Infineon BTS436L2G: High-Performance Smart High-Side Power Switch for Automotive and Industrial Applications

The demand for robust, efficient, and intelligent power switching solutions continues to grow across automotive and industrial sectors. Addressing this need, Infineon Technologies introduces the BTS436L2G, a smart high-side power switch engineered to deliver superior performance, reliability, and diagnostic capabilities in demanding environments.

Designed with advanced semiconductor technology, the BTS436L2G integrates a low on-state resistance (RDS(on)) of typically 7.5 mΩ, which significantly reduces conduction losses and minimizes heat generation. This feature is critical for improving energy efficiency and enabling high current handling up to 30 A, making it suitable for applications such as automotive body control modules, motor drives, solenoid control, and industrial automation systems.

A key strength of the BTS436L2G lies in its comprehensive suite of protection and diagnostic functions. It includes overload protection, short-circuit protection, over-temperature shutdown, and over-voltage clamp, ensuring safe operation under fault conditions. Additionally, the device offers precise current sensing and status feedback signals, allowing system controllers to monitor load conditions in real-time and implement predictive maintenance strategies.

The device is housed in a compact, surface-mount PG-TO-263-7 package, which offers excellent thermal performance and facilitates space-efficient PCB design. Its automotive-grade qualification (AEC-Q100 compliant) and robust construction make it ideal for use in harsh environments, where reliability under extreme temperatures and voltage fluctuations is paramount.

Furthermore, the BTS436L2G supports reverse battery protection and features very low standby current, enhancing its suitability for battery-powered applications. Its compatibility with microcontrollers and logic-level signals simplifies system integration, reducing both design complexity and time-to-market.

ICGOODFIND Summary:

The Infineon BTS436L2G stands out as a high-efficiency, smart high-side switch that combines low power dissipation, advanced protection mechanisms, and diagnostic intelligence.
