Infineon BTS6143D High-Current PROFET™ Smart High-Side Power Switch

The Infineon BTS6143D is a state-of-the-art High-Current PROFET™ (Protected FET) smart high-side power switch engineered for robust performance in demanding automotive and industrial applications. As part of Infineon’s PROFET™ family, this device integrates advanced protection, diagnostic features, and control functionalities into a single package, offering designers a compact and highly reliable solution for switching high-current loads.

A key feature of the BTS6143D is its high current handling capability, supporting loads up to several tens of amperes with a very low typical on-state resistance (RDS(on)). This results in reduced conduction losses and improved thermal performance, making it ideal for applications such as automotive power systems, motor drives, solenoid control, and heater management. The device operates over a wide voltage range and is designed to withstand harsh electrical environments, including load dump and reverse battery conditions.

The BTS6143D incorporates multiple embedded protection functions to enhance system safety and durability. These include overload protection, short-circuit protection, over-temperature shutdown, and over-voltage clamp. Additionally, the device provides diagnostic feedback via a dedicated status pin, which signals fault conditions such as overtemperature or open-load events in off-state. This enables real-time monitoring and swift system response, critical for maintaining operational integrity in safety-relevant applications.

Another significant advantage is its efficient energy management and reduced EMI, thanks to adjustable slew rate control of the output stage. This allows engineers to optimize switching behavior to meet specific electromagnetic compatibility (EMC) requirements without external components.
