LP8867CQPWPRQ1

LED Driver IC Overview

The LP8867CQPWPRQ1 is a highly integrated automotive LED lighting driver IC featuring four output channels with a maximum current of 120 mA per channel. It supports Boost and SEPIC topologies, operating within an input voltage range of 4.5 V to 40 V and delivering an output voltage between 6 V and 45 V. The device operates at a switching frequency from 300 kHz to 2.2 MHz and includes overvoltage protection. Packaged in a 20-lead HTSSOP, it is qualified to AEC-Q100 standards for operation between -40°C and +125°C.

LED Driver IC Feature Summary

• Integrates four high-side constant-current sinks with adjustable output current up to 120 mA.
• Supports both Boost and SEPIC converter topologies for flexible LED string configurations.
• Includes built-in overvoltage protection to safeguard the system against transient voltage spikes.

LED Driver IC Applications

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

LED Driver IC Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-20 package and Reel tape-and-reel packaging configuration. Confirm AEC-Q100 qualification status aligns with project requirements. Check for moisture sensitivity level (MSL) ratings to ensure proper storage and handling procedures are followed during assembly. Validate that the 4.5 V minimum input voltage meets the vehicle's electrical architecture specifications.

LED Driver IC Selection Notes

Select this component when a compact solution for multi-channel automotive LED control is required. The integrated Boost/SEPIC controller reduces external component count compared to discrete solutions. Ensure the application demands a switching frequency above 300 kHz to minimize passive component size while avoiding AM radio interference bands. Verify that the 120 mA per channel limit satisfies the target LED forward current requirements.

LED Driver IC Part Context

This part belongs to the Texas Instruments LP8867 family of automotive LED drivers. It is designed specifically for high-reliability automotive environments, offering integration of power switches and control logic. The device complements other members of the LP886x series by providing a balanced solution for mid-density LED arrays in exterior lighting applications.

LED Driver IC Replacement Considerations

LP8867CQPWPR: Non-automotive grade version with identical electrical characteristics but without AEC-Q100 certification. LP8867QPWPRQ1: Alternative variant within the same family; verify pinout and feature set compatibility before substitution.
