Infineon BTS3134D: High-Performance Smart High-Side Power Switch

The Infineon BTS3134D represents a state-of-the-art smart high-side power switch engineered to meet the rigorous demands of modern automotive and industrial applications. Combining robust power handling with advanced diagnostic and protection features, this device sets a high standard for reliability, efficiency, and system integration.

Designed to control resistive, capacitive, and inductive loads, the BTS3134D integrates a vertical power MOSFET with a charge pump, current and temperature monitoring, and extensive protection circuitry into a single compact package. Its ability to handle high inrush currents—typical when driving lamps, motors, or solenoids—makes it exceptionally versatile. The device supports a continuous current of up to 0.7 A with very low typical on-state resistance (RDS(on)), ensuring minimal power dissipation and high energy efficiency.

A key strength of the BTS3134D is its comprehensive suite of embedded protection features. These include protection against overloads, short circuits, over-temperature, and over-voltage conditions, significantly enhancing system durability. The built-in diagnostic capabilities provide real-time feedback on operational status, including open-load detection both in on and off states, which is critical for functional safety and predictive maintenance.

Furthermore, the device is designed for low electromagnetic interference (EMI), making it suitable for noise-sensitive environments. Its compatibility with microcontrollers via a standard logic-level input simplifies interface design, while the green product qualification and adherence to AEC-Q101 standards ensure reliability for automotive applications.
