MAX6969AUG+

LED Driver IC Overview

The MAX6969AUG+ is a 16-port LED display driver manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 3V to 5.5V and provides a maximum output voltage of 5.5V per channel. Each channel delivers a constant current of 55mA, with a low-level output current capability of 60mA. The device features a linear topology with internal switches and utilizes a shift register interface for control. It is housed in a 24-TSSOP package (0.295" width) and supports surface mount installation. The component functions within an operating temperature range of -40°C to +125°C TA.

LED Driver IC Feature Summary

• Provides 16 independent constant-current LED drive channels
• Integrates linear shift register architecture for serial data input
• Supports high-temperature operation up to 125°C ambient
• Includes internal switching mechanisms for direct LED connection

LED Driver IC Applications

• Signage displays
• General LED indicator arrays
• Consumer electronic status panels

LED Driver IC Procurement Notes

Verify the specific suffix 'AUG+' against the official datasheet to confirm the TSSOP-24 package and lead-free compliance status. Ensure the design accommodates the 55mA per-channel current limit and the 3V to 5.5V supply range. Confirm thermal management requirements for the 24-pin surface-mount package under maximum load conditions at elevated ambient temperatures.

LED Driver IC Selection Notes

Select this component when a 16-channel solution is required for static or multiplexed LED displays. It is suitable for designs needing integrated shift register functionality without external logic. Consider the 55mA output current as sufficient for standard indicator LEDs but potentially insufficient for high-power applications requiring higher brightness levels without additional circuitry.

LED Driver IC Part Context

This part belongs to the MAX6968/MAX6969 family of LED display drivers from Maxim Integrated. While the MAX6968 offers 8 ports, the MAX6969 doubles this capacity to 16 ports, maintaining similar control interfaces and electrical characteristics. Both devices serve as compact solutions for managing multiple LED segments in space-constrained embedded systems.
