Product Description
LP5860RKPR LED Driver IC 18 Output Linear Constant Current Analog 50mA 40-VQFN (5x5)
Features of LP5860RKPR
LED matrix topology:
– 18 constant current sinks with 11 scan switches
for 198 LED dots
– Configurable for 1 to 11 scan switches
• Operating voltage range:
– VCC/VLED range: 2.7 V to 5.5 V
– Logic pins compatible with 1.8 V, 3.3 V, and 5 V
• 18 constant current sinks with high precision:
– 0.1mA–50 mA per current sink when VCC ≥ 3.3
V
– Device-to-device error: ±3% when channel
current = 50 mA
– Channel-to-channel error: ±3% when channel
current = 50 mA
– Phase-shift for balanced transient power
• Ultra-low power consumption:
– Shutdown mode: ICC ≤ 1 uA when EN = Low
– Standby mode: ICC ≤ 10 uA when EN = High
and CHIP_EN = 0 (data retained)
– Active mode: ICC = 4.3 mA (typ.) when channel
current = 5 mA

Overview of LP5860RKPR
The LP5860 is an 11 × 18 LED matrix driver. The device integrates 11 switching FETs with 18 constant current
sinks. One LP5860 device can drive up to 198 LED dots or 66 RGB pixels by using time-multiplexing matrix
scheme.
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. The device 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 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 LP5860.
