AUIPS2041R

AUIPS2041R Description

The AUIPS2041R from Infineon Technologies is a low-side power switch designed for automotive-grade applications, featuring a single N-channel MOSFET with a 1:1 input-to-output ratio. This surface-mount device operates without an external supply voltage, simplifying system design while delivering robust performance. With a maximum load voltage of 60V and 1.4A output current capability, it is optimized for general-purpose switching in demanding environments. The 100mOhm typical Rds(on) ensures efficient power handling, minimizing heat dissipation. Although marked as obsolete, its legacy design remains relevant for fault-tolerant systems requiring current limiting and over-temperature protection.

AUIPS2041R Features

• Automotive-Grade Reliability: Meets stringent automotive standards for durability and performance.
• Integrated Protection: Built-in fixed current limiting and thermal shutdown for enhanced safety.
• Low On-Resistance: 100mOhm Rds(on) reduces power losses and improves efficiency.
• Simplified Design: No external Vcc/Vdd required, reducing component count and board space.
• High Voltage Tolerance: Supports 60V load voltage, ideal for 12V/24V automotive systems.
• Robust Packaging: DPAK (TO-252) surface-mount package ensures mechanical stability and thermal performance.

AUIPS2041R Applications

• Automotive Load Control: Ideal for relay drivers, solenoid control, and LED lighting in vehicles.
• Industrial Switching: Suitable for low-side power distribution in factory automation and motor drives.
• Fault-Protected Systems: Used in battery management (BMS) and power sequencing where overcurrent/thermal protection is critical.
• Legacy Designs: Despite obsolescence, remains a fit for maintenance or long-lifecycle projects requiring proven reliability.

Conclusion of AUIPS2041R

The AUIPS2041R excels in automotive and industrial applications demanding high-voltage switching with integrated protection. Its low Rds(on), compact DPAK package, and no-supply-voltage operation make it a pragmatic choice for space-constrained, high-reliability designs. While newer alternatives may exist, its proven performance ensures continued relevance in legacy or niche systems. Engineers should evaluate replacement options but can leverage this device for cost-effective, fault-resistant solutions in harsh environments.
