive, and inductive loads with exceptional reliability and efficiency.

At its core, the BTS6143DXT integrates a vertical power MOSFET with a continuous current capability of up to 32 A, making it suitable for high-load applications such as automotive heating systems, power seat modules, industrial motor controls, and solenoid driving. Its low on-state resistance (RDS(on)) ensures minimal power dissipation, which enhances energy efficiency and reduces thermal stress, contributing to longer system life and improved performance.

A key strength of this PROFET™ switch is its comprehensive suite of integrated protection features. These include protection against overload, short-circuit, over-temperature, and over-voltage conditions, safeguarding both the device and the connected load from potential damage. Additionally, the device offers advanced diagnostic functions such as current sense feedback with adjustable gain, open-load detection in on and off states, and ground loss protection. These capabilities enable precise system monitoring and fault reporting, which are critical for maintaining operational safety and facilitating predictive maintenance.

The BTS6143DXT is housed in a DPAK (TO-252) surface-mount package, optimized for efficient thermal management and compact PCB design. Its automotive-grade qualification (AEC-Q100 compliant) ensures reliability under harsh environmental conditions, including wide temperature ranges and high-voltage transients typical in 12 V and 24 V automotive systems.

ICGOFIND: The Infineon BTS6143DXT PROFET™ smart switch stands out as a high-performance, highly integrated solution for demanding high-current switching tasks. Its combination of robust protection, accurate diagnostics, and high power density makes it an ideal choice for next-generation automotive and industrial systems where reliability, safety, and efficiency are paramount.
