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
- 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/short detection
- De-ghosting and low brightness compensation
- Interface options:
- 1-MHz (max.) I2C interface when IFS = Low
- 12-MHz (max.) SPI interface when IFS = High
Electronic devices are becoming smarter, requiring to use larger quantity of LEDs for animation and indication purposes and high performance LED matrix driver is required to improve user experience with small solution size.
The LP586x devices are a family of high performance LED matrix drivers. The devices integrate 18 constant current sinks with N (N = 1/2/4/6/8/11) switching MOSFETs to support N × 18 LED dots or N × 6 RGB LEDs. The LP5860 integrates 11 MOSFETs for up to 198 LED dots or 66 RGB LEDs.
The LP5860 supports both analog dimming and PWM dimming methods. For analog dimming, each LED dot can be adjusted with 256 steps. For PWM dimming, the integrated 8-bit or 16-bit configurable PWM generators enable smooth and audible-noise-free dimming control. Each LED dot can also be arbitrarily mapped into 8-bit Group PWM to achieve dimming control together.
The LP5860 device implements full addressable SRAM to minimize the data traffic. The ghost-cancellation circuitry is integrated to eliminate both upside and downside ghosting. The LP5860 also supports LED open and short detection functions. Both 1-MHz (maximum) I2C and 12-MHz (maximum) SPI are available in LP5860.
