Infineon BTS740S: High-Current PROFET™ Smart High-Side Power Switch

In modern automotive and industrial electronics, robust and intelligent power management is critical. The Infineon BTS740S, part of the PROFET™ (Protected MOSFET) family of smart high-side power switches, stands out as a high-performance solution designed to control and protect high-current loads with exceptional precision and reliability.

The BTS740S integrates four independent channels, each capable of handling a continuous current of up to 7 A per channel, making it ideal for driving high-power applications such as solenoids, valves, motors, and lighting systems. Its advanced protective features ensure safe operation under various fault conditions, including overload protection, short-circuit shutdown, and overtemperature protection. Additionally, the device offers diagnostic feedback through a current sense pin, enabling real-time monitoring of load status—essential for predictive maintenance and system diagnostics.

Built with Infineon’s proprietary SMART technology, the BTS740S also provides enhanced ESD robustness and undervoltage lockout, ensuring stability in harsh electrical environments. Its efficient thermal design minimizes power dissipation, contributing to higher system reliability and longevity.
