The LP5866T is a high-performance LED matrix driver integrating 18 constant current sinks with 6 scan switches to support up to 108 LED dots or 36 RGB LEDs. It features 8-bit analog dimming and configurable 8-bit or 16-bit PWM dimming. The device includes ghost-cancellation circuitry, low brightness compensation, and full addressable SRAM to minimize data traffic. It is designed for applications requiring high-density LED animation and indication with ultra-low power consumption in shutdown and standby modes.
