MAX6946ATE+

LED Driver IC Overview

The MAX6946ATE+ is a 10-port constant-current LED driver IC manufactured by Analog Devices Inc. It operates within an input voltage range of 2.25 V to 3.6 V and delivers a low-level output current of 21.12 mA per channel. The device supports PWM dimming and utilizes a TQFN-16 package for surface mount installation. It functions as a boost topology driver with a maximum power dissipation of 1.176 W and a maximum supply current of 60 uA. The component is rated for operation between -40°C and +125°C.

LED Driver IC Feature Summary

• Provides ten independent constant-current output channels for uniform LED illumination
• Supports pulse-width modulation (PWM) dimming control for brightness adjustment
• Integrates boost topology to drive LED loads from low-voltage sources

LED Driver IC Applications

• Portable electronic display backlighting systems
• LED indicator arrays in consumer devices
• Compact lighting modules requiring multi-channel current regulation

LED Driver IC Procurement Notes

Verify the specific suffix 'ATE+' against official Analog Devices documentation to confirm pinout, temperature grade, and RoHS compliance status. Ensure the TQFN-16 package dimensions match your PCB footprint requirements. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

LED Driver IC Selection Notes

Select this component when designing circuits requiring ten synchronized constant-current outputs from a single low-voltage supply. The wide operating temperature range makes it suitable for industrial or automotive environments where thermal stability is critical. Consider the 21.12 mA output capability to ensure compatibility with the target LED forward voltage and current specifications.

LED Driver IC Part Context

This device belongs to the MAX6947 family of LED drivers, sharing similar functional architectures but differing in port counts and specific electrical characteristics. It serves as a specialized solution for applications needing multiple regulated current sources without external sensing resistors on each channel, simplifying the overall bill of materials.
