Infineon BTS5233-2GS: High-Side Power Switch for Automotive and Industrial Applications

The demand for robust, efficient, and intelligent power switching solutions continues to grow across the automotive and industrial sectors. Addressing this need, the Infineon BTS5233-2GS stands out as a highly integrated dual-channel high-side power switch, engineered to deliver superior performance and reliability in demanding environments.

This device is part of Infineon's renowned Smart High-Side Switch portfolio, which is designed to replace discrete component solutions like relays and fuses. The BTS5233-2GS integrates two independent channels, each capable of driving resistive or inductive loads with a continuous current of up to 230 mA per channel. Its low standby current makes it particularly suitable for applications where energy efficiency is paramount, such as in always-on systems found in modern vehicles.

A key strength of the BTS5233-2GS lies in its comprehensive suite of embedded protection and diagnostic features. These are critical for ensuring system safety and longevity. Protections include load current limitation, which prevents damage from short circuits and overloads, overtemperature shutdown with a configurable latch-off behavior, and overvoltage protection (including load dump resilience). Furthermore, the device provides detailed diagnostic feedback to the microcontroller, such as open-load detection in both on and off states, and a proportional current sense (IS) pin for real-time load current monitoring.

The automotive-grade qualification of the BTS5233-2GS ensures it operates flawlessly under the harsh conditions typical of automotive applications, including wide temperature ranges and significant voltage transients. Its compact PG-DSO-14 package offers a space-saving solution without compromising on power or functionality.

Typical applications are diverse, ranging from automotive body electronics such as seat heaters, window lifters, and LED lighting control to industrial automation systems where reliable switching of solenoids, valves, and small motors is required.

ICGOODFIND: The Infineon BTS5233-2GS is a premier choice for designers seeking a reliable, feature-rich, and space-efficient dual-channel high-side switch. Its blend of robust integration, advanced protective functions, and detailed diagnostics makes it an optimal solution for enhancing the reliability and intelligence of 12V/24V DC power systems in vehicles and industrial machinery.
