Infineon BTS7008-2EPA: High-Current PROFET™ Smart High-Side Power Switch

In the realm of automotive and industrial electronics, robust and intelligent power management is critical. The Infineon BTS7008-2EPA stands out as a premier solution, representing a significant advancement in high-current switching technology. As part of Infineon's PROFET™ (Protected MOSFET) family of Smart High-Side Switches, this device is engineered to deliver superior performance, diagnostic capabilities, and protection in demanding applications.

Designed to handle high-load currents up to 45 A, the BTS7008-2EPA is an ideal choice for driving resistive, capacitive, and inductive loads. Common applications include driving heaters, motors, and solenoids, as well as managing power distribution in modules such as body control units, fuse boxes, and battery management systems. Its ability to directly interface with a microcontroller via a logic-level input simplifies design and reduces the need for additional components.

A key strength of this power switch is its integrated suite of protection features. These include protection against overcurrent, overtemperature, short-circuit, and overvoltage conditions (such as load dump). Furthermore, it features reverse battery protection up to -40 V, a critical requirement in the harsh automotive environment. The device’s sophisticated diagnostic feedback provides real-time information on load current (via a proportional current sense pin), output short to ground or battery, and overtemperature warnings. This enables predictive maintenance and enhances system reliability.

The BTS7008-2EPA is housed in a thermally and electrically enhanced PG-TO263-7 package, which ensures excellent power dissipation and allows for compact PCB design. Its very low typical on-state resistance (RDS(on)) of just 0.8 mΩ minimizes conduction losses, leading to higher efficiency and reduced heat generation.

ICGOOODFIND: The Infineon BTS7008-2EPA is a highly integrated, robust, and intelligent high-side switch that sets a high standard for power management. Its combination of high-current handling, comprehensive diagnostic and protection features, and exceptional efficiency makes it an indispensable component for designers building next-generation automotive and industrial systems.
