The Infineon BTS117TC is a state-of-the-art smart high-side power switch designed to deliver robust performance, enhanced diagnostic capabilities, and superior integration for modern electronic systems. As part of Infineon’s PROFET™ (Protected MOSFET) family of products, this device is engineered to meet the rigorous demands of automotive and industrial applications, offering a blend of power efficiency, reliability, and intelligent control.
Key Features
One of the standout attributes of the BTS117TC is its integrated protection and diagnostic functions. The device incorporates safeguards against overload, short-circuit, over-temperature, and over-voltage conditions, ensuring operational safety and longevity. Its reverse battery protection feature further enhances system durability, making it ideal for harsh environments like automotive power networks.
The BTS117TC also features a low standby current and efficient power management, which are critical for battery-dependent applications. With a low on-state resistance (RDS(on)), it minimizes conduction losses, thereby improving overall energy efficiency. The device supports PWM (Pulse Width Modulation) capability, allowing for precise control of connected loads such as motors, lamps, or solenoids.
Additionally, the switch provides diagnostic feedback via a status pin, which delivers real-time information on fault conditions such as open-load or overtemperature events. This facilitates proactive system maintenance and troubleshooting.
Applications
Thanks to its rugged design and versatile characteristics, the BTS117TC is widely used across multiple sectors. In the automotive industry, it is commonly employed in body control modules, power seat controllers, window lift systems, and lighting control units. Its ability to handle high inrush currents makes it suitable for driving inductive loads.

Beyond automotive applications, this power switch is also used in industrial automation systems, including PLCs (Programmable Logic Controllers), solenoid and valve controls, and small motor drives. Its compatibility with microcontrollers and diagnostic capabilities make it a preferred choice for smart manufacturing and IoT-enabled devices.
Benefits
The BTS117TC offers several significant benefits. Its high level of integration reduces the need for external components, simplifying PCB design and lowering overall system cost. The device’s built-in protection mechanisms increase system reliability and reduce the risk of failure in demanding conditions.
Moreover, its energy-efficient operation helps extend battery life in portable and mobile applications. The diagnostic features not only enhance functional safety but also streamline development and debugging processes, shortening time-to-market for end products.
