LP8865XQDMTRQ1

LED Driver IC Overview

The LP8865XQDMTRQ1 is an automotive-grade, multi-topology LED driver IC from Texas Instruments. It integrates a high-side power FET capable of delivering up to 2.5 A output current. The device supports Buck and Boost topologies with an input voltage range of 4.5 V to 63 V. It features programmable switching frequencies between 100 kHz and 2.2 MHz. Key functional attributes include inductive fast dimming, hybrid PWM/analog dimming capabilities, and integrated protection mechanisms such as thermal shutdown and over-current protection. The component is housed in a 14-pin VSON package.

LED Driver IC Feature Summary

• Supports both Buck and Boost converter topologies for flexible LED string configurations
• Integrates a high-side power FET with inductive fast dimming capability
• Provides hybrid dimming control combining analog and PWM methods

LED Driver IC Applications

• Automotive exterior lighting systems
• LED headlamp modules
• Adaptive driving beam applications

LED Driver IC Procurement Notes

Verify the specific suffix 'X' against the official Texas Instruments datasheet to confirm pinout and feature set compatibility. Ensure the Q1 designation aligns with automotive reliability standards required for your application. Cross-reference the VSON-14 package dimensions with your PCB layout constraints before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a single-channel driver supporting both step-down and step-up operations is required. The integrated high-side switch simplifies design by reducing external component count. Consider the inductive fast dimming feature if precise low-frequency flicker-free performance is necessary for automotive compliance.

LED Driver IC Part Context

This part belongs to the LP8865-Q1 family of multi-topology LED drivers. It shares core architecture with variants like LP8865Z and LP8865V but differs in specific marking and potentially internal configuration. The 'X' suffix distinguishes it within the broader LP8865 series product line.

LED Driver IC Replacement Considerations

LP8865ZQDMTRQ1 and LP8865VQDMTRQ1 are related members of the same family. Verify electrical parameter equivalence and pin compatibility before substitution.
