Infineon BTS50085-1TMB: High-Current Smart High-Side Power Switch

In the world of advanced power management, the demand for robust, intelligent, and highly efficient switching solutions continues to grow across industries such as automotive, industrial automation, and consumer electronics. Addressing these needs, the Infineon BTS50085-1TMB stands out as a high-current smart high-side power switch, combining superior performance with integrated protection and diagnostic features.

This power switch is engineered to handle high-load currents up to 85 A, making it ideal for demanding applications like solenoid driving, motor control, and power distribution in 12 V and 24 V systems. Its low typical on-state resistance (RDS(on)) of just 0.5 mΩ ensures minimal power dissipation, leading to higher efficiency and reduced thermal stress, which is critical in space-constrained and thermally sensitive environments.

A key advantage of the BTS50085-1TMB is its integrated smart protection capabilities. It includes safeguards against overcurrent, overtemperature, short circuits, and overvoltage conditions. These features not only enhance system reliability but also contribute to longer operational life by preventing catastrophic failures. Additionally, the device offers diagnostic feedback such as current sense and status flag outputs, enabling real-time monitoring and control for predictive maintenance and system optimization.

The device is housed in a TOLL (TO-Leadless) package, which offers excellent thermal performance and a compact footprint. This makes it suitable for modern applications where board space is at a premium. Furthermore, its automotive-grade qualification ensures robustness under harsh operating conditions, complying with stringent industry standards.

With its combination of high current handling, efficiency, and intelligence, the Infineon BTS50085-1TMB provides a comprehensive solution for designers seeking to improve performance and reliability in high-power switching applications.
