MAX8901AETA+T

LED Driver IC Overview

The MAX8901AETA+T is a high-efficiency LED lighting driver IC designed for driving two to six series-connected white LEDs (WLEDs). It operates within an input voltage range of 2.6 V to 5.5 V and delivers a constant current output to ensure uniform WLED intensity. The device is housed in a compact 2mm x 2mm TDFN package with an exposed pad, suitable for space-constrained designs. It features a maximum power dissipation of 953 mW and operates across a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Provides constant current drive for uniform white LED intensity
• Supports configurations of two to six series-connected WLEDs
• Integrated boost converter topology for efficient step-up operation

LED Driver IC Applications

• LCD backlighting systems
• Space-constrained wearable electronics
• Mobile handheld devices requiring high-efficiency illumination

LED Driver IC Procurement Notes

Verify the specific suffix 'ETA' against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Confirm availability status as distribution channels may list obsolete or limited-stock variants. Ensure the ordering part number matches the exact package type required for your PCB layout constraints.

LED Driver IC Selection Notes

Select this component when designing circuits that require driving multiple series white LEDs from a single-cell lithium battery source. The 2.6 V minimum input voltage allows operation until significant battery depletion. Consider the 2mm x 2mm footprint if board real estate is critical compared to larger QFN packages.

LED Driver IC Part Context

This part belongs to the MAX8901B family of LED drivers from Analog Devices/Maxim Integrated. It serves as a specialized power management solution for portable electronics, distinct from general-purpose switching regulators. The family focuses on optimizing efficiency for display backlighting applications where size and battery life are primary design constraints.

LED Driver IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative drivers by matching electrical specifications such as input voltage range, output current capability, and package dimensions.
