LED Driver IC datasheet and documents for MIC3289-16YD6-TR

MIC3289-16YD6-TR

LED Driver IC Overview

The MIC3289-16YD6-TR is a PWM boost-switching regulator optimized for constant-current white LED driver applications. It features an internal Schottky diode and supports up to 4 WLEDs with a 16V overvoltage protection option. The device operates within an input voltage range of 2.5V to 6.5V and switches at a frequency of 1.2MHz. It provides a maximum switch current of 1.2A and includes true 1-Wire digital control for brightness adjustment. The component is housed in a TSOT-23-6 package and functions reliably across an operating temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

Integrates a 1-Wire interface for digital brightness control and shutdown management
Includes an internal Schottky diode to minimize external component count
Provides 16-level logarithmic brightness adjustment capabilities

LED Driver IC Applications

White LED backlighting systems
Portable electronic device illumination
Constant-current LED driver circuits

LED Driver IC Procurement Notes

Verify the specific suffix '16' indicates the 16V overvoltage protection variant, as other variants may offer different protection levels. Confirm the '-TR' designation corresponds to the tape and reel packaging format required for automated assembly processes. Ensure compatibility with the 1-Wire protocol implementation in the host system design.

LED Driver IC Selection Notes

Select this component when a compact solution for driving multiple white LEDs is required. The integrated Schottky diode reduces board space compared to designs using external rectifiers. The 1-Wire interface allows for simplified control lines compared to traditional PWM dimming methods. Consider the 1.2A switch current limit when sizing the external inductor for the target load.

LED Driver IC Part Context

This part belongs to the MIC3289 family of LED drivers from Microchip Technology. The family shares common architecture but varies by overvoltage protection ratings and output configurations. The MIC3289 specifically targets single-channel boost applications for white LEDs, distinguishing it from multi-channel or buck-boost variants in the broader portfolio.
