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.
