LP8865ZQDMTRQ1

LED Driver IC Overview

The LP8865ZQDMTRQ1 is an automotive-grade, single-channel LED lighting driver IC from the Texas Instruments LP8865Z series. It utilizes a buck topology to deliver up to 2 A of output current with a maximum supply voltage of 65 V and a minimum of 4.5 V. The device operates at a programmable switching frequency ranging from 100 kHz to 2.2 MHz and supports analog, PWM, flexible, and hybrid dimming methods. Housed in a VSON-14 package, it functions within a temperature range of -40°C to +125°C.

LED Driver IC Procurement Notes

Verify the complete part number against official Texas Instruments documentation to ensure correct suffix alignment. Confirm that the specific ordering code matches the required package type and temperature rating. Cross-reference datasheet revisions to validate feature availability. Ensure compliance with automotive quality standards specified in the manufacturer's release notes before finalizing procurement specifications.

LED Driver IC Selection Notes

Select this component when a single-channel buck driver with integrated switching FET is required for automotive environments. Consider the 65-V input capability and 2-A output capacity for driving high-power LEDs. Evaluate the need for hybrid or flexible dimming support versus standard PWM control. Verify that the VSON-14 package fits the available PCB real estate and thermal management requirements.

LED Driver IC Part Context

This device belongs to the LP8865 family of automotive LED drivers designed for robust performance in vehicle lighting architectures. It shares the VSON-14 form factor with other variants in the series but differs in topology and control features. The 'Z' suffix typically denotes specific configuration options within the product line, distinguishing it from boost or multi-topology counterparts.
