SNVSCE4A may 2023 – august 2023 LP5861T
PRODUCTION DATA
The LP5861T is an 18 channels high power LED driver. The device integrates 18 high-precision constant-current sinks. One LP5861T device can drive up to 18 LED dots or 6 RGB pixels by directly driving the LEDs.
The LP5861T 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 LP5861T 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 LP5861T implements the ghost cancellation circuit to eliminate both upside and downside ghosting. The LP5861T 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 LP5861T.
