The LP5860T 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 . The LP5860T integrates 11 MOSFETs for up to 198 LED dots or 66 RGB LEDs.

The LP5860T 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-noise-free dimming control. Each LED dot can also be arbitrarily mapped into 8-bit Group PWM to achieve dimming control together.

The LP5860T device implements full addressable SRAM to minimize the data traffic. The ghost-cancellation circuitry is integrated to eliminate both upside and downside ghosting. The LP5860T also supports LED open and short detection functions. Both 1MHz (maximum) I2C and 12MHz (maximum) SPI are available in LP5860T.
