Infineon BTS3405GXUMA1: High-Performance Smart High-Side Power Switch

Modern electronic systems demand robust, efficient, and intelligent power management solutions. The Infineon BTS3405GXUMA1 stands out as a state-of-the-art smart high-side power switch designed to meet these rigorous requirements. Integrating advanced protection features, diagnostic capabilities, and high efficiency into a compact package, this device is engineered for a wide range of automotive, industrial, and consumer applications where reliability is paramount.

Constructed using Infineon’s proven SMART7 technology, the BTS3405GXUMA1 delivers exceptional load control with a continuous current capability of up to 1.7 A. Its low on-state resistance (RDS(on)) ensures minimal power dissipation, leading to higher system efficiency and reduced thermal stress. The device operates from a standard 12 V supply and is housed in a space-saving PG-TSDSO-14 package, making it suitable for PCB designs with strict size constraints.

A key strength of this power switch is its comprehensive suite of integrated protection and diagnostic functions. These include protection against overload, short-circuit, over-temperature, and over-voltage conditions, significantly enhancing system durability. The built-in diagnostic feedback pin provides real-time status information such as open-load detection, short-circuit indication, and overtemperature warnings, enabling predictive maintenance and quicker fault resolution.

The BTS3405GXUMA1 is particularly well-suited for automotive applications, including body control modules, power seat controllers, and lighting systems, where it must perform reliably under harsh environmental conditions. Its high electrostatic discharge (ESD) protection and reverse battery protection further ensure safe operation in demanding scenarios.

ICGOOODFIND: The Infineon BTS3405GXUMA1 is a highly integrated and reliable high-side switch that combines power efficiency, robust protection mechanisms, and precise diagnostic intelligence—making it an optimal solution for modern power switching applications.
