MAX25614AATI/VY+

LED Driver IC Overview

The MAX25614AATI/VY+ is an automotive-grade LED driver IC designed for infrared LED and VCSEL applications in driver monitoring systems. It operates from a 4.5V to 36V input supply, delivering up to 10A output current with a maximum output voltage of 35V. The device utilizes a boost topology and supports I²C dimming control. Switching frequencies are selectable at 420kHz, 1MHz, 1.6MHz, or 2.1MHz. It features an internal switch and is housed in a 28-TQFN (5x5) package.

LED Driver IC Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Integrated high-current boost regulator for IR LEDs and VCSELs
• Digital control interface via I²C for precise dimming adjustment

LED Driver IC Applications

• Driver monitoring system (DMS) illumination
• Infrared LED driving for proximity sensing
• VCSEL driver circuits in automotive safety modules

LED Driver IC Procurement Notes

Verify the specific suffix 'AATI/VY+' against official Analog Devices documentation to confirm pinout and thermal pad configuration. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors. Ensure the component meets AEC-Q100 grade requirements for your specific automotive application environment.

LED Driver IC Selection Notes

Select this component when designing automotive driver monitoring systems requiring high-current IR LED or VCSEL drive capabilities. The boost topology is suitable for applications where the input voltage may drop below the required LED forward voltage. The I²C interface allows for dynamic brightness control and diagnostic feedback integration within the vehicle's network.

LED Driver IC Part Context

This part belongs to the MAX25614 series of high-current LED drivers optimized for automotive safety and monitoring applications. It is distinct from buck or SEPIC variants in the same family due to its specific boost-only architecture and I²C digital control interface, tailored for compact driver monitoring unit designs.
