AUIPS1051L

Power Distribution Switches, Load Drivers Overview

The AUIPS1051L is a low-side power switch manufactured by Infineon Technologies, formerly International Rectifier. It features a single N-channel output configured for surface-mount installation in an SOT-223 package with three pins. The device supports a maximum load voltage of 36V and delivers an output current of 1.1A. It operates within a temperature range of -40°C to +150°C TJ. Key protection mechanisms include fixed current limiting and overtemperature shutdown. The component is automotive-grade and complies with AEC-Q100 standards.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'L' against official Infineon documentation to confirm pinout and electrical characteristics. Ensure the selected variant matches the required SOT-223 package dimensions. Confirm AEC-Q100 certification status if automotive qualification is mandatory for the target application environment.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a robust, automotive-certified low-side switch is required for loads up to 36V. Consider the 1.1A output capability and integrated thermal protection for applications demanding high reliability. Verify that the SOT-223 footprint fits the PCB layout constraints and that the operating temperature range meets environmental requirements.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the IPS1051 family of low-side power switches. It shares functional similarities with other automotive-grade drivers but is distinct in its specific package type and electrical ratings. The 'A' prefix typically denotes automotive qualification, while 'L' specifies the particular package or revision variant within the product line.

Power Distribution Switches, Load Drivers Replacement Considerations

Check for direct substitutes such as the standard IPS1051 series variants. Verify compatibility with existing PCB footprints and ensure equivalent current handling and voltage ratings before substitution.
