AUIPS2041L

AUIPS2041L Description

The AUIPS2041L from Infineon Technologies is a low-side power switch designed for automotive-grade applications, integrating a single N-channel MOSFET with a 1:1 input-to-output ratio. This surface-mount (SOT-223) device delivers a maximum output current of 1.4A and supports load voltages up to 60V, making it suitable for robust power distribution in demanding environments. Although marked obsolete, its 100mOhm typical Rds(on) ensures efficient switching with minimal conduction losses. The IC operates without an external Vcc/Vdd supply, simplifying system design, and features built-in fault protection including fixed current limiting and over-temperature shutdown for enhanced reliability.

AUIPS2041L Features

• Automotive-Grade Compliance: Meets stringent automotive reliability standards.
• Low-Side Configuration: Ideal for grounding loads in 12V/24V systems.
• High Voltage Tolerance: Supports 60V load voltage for rugged applications.
• Integrated Protection: Current limiting and thermal shutdown prevent damage under fault conditions.
• Low Rds(on): 100mOhm typical resistance minimizes power dissipation.
• On/Off Interface: Simple control via logic-level input.
• MSL 1 (Unlimited): Suitable for extended storage without moisture concerns.

AUIPS2041L Applications

• Automotive Load Switching: Controls relays, lamps, or motors in body electronics, powertrains, and lighting systems.
• Industrial Power Management: Used in solenoid drivers, actuator controls, and low-voltage DC distribution.
• Protection Circuits: Safeguards battery-powered systems from overcurrent and overheating.
• Legacy System Maintenance: Replaces discrete MOSFET solutions in obsolete designs requiring compact, integrated switching.

Conclusion of AUIPS2041L

The AUIPS2041L excels in automotive and industrial environments where high-voltage tolerance, low conduction losses, and robust protection are critical. While obsolete, its combination of performance and reliability makes it a preferred choice for legacy designs or applications requiring proven technology. Engineers seeking compact, high-efficiency power switches for low-side configurations will find this IC a dependable solution, despite its discontinued status. For new designs, Infineon’s modern alternatives should be evaluated.
