Infineon BTS7710G: High-Current PROFET™ Smart Switch for Automotive Applications
The increasing complexity of automotive electrical systems demands robust, intelligent, and highly reliable high-current switching solutions. Addressing this need, the Infineon BTS7710G stands out as a premier PROFET™ (Protected MOSFET) smart high-side power switch, engineered to drive the most demanding loads in the modern vehicle.
Designed to control a wide range of resistive or inductive loads, the BTS7710G is capable of handling continuous currents up to 22 A from a 12 V battery. Its primary application lies in driving high-power actuators, such as heating elements, motors, and solenoid valves, which are ubiquitous in body control modules, powertrain systems, and comfort applications.
The "smart" in its designation refers to a comprehensive suite of integrated protection and diagnostic features that safeguard both the switch and the broader system. Key protections include protection against overload, short-circuit, and overtemperature conditions. Furthermore, the device features advanced diagnostics, providing precise feedback to the microcontroller on status, current consumption (via a proportional current sense pin IS), and fault conditions like open-load detection both in on and off-state. This level of intelligence is critical for functional safety (ISO 26262) and enables predictive maintenance, reducing warranty costs.
Built on Infineon's proven SMIF (Smart MOSFET) technology, the BTS7710G is housed in a compact, space-saving PG-TO263-7 package that offers an excellent power-to-size ratio. Its very low typical on-state resistance (RDS(on)) ensures minimal power dissipation, leading to higher system efficiency and reduced thermal management requirements. This combination of high performance, robustness, and diagnostic capabilities makes it an ideal choice for 12 V and 24 V automotive systems, ensuring reliable operation under harsh environmental conditions.

The Infineon BTS7710G is a high-integration PROFET™ solution that delivers robust high-current switching, superior diagnostic intelligence, and comprehensive protection, making it a cornerstone for next-generation automotive power management.
