Infineon BTS7200-2EPC: High-Current PROFET™ Smart High-Side Switch for Automotive and Industrial Applications

The demand for robust, intelligent power management solutions continues to grow across the automotive and industrial sectors. Addressing this need, Infineon Technologies introduces the BTS7200-2EPC, a dual-channel PROFET™ (Protected MOSFET) high-side switch engineered to deliver exceptional performance, reliability, and diagnostic capabilities in high-current applications.

This device integrates two independent channels, each capable of handling a continuous current of up to 20 A, making it ideal for driving demanding resistive or inductive loads. Typical applications include automotive body control modules—such as seat heaters, lighting systems, and power windows—as well as industrial solenoids, motor controllers, and power distribution units. Its high-current capability is paired with a very low typical on-state resistance (RDS(on)) of just 7 mΩ per channel, which minimizes power dissipation and improves overall system efficiency, reducing the need for complex heat sinking.

A key feature of the BTS7200-2EPC is its advanced diagnostic and protection suite. It provides comprehensive feedback to the microcontroller, including load current sense proportional to the output current, detection of open-load conditions, and flags for short-circuit, over-temperature, and over-voltage events. This level of intelligence is critical for designing fail-operational and safety-critical systems, ensuring operational security and simplifying maintenance.

The device is housed in a thermally enhanced, surface-mountable PG-TO263-7-31 package, offering excellent thermal performance for high-power operation. Furthermore, it is designed to withstand the harsh environments of its target applications, featuring ESD protection and high immunity to electrical transients, complying with stringent automotive qualifications.

ICGOOODFIND: The Infineon BTS7200-2EPC stands out as a superior solution for designers seeking a high-integration, intelligent power switch. Its combination of dual-channel high-current output, comprehensive diagnostic features, and robust protective functions makes it an excellent choice for enhancing the reliability and intelligence of next-generation automotive and industrial power systems.
