Infineon BTS5020-2E: High-Current PROFET™ Smart Switch for Automotive Applications

The demand for robust, intelligent, and highly efficient power management solutions is continuously growing in the automotive industry. Addressing this need, Infineon Technologies introduces the BTS5020-2E, a standout member of its PROFET™ (Protected MOSFET) family of smart high-side switches. This device is engineered to deliver exceptional performance and reliability for a wide array of demanding automotive applications, from powertrain systems to comfort and convenience modules.

Engineered for high-current switching, the BTS5020-2E boasts a continuous current rating of up to 20 A per channel. This makes it an ideal solution for driving heavy loads such as heating elements, motors, and LED lighting systems. Its dual-channel design allows for the control of two independent loads with a single, compact package, contributing to reduced board space and simplified system architecture.

A key hallmark of the PROFET™ series is its integrated protection features, and the BTS5020-2E excels in this regard. It incorporates a comprehensive suite of safeguards designed to ensure operational integrity in the harsh automotive environment. These include protection against over-load, short-circuit, over-temperature, and over-voltage conditions. The device also features advanced diagnostic capabilities, providing feedback to the microcontroller on status, current consumption, and fault conditions. This enables predictive maintenance and enhances overall system safety.

Furthermore, the switch is designed for very low power dissipation, thanks to its low typical on-state resistance (RDS(on)) of just 7 mΩ per channel. This high efficiency minimizes heat generation, reduces the need for complex cooling mechanisms, and contributes to lower energy consumption—a critical factor in modern vehicles.

Fully qualified for the rigorous AEC-Q100 automotive standard, the BTS5020-2E guarantees high quality and long-term reliability under extreme temperatures and voltage fluctuations. Its SPI interface allows for precise digital control and detailed diagnostics, making it a truly smart solution for next-generation automotive electronic systems.
