MAX6969ANG+

LED Driver IC Overview

The MAX6969ANG+ is a 16-port LED display driver manufactured by Analog Devices Inc./Maxim Integrated. It features constant-current drive capability with an output voltage of 5.5V and a channel current of 55mA. The device operates within a supply voltage range of 3V to 5.5V and supports a wide operating temperature range from -40°C to +125°C. It utilizes a shift register topology for data handling and is housed in a 24-pin SOIC package designed for through-hole mounting.

LED Driver IC Feature Summary

• Provides linear constant-current drive for multiple LED segments
• Integrates internal shift register for serial data input
• Supports high-temperature operation suitable for industrial environments

LED Driver IC Applications

• Signage displays
• Multi-segment LED indicators
• Industrial control panel interfaces

LED Driver IC Procurement Notes

Verify the specific suffix 'ANG+' indicates through-hole packaging, as other variants like 'AWG' use surface-mount packages. Confirm availability status directly with authorized distributors, as lead times may vary. Ensure the design accommodates the 24-pin SOIC footprint and thermal requirements for continuous operation at maximum ambient temperatures.

LED Driver IC Selection Notes

Select this component when through-hole assembly is required for robust mechanical stability in signage or industrial applications. Compare against surface-mount variants if board space is limited. Ensure the host microcontroller can provide the necessary clock and data signals for the shift register interface. Verify that the 55mA per-channel current rating matches the LED specifications without exceeding power dissipation limits.

LED Driver IC Part Context

This part belongs to the MAX6969 family of LED drivers, which are designed for driving complex LED displays. The family includes various package options such as TQFN and SOIC to suit different manufacturing needs. These drivers typically integrate current regulation and dimming capabilities to simplify system design for multi-segment displays.

LED Driver IC Replacement Considerations

The MAX6969AWG+ serves as a functional equivalent but utilizes a surface-mount SOIC package instead of through-hole. Designers must evaluate PCB layout changes and assembly process adjustments when substituting between these package types.
