Infineon BTS5016-2EKA: High-Current PROFET™ Smart Switch for Automotive Applications

The increasing complexity of automotive electrical systems demands robust, intelligent, and highly reliable switching solutions. Addressing this need, the Infineon BTS5016-2EKA stands out as a high-performance, fully protected high-side power switch from Infineon's esteemed PROFET™ (Protected MOSFET) family. This device is engineered specifically for the rigorous demands of the automotive environment, offering a powerful and intelligent solution for driving a wide array of resistive and inductive loads.

At its core, the BTS5016-2EKA is a single-channel smart switch capable of handling continuous currents up to 16 A. It integrates a vertical power MOSFET with a charge pump, essential for robust gate driving, alongside comprehensive protection and diagnostic features into a single, compact PG-TO263-7 package. This high level of integration simplifies board design, saves space, and enhances overall system reliability.

A key strength of this PROFET™ device is its comprehensive suite of embedded protection and diagnostic functions. These features are critical for ensuring safe operation and facilitating predictive maintenance in automotive applications. They include protection against overload, short-circuit, and overtemperature conditions. The device also features an advanced current sense pin that provides a proportional measurement of the load current with high accuracy. This is invaluable for real-time load monitoring, diagnosing faults like open loads or lamp outages, and eliminating the need for an external shunt resistor. Furthermore, the device offers protection against reverse battery and electrostatic discharge (ESD), making it exceptionally robust.

The BTS5016-2EKA is controlled via a standard 3.3 V/5 V logic-compatible input, allowing for direct interfacing with microcontrollers. Its very low standby current makes it ideal for always-on systems common in modern vehicles. Typical applications are diverse and critical, including:

Driving various lighting systems (headlights, LED modules, fog lamps).

Controlling DC motors in power seats, window lifters, and sunroofs.

Managing heating elements such as seat or steering wheel heaters.

Switching solenoids and relays.

In summary, the Infineon BTS5016-2EKA exemplifies the evolution of power switching, moving from a simple component to a smart system-level solution. It empowers designers to build safer, more efficient, and more diagnostic-capable automotive electronic control units (ECUs).

ICGOODFIND: The Infineon BTS5016-2EKA is a premier high-current PROFET™ smart switch that delivers exceptional robustness and integrated diagnostics for 12 V automotive systems. Its combination of high power handling, comprehensive protection features, and accurate load current monitoring makes it an optimal choice for designers seeking to enhance the performance, safety, and intelligence of their automotive power distribution modules.
