BTF6070-2ERV: Infineon's High-Current Smart High-Side Power Switch

In the realm of automotive and industrial electronics, the demand for robust, intelligent, and highly efficient power switching solutions is paramount. Addressing this need, Infineon Technologies introduces the BTF6070-2ERV, a state-of-the-art smart high-side power switch engineered to deliver exceptional performance and reliability in the most demanding applications.

This device is a standout member of Infineon's proven PROFET™ (Protected MOSFET) family. Its core function is to serve as a solid-state switch, controlled by a low-power microcontroller signal, to manage the power supply to a load—such as a motor, solenoid, lamp, or heater—located between its output and ground (hence "high-side"). What truly defines the BTF6070-2ERV is its integration of a high-current capability with a comprehensive suite of built-in protection and diagnostic features. It can continuously handle currents up to 37A, with a very low typical on-state resistance (RDS(on)) of just 5.5 mΩ, which translates to minimal power loss and superior energy efficiency.

The "smart" in its title is justified by an impressive array of embedded protective circuits. These include protection against overload, short-circuit, over-temperature, and over-voltage conditions. In the event of a fault, the device automatically limits the output current or shuts down completely, safeguarding both itself and the connected load. Crucially, it provides immediate feedback to the host microcontroller through a dedicated status pin, flagging issues like open-load (both pre- and post-operation), short-to-ground, or overtemperature. This diagnostic capability is vital for designing predictive maintenance systems and ensuring functional safety, a critical requirement in automotive systems adhering to standards like ISO 26262.

Housed in a compact, space-saving PG-TO263-7 package, the BTF6070-2ERV is particularly suited for challenging 24V automotive environments, commonly found in commercial vehicles, agricultural machinery, and heavy-duty equipment. It is also ideal for 24V industrial automation systems. Its ability to withstand high in-rush currents makes it perfect for driving inductive loads. Furthermore, its reverse battery protection (-40V) and load-dump resilience (up to 45V) ensure unwavering operation despite voltage spikes and incorrect jumper-start scenarios.

ICGOOODFIND: The Infineon BTF6070-2ERV is a powerhouse of integration, combining a high-current switch with advanced intelligence. Its exceptional blend of high power handling, robust integrated protection, and precise diagnostic feedback makes it an indispensable component for engineers designing reliable and safe electronic systems in automotive and industrial sectors.
