MAX6970AUE+T

LED Driver IC Overview

The MAX6970AUE+T is an 8-port, constant-current LED driver IC manufactured by Analog Devices Inc./Maxim Integrated. It utilizes a linear topology with shift register control to manage up to eight independent LED channels. The device supports a supply voltage range of 3V to 5.5V and can drive outputs up to 36V. Each channel provides a fixed output current of 55mA. It operates within a temperature range of -40°C to +125°C and is housed in a 16-TSSOP-EP package.

LED Driver IC Feature Summary

• Provides eight independent constant-current output channels for precise LED intensity control
• Integrates a serial shift register interface for simplified microcontroller connectivity
• Supports high-voltage LED loads with individual channel regulation capabilities

LED Driver IC Applications

• General LED lighting systems requiring multi-channel control
• Signage applications utilizing high-voltage LED arrays
• Industrial display modules needing robust thermal operation

LED Driver IC Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 16-TSSOP-EP footprint matches your PCB layout constraints. Cross-reference the exact part number with authorized distributors to avoid counterfeit components.

LED Driver IC Selection Notes

Select this component when designing circuits that require multiple independently controlled LED channels with high voltage tolerance. The linear topology suits applications where power dissipation is manageable and cost efficiency is prioritized over switching regulator complexity. Verify that the 55mA per channel current rating meets the specific LED requirements of the target application.

LED Driver IC Part Context

This part belongs to the MAX6970 family of LED drivers from Maxim Integrated, now part of Analog Devices. The series focuses on providing reliable, high-voltage constant-current solutions for industrial and commercial lighting. The AUE variant specifically denotes the automotive-grade or extended temperature performance within the standard TSSOP-EP form factor.

LED Driver IC Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6970 series, such as the MAX6970AWE+, which may offer different package options. Evaluate other 8-channel LED drivers from Analog Devices if higher efficiency or different control interfaces are required.
