LP5860TMRKPR

LED Driver IC Overview

The LP5860TMRKPR is a high-current LED matrix driver from Texas Instruments, featuring an 11 x 18 output configuration. It integrates 18 constant current sinks with N switching MOSFETs (where N=11). The device operates on a supply voltage of 2.7 V to 5.5 V and supports PWM dimming. It is housed in a VQFN-40 package and functions within a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Integrates 18 constant current sinks with 11 switching MOSFETs for high-current matrix driving
• Supports flexible analog and PWM mixed dimming control
• Includes built-in protection features such as thermal shutdown and LED open/short detection

LED Driver IC Applications

• High-brightness LED matrix displays
• LED backlighting systems requiring high current
• Industrial LED indication panels

LED Driver IC Procurement Notes

Verify the specific suffix 'MRKPR' against the manufacturer's datasheet to confirm the extended industrial temperature range (-40°C to +125°C) and reel packaging specifications. Ensure compatibility with I2C/SPI control interfaces if digital dimming is required. Cross-reference the VQFN-40 footprint with your PCB layout guidelines.

LED Driver IC Selection Notes

Select this component when an 11x18 matrix topology is required with high individual channel current capabilities. It is suitable for applications needing integrated switching MOSFETs to reduce external component count. Compare with the LP5860TRKPR if a lower temperature range is acceptable, or the LP5868TMRKPR if lower current per channel suffices.

LED Driver IC Part Context

This part belongs to the LP5860T series of high-performance LED matrix drivers. It is designed to simplify the design of complex LED arrays by integrating both the sink drivers and the necessary switching elements. The series offers scalable solutions for various matrix sizes depending on the number of integrated MOSFETs.

LED Driver IC Replacement Considerations

The LP5860TRKPR is a related variant with a different operating temperature range. Verify pinout and electrical characteristics before substitution.
