Infineon BTS7741G High-Current PROFET™ Smart Switch for Automotive and Industrial Applications

The Infineon BTS7741G is a state-of-the-art high-current PROFET™ (Protected MOSFET) smart switch engineered to meet the rigorous demands of automotive and industrial applications. Designed to deliver superior performance, reliability, and diagnostic capabilities, this device integrates advanced protection features and a robust power stage into a compact package, making it an ideal solution for driving resistive, capacitive, and inductive loads.

At the core of the BTS7741G is a vertical N-channel power MOSFET with an extremely low typical on-state resistance (RDS(on)), which minimizes power dissipation and improves overall system efficiency. It supports a continuous current of up to 30 A per channel (with a maximum peak current handling capability) and operates within a wide voltage range, making it suitable for 12 V and 24 V automotive systems, as well as industrial power networks.

One of the standout features of the BTS7741G is its comprehensive suite of integrated protection and diagnostic functions. These include protection against overload, short-circuit, over-temperature, and over-voltage conditions, ensuring safe operation even in harsh environments. The device also provides detailed feedback via a current sense pin that delivers a proportional current output, enabling precise load current monitoring without additional external components.

The module is designed with automotive-grade reliability, adhering to AEC-Q100 standards, and is capable of withstanding extreme temperatures and electrical transients typical in automotive applications such as engine control units, power distribution boxes, and motor drive systems. In industrial contexts, it is well-suited for PLC outputs, actuator controls, and solenoid drivers.

Housed in a thermally enhanced PG-TO-263 package, the BTS7741G offers excellent thermal performance, which is critical for high-current switching applications. Its reverse battery protection and ESD robustness further enhance system durability.
