Infineon BTS141 Smart High-Side Power Switch: Features and Applications

The Infineon BTS141 is a versatile smart high-side power switch designed for a wide range of automotive and industrial applications. As part of Infineon’s PROFET™ (Protected MOSFET) family, this device integrates advanced protection, monitoring, and control features into a compact package, making it an ideal solution for driving resistive, inductive, and capacitive loads with high reliability.

Key Features of the BTS141

One of the standout characteristics of the BTS141 is its integrated protection functions. These include overcurrent protection, which safeguards the switch and load from excessive current, and overtemperature shutdown, which prevents thermal damage. Additionally, the device features short-circuit protection and overvoltage clamping, enhancing system durability under fault conditions.

The BTS141 also offers diagnostic feedback via a status pin, providing real-time information on operational states such as normal operation, open load, or overtemperature conditions. This feature simplifies system monitoring and fault detection, reducing development time and improving maintenance efficiency.

With a low standby current and high efficiency, the BTS141 is optimized for energy-sensitive applications. Its reverse battery protection ensures safe operation even if the power supply connections are reversed, a critical requirement in automotive environments.

Applications

The BTS141 is widely used in automotive systems, including power window controls, seat adjusters, and lighting modules. Its robustness and diagnostic capabilities make it suitable for body control modules, where reliability and fault reporting are essential.

In industrial applications, the device drives solenoids, valves, relays, and small motors. Its ability to handle inrush currents and inductive loads makes it a preferred choice for automation and control systems.
