The LP5867 is a 7 × 6 LED matrix driver. The device integrates 7 switching FETs with 6 constant current sinks. One LP5867 device can drive up to 42 LED dots or 14 RGB pixels by using time-multiplexing matrix scheme.

For analog dimming, the current gain of each individual LED dot is adjustable with 256 steps through 8-bits dot correction. For PWM dimming, the integrated 8-bits, or 16-bits, PWM generators generate more than 20KHz PWM for each LED dot which enables smooth, vivid animation effects without audible noise. Each LED can be mapped into an 8-bits group PWM to achieve group control with minimum data traffic.

The LP5867 device implements fully addressable SRAM. The device supports an on demand entire SRAM data refresh and a partial SRAM data update to minimize data traffic. The LP5867 implements the ghost cancellation circuit to eliminate both upside and downside ghosting. The LP5867 uses low-brightness compensation technology to support high-density LED pixels.
