LP5861 18-Channel LED Driver With 8-Bit Analog and 8-/16-Bit PWM Dimming
1 Features
- 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:
- 0.1 mA–50 mA per current sink when VCC
≥ 3.3 V
- Device-to-device error: ±5%
- Channel-to-channel error: ±5%
- Phase-shift for balanced transient
power
- Ultra-low power consumption:
- Shutdown mode: ICC ≤ 2 uA
when EN = Low
- Standby mode: ICC ≤ 10 uA
when EN = High and CHIP_EN = 0 (data retained)
- Active mode: ICC = 3 mA (typ.) when
channel current = 5 mA
- Flexible dimming options:
- Individual ON and OFF control for each LED
dot
- Analog dimming (current gain
control)
- Global 3-bit Maximum Current (MC)
setting for all LED dots
- 3 groups of 7-bit Color Current
(CC) setting for red, green, and blue
- Individual 8-bit Dot Current (DC)
setting for each LED dot
- PWM dimming with audible-noise-free
frequency
- Global 8-bit PWM dimming for all
LED dots
- 3 programmable groups of 8-bit
PWM dimming for LED dot arbitrary mapping
- Individual 8-bit or 16-bit PWM
dimming for each LED dot
- Full addressable SRAM to minimize data
traffic
- Individual LED dot open and short detection
- Deghosting and low brightness
compensation
- Interface options:
- 1-MHz (max.) I2C interface
when IFS = Low
- 12-MHz (max.) SPI interface when IFS
= High
