Infineon BTS716GXUMA1: High-Current PROFET™ Smart High-Side Switch for Automotive Applications

The increasing complexity of automotive electronic systems demands robust, intelligent, and highly reliable power management solutions. The Infineon BTS716GXUMA1 stands out as a premier high-current PROFET™ (Protected MOSFET) smart high-side switch engineered specifically to meet these stringent automotive requirements. This device integrates two independent channels into a single package, providing a compact and efficient solution for driving high-current loads such as motors, heaters, and lamps.

A key strength of the BTS716GXUMA1 is its robust protection features and diagnostic capabilities. Each channel can handle a continuous current of up to 30A, making it suitable for the most demanding applications. It is housed in a thermally enhanced, space-saving PG-DSO-36 package, which ensures excellent power dissipation. The built-in protective functions include protection against overload, short-circuit, over-temperature, and over-voltage, safeguarding both the switch and the connected load from damage. Furthermore, its sophisticated diagnostic feedback provides crucial information on load current (via a proportional IS pin), open-load conditions, and overtemperature shutdowns, enabling predictive maintenance and enhanced system safety.

This PROFET™ switch is designed with the challenging automotive environment in mind. It offers exceptional resilience against electrostatic discharge (ESD) and features a very low standby current, which is critical for preserving battery life in always-connected vehicles. Its compatibility with microcontrollers is seamless due to its direct interface capability with 3.3V and 5V logic levels. The device also includes an active reverse battery protection mechanism, ensuring functionality even if the battery polarity is inadvertently reversed.

Typical applications are extensive, ranging from controlling body electronics modules, powertrain systems, to advanced driver-assistance systems (ADAS). Its dual-channel design allows it to manage two separate loads independently, simplifying board layout and reducing the total component count.

ICGOOFIND: The Infineon BTS716GXUMA1 PROFET™ smart high-side switch is an all-in-one power solution that combines high current handling, comprehensive integrated protection, and detailed diagnostic reporting. It is an optimal choice for automotive designers seeking to enhance system reliability, safety, and efficiency while reducing design complexity and time-to-market.
