Infineon BTS410E2: High-Side Power Switch for Robust Automotive and Industrial Applications

The demand for highly reliable, efficient, and compact power switching solutions continues to grow across automotive and industrial sectors. Addressing this need, Infineon Technologies introduces the BTS410E2, a smart high-side power switch engineered to deliver superior performance in demanding environments. This device integrates advanced protection features, diagnostic capabilities, and robust switching functionality into a single package, making it an ideal choice for applications where durability and intelligence are critical.

Key Features and Technical Advantages

At its core, the BTS410E2 is designed to switch resistive or inductive loads with high accuracy and minimal power loss. It operates with a wide voltage range from 5.5 V to 28 V, covering standard automotive electrical systems (12 V) and industrial DC supplies (24 V). The device boasts an extremely low standby current, which is crucial for battery-powered applications, helping to extend operational life and reduce energy consumption.

One of the standout attributes of the BTS410E2 is its comprehensive suite of integrated protection functions. These include over-load protection, short-circuit protection, over-temperature shutdown, and over-voltage clamp. The built-in active reverse polarity protection ensures that the device remains undamaged even if the battery connections are reversed—a common risk in automotive environments. Moreover, its current limitation feature safeguards both the switch and the load during fault conditions, enhancing system reliability.

Diagnostic and Control Capabilities

The BTS410E2 provides detailed diagnostic feedback through its status output pin, which indicates various operating states such as normal operation, over-current, or over-temperature conditions. This enables real-time monitoring and swift system responses to faults, reducing downtime and maintenance costs. The device can be controlled via a logic-level input compatible with microcontrollers, facilitating easy integration into digital control systems.

Robustness for Harsh Environments

Constructed using Infineon’s proven SMART technology, the BTS410E2 is housed in a TO-252-5 (DPAK) package that offers excellent thermal performance and power dissipation. It is designed to withstand the rigors of automotive and industrial applications, including high humidity, mechanical stress, and temperature fluctuations. The device complies with AEC-Q100 standards for automotive quality, ensuring long-term reliability under the most challenging conditions.

Application Areas

Typical applications for the BTS410E2 include:

- Automotive systems: driving lamps, solenoids, motors, and heaters.

- Industrial automation: controlling actuators, valves, and small DC motors.

- Power distribution units: managing secondary power rails safely.

- Consumer and commercial equipment: where robust and intelligent switching is required.
