The LP5862 is an 2 × 18 LED matrix driver. The device integrates 2 switching FETs with 18 constant current sinks. One LP5862 device can drive up to 36 LED dots or 12 RGB pixels by using time-multiplexing matrix scheme.

The LP5862 supports both analog dimming and PWM dimming methods. For analog dimming, the current gain of each individual LED dot can be adjusted with 256 steps through 8-bits dot correction. For PWM dimming, the integrated 8-bits or 16-bits configurable, > 20-KHz PWM generators for each LED dot enable smooth, vivid animation effects without audible noise. Each LED can also be mapped into a 8-bits group PWM to achieve the group control with minimum data traffic.

The LP5862 device implements full addressable SRAM. The device supports entire SRAM data refresh and partial SRAM data update on demand to minimize the data traffic. The LP5862 implements the ghost cancellation circuit to eliminate both upside and downside ghosting. The LP5862 also uses low brightness compensation technology to support high density LED pixels. Both 1-MHz (maximum) I²C and 12-MHz (maximum) SPI interfaces are available in the LP5862.
