AUIPS6041GTR: High-Side Switch with Advanced Protection and Diagnostic Features

In the realm of automotive and industrial electronics, robust power management is paramount. The AUIPS6041GTR from Infineon Technologies stands out as a high-side power switch engineered to meet these demanding requirements. This intelligent device integrates a sophisticated array of protection and diagnostic features, making it an ideal solution for driving resistive, capacitive, and inductive loads such as solenoids, valves, motors, and lamps.

The core of the AUIPS6041GTR is a single-channel, N-channel power MOSFET controlled via a logic-level input. Its high-side configuration simplifies design by placing the switch between the supply and the load, reducing wiring complexity and enhancing system safety. A key advantage is its extremely low standby current, which is critical for battery-sensitive automotive applications.

What truly distinguishes this IC is its comprehensive suite of integrated safeguards. It features robust over-current protection with precise current limiting, shielding both the switch and the load from damage during fault conditions. The built-in over-temperature protection automatically disables the output if the junction temperature exceeds a safe threshold, reactivating only after the device has cooled down. Furthermore, it is designed to withstand load-dump and reverse battery conditions up to -40V, a common hazard in automotive environments, eliminating the need for additional external protection components.

Beyond protection, the AUIPS6041GTR provides critical diagnostic feedback to the microcontroller. An open-drain fault report pin signals various error states, including over-current, over-temperature, and open-load conditions. This allows for proactive system management and maintenance, significantly enhancing reliability. The device also detects an open load both in the on-state and off-state, ensuring full operational awareness.

Housed in a compact, surface-mount TO-263 package, the AUIPS6041GTR offers high power density and efficient thermal performance. Its combination of durability, intelligence, and integration makes it a cornerstone for designing advanced driver systems in body control modules, powertrain systems, and industrial automation.
