Infineon BTS5180-2EKA: A High-Current PROFET™ Smart High-Side Power Switch

In the realm of automotive and industrial electronics, robust and intelligent power management is paramount. The Infineon BTS5180-2EKA stands out as a premier solution, engineered to meet the demanding requirements of high-current load control. As part of Infineon's esteemed PROFET™ (Protected MOSFET) family, this smart high-side switch integrates advanced protection, diagnostics, and control features into a single, compact package, simplifying design and enhancing system reliability.

Unmatched Power Handling and Integration

The BTS5180-2EKA is designed to drive resistive or inductive loads with a continuous current capability of up to 180 mΩ typical on-state resistance, the device minimizes power losses, making it exceptionally efficient for high-current applications such as driving heaters, motors, or LEDs in harsh environments. Its integration of a vertical power MOSFET with a CMOS control chip exemplifies smart power technology, reducing the need for external components and saving valuable board space.

Advanced Protection and Diagnostic Features

A key strength of this PROFET™ switch is its comprehensive suite of embedded protective functions. It safeguards itself and the downstream system against:

Overload and Short-Circuit Conditions: The device features advanced current limiting and immediate shutdown in case of a short, followed by an automatic restart.

Overtemperature: An internal temperature sensor triggers a shutdown if the junction temperature exceeds a critical threshold, preventing thermal damage.

Overvoltage and Reverse Battery Protection: The chip can withstand negative voltages on the supply line, protecting against accidental reverse battery connection.

Furthermore, it provides precise diagnostic feedback to the microcontroller via a dedicated status pin. This enables real-time monitoring of load current (via analog proportional IS pin), open-load detection, and overtemperature warnings, facilitating predictive maintenance and enhancing system safety.

Designed for Automotive Excellence

Qualified according to AEC-Q100, the BTS5180-2EKA is built for the rigorous standards of the automotive industry. Its ability to operate reliably over a wide temperature range and its high immunity to electrical transients (as per ISO 7637) make it an ideal choice for body electronics modules, power distribution units, and other applications in vehicles where quality and durability are non-negotiable.
