3 Description

The LP5861T is a high-current and high-performance

LED matrix driver. The device integrates 18 constant

current sinks with N (N = 6/8/11) switching MOSFETs

to support N × 18 LED dots or N × 6 RGB LEDs. The

LP5861T is the direct driving version to support 18

LED dots or 6 RGB LEDs.

The LP5861T supports both analog dimming and

PWM dimming methods. For analog dimming, each

LED dot can be adjusted with 256 steps. For PWM

dimming, the integrated 8-bit or 16-bit configurable

PWM generators enable smooth and audible-noisefree

dimming control. Each LED dot can also be

arbitrarily mapped into 8-bit Group PWM to achieve

dimming control together.

The LP5861T device implements full addressable

SRAM to minimize the data traffic. The ghostcancellation

circuitry is integrated to eliminate both

upside and downside ghosting. The LP5861T also

supports LED open and short detection functions.

Both 1-MHz (maximum) I2C and 12-MHz (maximum)

SPI are available in LP5861T.
