MAX6968AUE+T

LED Driver IC Overview

The MAX6968AUE+T is an 8-port constant-current LED display driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3 V to 5.5 V and delivers a low-level output current of 60 mA per channel. The device features a maximum power dissipation of 1.702 W and functions across an operating temperature range of -40°C to +85°C. It utilizes a 16-segment architecture housed in a TSSOP-16 surface-mount package.

LED Driver IC Feature Summary

• Provides eight independent constant-current output ports for direct LED driving
• Integrates a serial shift register interface for simplified data input
• Supports linear dimming control for brightness adjustment

LED Driver IC Applications

• Signage displays
• General lighting systems
• LED indicator arrays

LED Driver IC Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the '+T' designation aligns with lead-free manufacturing standards required by your assembly process. Ensure compatibility with the 16-TSSOP exposed pad footprint during PCB layout verification.

LED Driver IC Selection Notes

Select this component when an 8-channel constant-current solution is required for segment-based LED displays. The TSSOP-16 package suits space-constrained designs needing surface-mount integration. Verify that the 60 mA sink capability meets the forward current requirements of the target LEDs without external transistors.

LED Driver IC Part Context

This part belongs to the MAX6968 series of LED drivers designed for high-density display applications. It serves as a bridge between microcontroller serial interfaces and LED matrices, simplifying wiring complexity compared to parallel drive schemes.

LED Driver IC Replacement Considerations

Check for pin-compatible alternatives within the same family if supply constraints exist. Verify that substitute parts maintain identical 8-port architectures and similar current sinking capabilities to ensure functional parity.
