Infineon BTT6030-1EKA: High-Side Smart Switch for Robust Automotive and Industrial Applications

In the demanding arenas of automotive and industrial electronics, reliability, efficiency, and diagnostic capability are paramount. The Infineon BTT6030-1EKA stands out as a premier high-side smart switch engineered specifically to meet these rigorous challenges. As part of Infineon's PROFET™ (Protected MOSFET) family, this device integrates advanced power control and comprehensive protection features into a single, compact package, making it an ideal solution for driving a wide array of resistive, capacitive, and inductive loads.

Designed for Demanding Environments

The BTT6030-1EKA is built to excel in harsh operating conditions typical of automotive applications—such as driving lamps, solenoids, and motors—as well as in industrial control systems. Its robust construction ensures exceptional performance under high load currents, with a maximum continuous current rating of up to 28A. The device operates from a standard 12V battery supply, handling load voltages up to 40V, and is inherently protected against reverse battery connections.

Integrated Intelligence and Protection

A key strength of this smart switch is its high level of integration. It incorporates a vertical N-channel power MOSFET controlled by a charge pump, enabling efficient low-voltage control. More importantly, it bundles a suite of diagnostic and protection features that are critical for system safety and maintenance:

Advanced Diagnostic Feedback: Provides detailed status information on load current (via a proportional current sense pin), overtemperature, short circuits, and open-load conditions.

Comprehensive Protection: Includes safeguards against overload, short-circuit to ground or battery, overtemperature, and electrostatic discharge (ESD). This proactive protection enhances system longevity and prevents catastrophic failures.

Low Power Dissipation: Features a very low typical on-state resistance (RDS(on)), which minimizes heat generation and improves overall energy efficiency.

Ease of Design and Control

The BTT6030-1EKA simplifies design-in for engineers. It is controlled via a simple 3.3V/5V logic-compatible input, allowing for direct interfacing with microcontrollers without the need for additional level-shifting circuitry. Its status and diagnostic output pin provides a clear digital signal to the MCU, enabling real-time system monitoring and fault management. The device is offered in a space-saving, surface-mountable PG-TO263-7 package, which also provides excellent thermal performance.
