Description

General part information

LP5861T Series

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-noise-free 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 ghost-cancellation circuitry is integrated to eliminate both upside and downside ghosting. The LP5861T also supports LED open and short detection functions. Both 1-MHz (maximum) I 2C and 12-MHz (maximum) SPI are available in LP5861T.
