AUIR3314S

AUIR3314S Description

The AUIR3314S by Infineon Technologies is a high-side power switch designed for automotive and general-purpose load driving applications. This N-channel MOSFET-based driver integrates a 1:1 input-to-output ratio and operates within a 6V to 32V load voltage range, making it suitable for robust power distribution systems. With a maximum output current of 18A and an exceptionally low Rds(on) of 9mΩ (typical), it minimizes power losses and enhances efficiency. The device features adjustable current limiting and over-temperature protection, ensuring reliable operation under demanding conditions. Packaged in a D2PAK surface-mount form factor, it is optimized for high-power PCB designs.

AUIR3314S Features

• High-Side Configuration: Simplifies circuit design by eliminating the need for an external supply (Vcc/Vdd).
• Automotive-Grade Reliability: Complies with stringent automotive standards for durability and performance.
• Low On-Resistance: 9mΩ Rds(on) reduces conduction losses, improving thermal management.
• Integrated Protections: Adjustable current limiting and thermal shutdown enhance system safety.
