Infineon BTS50080-1EGA: A High-Performance Smart High-Side Power Switch

In the realm of automotive, industrial, and consumer electronics, the efficient and reliable control of high currents is paramount. The Infineon BTS50080-1EGA stands out as a premier solution, embodying the pinnacle of smart power switch technology. This device is engineered to deliver robust performance, exceptional diagnostic capabilities, and superior integration, making it an ideal choice for a wide array of demanding applications.

As a smart high-side switch, the BTS50080-1EGA integrates a vertical power MOSFET with a charge pump, current and temperature monitoring, and comprehensive protection features into a single, compact PG-TO-263-7 package. Its core capability is to precisely switch and protect loads up to 80A. This high current-handling capacity is crucial for driving heavy-duty resistive, inductive, and capacitive loads such as motors, heaters, and power circuits with utmost reliability.

One of the most significant advantages of this device is its advanced diagnostic and protection features. It provides precise load current feedback via an analog proportional current sense (IS) pin, enabling real-time system monitoring without the need for external shunt resistors. Furthermore, it is equipped with a suite of built-in protections including overload protection (OL), short-circuit protection (SC), over-temperature shutdown (OTSD), and over-voltage clamp (OVC). These features not only safeguard the switch itself but also protect the microcontroller and the entire application from potential damage, thereby enhancing system longevity and safety.

The ProfiFET+ technology from Infineon underpins its exceptional performance. This technology ensures an extremely low typical on-state resistance (RDS(on)) of just 0.5 mΩ. This minimal resistance is a key contributor to its high efficiency, as it directly translates to reduced conduction losses and lower heat generation. The result is a cooler-running, more energy-efficient system that requires less thermal management.

Designed with the automotive industry's rigorous standards in mind, the BTS50080-1EGA is AQD-100 qualified, ensuring supreme quality and reliability for mission-critical applications. Its embedded control and diagnostic intelligence simplify design-in processes, reduce external component count, and lower the total system cost, making it a highly attractive solution for modern electronic architectures.

ICGOODFIND: The Infineon BTS50080-1EGA is a top-tier smart high-side power switch that sets a benchmark for performance and integration. Its combination of an 80A load rating, ultra-low RDS(on), and comprehensive diagnostic suite makes it an indispensable component for designers seeking to build robust, efficient, and intelligent power systems.
