MAX6969AUG+T

LED Driver IC Overview

The MAX6969AUG+T is a 16-port LED display driver manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input supply voltage range of 3V to 5.5V and provides constant-current drive capability up to 5.5V output. Each channel delivers a maximum output current of 55mA, supporting high-efficiency LED control. The device features a shift register topology for data handling and includes internal switches for direct LED connection. It is housed in a 24-TSSOP package (0.295" width) designed for surface-mount installation. The component supports a wide operating temperature range from -40°C to +125°C, ensuring reliability in demanding environments.

LED Driver IC Feature Summary

• Provides 16 independent constant-current channels for uniform LED brightness control
• Integrates a shift register interface for simplified serial data communication
• Includes internal power switches to reduce external component count
• Supports linear dimming functionality for precise intensity adjustment

LED Driver IC Applications

• LED signage displays
• Dot matrix graphic displays
• Numeric seven-segment displays

LED Driver IC Procurement Notes

Verify the exact suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'A' grade designation matches required performance specifications. Ensure the TSSOP-24 footprint aligns with PCB layout constraints. Cross-reference the manufacturer part number MAX6969AUG+T against official Analog Devices documentation to validate authenticity and revision status before procurement.

LED Driver IC Selection Notes

Select this component when a high-channel-count LED driver with integrated current regulation is required. The 55mA per channel rating suits standard indicator and segment LEDs. Consider the 24-pin TSSOP package size for space-constrained designs. Verify that the 3V to 5.5V supply range matches the system power architecture. Evaluate thermal dissipation requirements given the 975mW power dissipation capability in the specified package.

LED Driver IC Part Context

This part belongs to the Maxim Integrated LED driver family, specifically designed for multiplexed display applications. It replaces older discrete driver solutions by integrating multiple channels into a single IC. The MAX6969 series offers a balance of performance and pin count, suitable for medium-density displays. Analog Devices continues to support this line through its Maxim Integrated product portfolio.

LED Driver IC Replacement Considerations

Check for MAX6969AWG+T as a potential alternative with different packaging options. Verify compatibility with existing firmware if using shift register interfaces. Ensure substitute parts maintain the same 55mA current rating and 16-channel configuration.
