MAX16822AASA/V+T

LED Driver IC Overview

The MAX16822AASA/V+T is a high-brightness LED driver IC from Analog Devices/Maxim Integrated, designed for automotive and general illumination. It operates as a step-down constant-current regulator with an integrated MOSFET and high-side current sense. The device supports an input voltage range of 6V to 65V and delivers up to 350mA output current per channel. It features a fixed switching frequency of 2MHz and supports PWM dimming. Packaged in an 8-SOIC (0.154" width) case, it is suitable for applications requiring compact, efficient LED control solutions.

LED Driver IC Feature Summary

• Integrates a power MOSFET and high-side current sensing for simplified design
• Supports pulse-width modulation (PWM) dimming for brightness control
• Operates at a fixed 2MHz switching frequency to minimize external component size

LED Driver IC Applications

• Automotive interior lighting
• Automotive exterior lighting
• Architectural lighting
• LED bulbs

LED Driver IC Procurement Notes

Verify the specific suffix 'V' indicates automotive qualification or variant specifications against the official datasheet. Confirm package dimensions match the 8-SOIC (0.154 inch width) requirement. Ensure compatibility with the 6V to 65V input range and 350mA current limit for the target application. Check for RoHS compliance status if required by project standards.

LED Driver IC Selection Notes

Select this component for designs requiring a single-channel, high-voltage LED driver with integrated power switching. It is appropriate where space constraints favor a 2MHz frequency to reduce inductor size. Consider the 350mA maximum output current when sizing the LED load. Verify that the SOIC-8 package fits the PCB layout constraints.

LED Driver IC Part Context

This part belongs to the MAX16822 family of high-brightness LED drivers. It shares functional similarities with other members like the MAX16822B but may differ in specific electrical characteristics or automotive qualification levels. The series is targeted at cost-effective illumination solutions replacing discrete transistor designs.

LED Driver IC Replacement Considerations

Direct substitutes include the MAX16822BASA+T within the same family. Verify if the 'B' variant meets all automotive and electrical requirements before substitution.
