1.1 Overview
The LP5810 is a 4-Channel RGBW LED driver with autonomous animation engine control. The LP5810 has ultra-low operation current at active mode, consuming 0.4 mA when LED maximum current setting is 25.5 mA. If all LEDs are turned off, the device enters standby state to reduce power consumption with data retained. When 'chip_enable' bit setting is 0, initial state is entered with minimum power consumption to save power.
The LP5810 supports both analog dimming and PWM dimming. In analog dimming, the output current of each LED can be adjusted with 256 steps. In PWM dimming, the integrated 8-bit configurable PWM generator enables smooth brightness dimming control. Optional exponential PWM dimming can be activated for individual LED to achieve a human-eye-friendly visual performance.
The LP5810 integrates autonomous animation engine, with no need for brightness control commands from controller. Each LED has an individual animation engine which can be configured through the related registers. The device can generate a 6 MHz clock signal, which synchronizes the lighting effects among multiple devices.
The LP5810 has 4 different material versions with different I2C chip address. Up to 4 LP581x devices can be connected to the same I2C bus and controlled individually.
