SNVU786 May 2021 LP5860
The LP5860 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 LP5860 device implements full addressable SRAM. It supports entire SRAM data refresh and partial SRAM data update on demand to minimize the data traffic. The LP5860 implements the ghost cancellation circuit to eliminate both upside and downside ghosting. The LP5860 also utilizes low brightness compensation technology to support high density LED pixels. Both 1-MHz (max.) I2C and 12-MHz (max.) SPI interfaces are available in the LP5860.
