Infineon BTS7080-2EPA High-Current PROFET™ Smart Switch for Automotive Applications

The Infineon BTS7080-2EPA is a state-of-the-art high-current PROFET™ (Protected MOSFET) smart switch engineered specifically for the rigorous demands of automotive electronic systems. As a robust and highly integrated power management solution, it is designed to drive a wide range of resistive, capacitive, and inductive loads—such as motors, heaters, and lamps—with exceptional reliability and diagnostic capabilities.

This device features two independent channels, each capable of handling a continuous current of up to 7.5 A. A key advantage of the BTS7080-2EPA is its very low standby current, which is critical for modern vehicles where minimizing power consumption in sleep mode is essential to prevent battery drain. It operates from a 12 V battery supply and is fully compatible with standard microcontroller interfaces, making it easy to integrate into existing automotive architectures.

The "smart" functionality is a cornerstone of its design. The PROFET™ switch includes comprehensive embedded protection mechanisms against overload, short-circuit, over-temperature, and over-voltage conditions. Furthermore, it provides precise diagnostic feedback to the host microcontroller, including status on open-load, overtemperature pre-warning, and current sense proportional to the load current. This enables predictive maintenance and enhances system safety and reliability.

Housed in a compact and robust PG-DSO-14 EP package, the device offers excellent thermal performance and is built to withstand the harsh environmental conditions typical in automotive applications, including significant temperature fluctuations and high levels of electrical noise. Its high level of integration reduces the need for external components, saving valuable board space and lowering the total system cost.

In summary, the BTS7080-2EPA represents a powerful and intelligent solution for managing high-current loads in automotive body electronics modules, power distribution units, and other applications requiring robust and diagnosable power switching.
