Infineon BTS117: A High-Performance Single Channel Smart High-Side Power Switch

In the realm of power management and control, efficiency, reliability, and integration are paramount. The Infineon BTS117 stands out as a premier solution, embodying these critical attributes in a robust and compact package. As a single-channel smart high-side power switch, it is engineered to deliver superior performance in a wide array of automotive and industrial applications, from driving resistive, capacitive, and inductive loads to serving as a vital interface between microcontrollers and power-hungry components.

The core of the BTS117's functionality lies in its advanced protective features and diagnostic capabilities. Integrated onto a single chip, this device combines a vertical power MOSFET with smart control logic. This integration allows for precise control and monitoring of load currents, enabling systems to operate with heightened intelligence and safety. Key protective functions include overload protection, short-circuit clamping, and overtemperature shutdown, which collectively safeguard both the switch itself and the connected load from potential damage under fault conditions. Furthermore, its reverse battery protection ensures operational integrity even if the power supply connections are inadvertently reversed—a critical feature for automotive environments.

A significant advantage of the BTS117 is its extremely low standby current consumption, making it an ideal choice for battery-powered applications where energy efficiency is crucial. The device operates with a wide supply voltage range, typically from 5.5V to 28V, providing flexibility for various system designs. Its efficient switching characteristics minimize power losses, contributing to cooler operation and improved overall system reliability.

The diagnostic feedback pin offers real-time status information, such as indicating an open load condition or the occurrence of a fault. This proactive diagnostic capability allows for predictive maintenance and quicker troubleshooting, reducing system downtime and enhancing operational safety.
