Infineon BTS4175SGAXUMA1 Smart High-Side Power Switch: Features, Applications, and Benefits

The Infineon BTS4175SGAXUMA1 is a state-of-the-art smart high-side power switch designed to deliver robust performance and intelligent control in a wide range of power management applications. As part of Infineon’s PROFET™+ 2 family, this device integrates advanced protection, diagnostic capabilities, and high efficiency in a compact package, making it a preferred solution for automotive, industrial, and consumer electronics.

Key Features

One of the standout attributes of the BTS4175SGAXUMA1 is its high current handling capacity, supporting up to 17 A continuous current. It operates with a low on-state resistance (RDS(on)), typically 25 mΩ, which minimizes power losses and improves thermal performance. The device also features a wide operating voltage range from 5.5 V to 28 V, catering to both 12 V and 24 V systems.

The integration of comprehensive protection functions ensures system reliability. These include overcurrent protection, overtemperature shutdown, short-circuit protection, and load dump resilience. Additionally, the device offers diagnostic feedback via a status output pin, which provides real-time information on fault conditions such as open-load, overtemperature, or short-circuit events.

Applications

The BTS4175SGAXUMA1 is widely used in automotive systems, including power distribution units, body control modules, and seat/heating controls. Its ability to withstand harsh automotive environments—coupled with its AEC-Q100 qualification—makes it ideal for in-vehicle applications.

Beyond automotive, this power switch is also suitable for industrial automation systems, such as solenoid and valve control, as well as consumer electronics requiring safe and efficient power management. Its diagnostic capabilities are particularly valuable in applications where system monitoring and maintenance are critical.

Benefits

Designers benefit from the device’s ease of integration due to its small PG-SSOP-14-22 package and minimal external component requirements. The combination of high efficiency and thermal robustness reduces the need for heat sinks, saving both space and cost. Moreover, its advanced diagnostic features enhance system safety and simplify troubleshooting, leading to lower development time and improved end-product reliability.
