Infineon BTS5016-1EKB: A High-Current Smart High-Side Power Switch

The Infineon BTS5016-1EKB represents a significant advancement in the field of intelligent power switching, designed to meet the rigorous demands of modern automotive and industrial applications. As a smart high-side power switch, it integrates a multitude of features into a single, robust package, offering designers a compact and highly reliable solution for controlling high-current loads.

Engineered for high-current capability, the device can handle a continuous current of up to 140 mA in its linear operating mode and is capable of managing much higher pulsed loads, making it ideal for driving motors, heaters, solenoids, and lamps. Its core is a vertical N-channel power MOSFET with an extremely low typical on-state resistance (RDS(on)) of just 6.5 mΩ. This exceptional efficiency minimizes power losses and heat generation, which is critical for enhancing overall system reliability and thermal performance.

Beyond mere switching, the "smart" functionality is what truly sets the BTS5016-1EKB apart. It incorporates a comprehensive suite of diagnostic and protection features that safeguard both the switch and the connected load. These include protection against overload, short-circuit, over-temperature, and over-voltage conditions. Furthermore, it provides precise current sense and proportional load current feedback to the microcontroller, enabling real-time system monitoring and control without the need for external shunt resistors. The device also offers advanced diagnostic capabilities such as open-load detection in both on and off states.

Housed in a space-saving, surface-mountable TO-263-7 (D2PAK) package, the switch is designed for excellent thermal conductivity, allowing heat to be efficiently dissipated into the PCB. Its automotive-grade qualification ensures operation under the harsh conditions of the automotive environment, including resistance to transients and wide temperature ranges.
