Infineon BTS3408GXUMA2 High-Side Power Switch: Features and Application Overview
The Infineon BTS3408GXUMA2 is a state-of-the-art high-side power switch designed to deliver robust performance and enhanced protection for a wide range of automotive and industrial applications. As part of Infineon’s growing portfolio of intelligent power devices, this component integrates advanced functionalities that simplify design, increase reliability, and reduce system cost.
One of the standout features of the BTS3408GXUMA2 is its integrated protection mechanisms. The device includes over-current protection, over-temperature shutdown, and over-voltage clamp, ensuring safe operation under harsh conditions. It also features reverse battery protection up to -40V, making it particularly suitable for automotive environments where electrical transients are common.
The switch supports load current capability of up to 8.5A, with a very low typical on-state resistance (RDS(on)) of just 9 mΩ. This results in reduced conduction losses and improved energy efficiency, which is critical for battery-powered and energy-sensitive applications. Additionally, the device offers diagnostic feedback via a status output pin, enabling real-time fault detection and system monitoring.
A key advantage of the BTS3408GXUMA2 is its compatibility with microcontroller-driven systems. It accepts logic-level inputs, allowing direct control from GPIO pins of standard MCUs without requiring additional interface circuitry. This simplifies PCB layout and reduces the overall component count.
Typical applications include automotive power management systems such as LED lighting modules, motor control units, and solenoid drivers. It is also well-suited for industrial automation, including PLCs, actuator controls, and power distribution systems.
The Infineon BTS3408GXUMA2 stands out as a highly integrated and protected high-side switch, offering high current capability, comprehensive diagnostics, and robust performance for demanding applications in automotive and industrial sectors.
