Infineon BTS716GBXUMA1: High-Current PROFET™ Smart High-Side Power Switch for Automotive Applications

The increasing complexity of automotive electronic systems demands robust, intelligent, and highly reliable power management solutions. The Infineon BTS716GBXUMA1 stands out as a premier device in this domain, a high-current PROFET™ (Protected MOSFET) smart high-side power switch engineered specifically for the rigorous demands of automotive applications.

This device integrates two 7mΩ typical RDS(on) channels, allowing it to handle high-current loads up to 30A per channel with exceptional efficiency, minimizing power dissipation and thermal stress. Its primary role is to serve as a digital interface between a microcontroller (MCU) and a powerful load, such as resistive, capacitive, or inductive actuators in body electronics modules. This includes driving heating elements, powertrain systems, and high-performance lighting.

A key feature of the BTS716GBXUMA1 is its comprehensive suite of embedded protection and diagnostic functions. It provides robust safety mechanisms including protection against over-load, short-circuit, over-temperature, and over-voltage conditions. Crucially, its current sense diagnostic output offers a proportional current mirror signal (IS) for real-time load monitoring. This enables the detection of open-load conditions, short circuits, and even overtemperature warnings, allowing the system to take preemptive action before a fault becomes critical. The device also features reverse battery protection up to -40V, a vital requirement in the unpredictable automotive electrical environment.

Housed in a space-saving PG-TSDSO-14 exposed clip package, the component is designed for optimal thermal performance, efficiently transferring heat to the PCB to maintain stability under high load conditions. Its automotive-grade qualification ensures reliability and longevity, meeting the stringent AEC-Q100 standard.

ICGOOODFIND: The Infineon BTS716GBXUMA1 is an exemplary smart high-side switch that combines high-current handling, superior integration, and advanced diagnostic capabilities. It significantly enhances system reliability, simplifies design, and provides critical fault feedback, making it an ideal solution for modern automotive power distribution systems.
