Краткое описание:
4 × 18 LED matrix driver with 8-bit analog and 8-/16-bit PWM dimming
Дополнительная информация
The LP5864 is a high-performance LED matrix driver capable of driving 72 LED dots using 4 scan switches and 18 constant current sinks. It features a high-precision current sink range of 0.1 mA to 50 mA per channel with ±5% accuracy. The device supports flexible dimming including individual 8-bit or 16-bit PWM dimming and 8-bit analog dot current setting. It includes features for ghosting cancellation, LED open/short detection, and ultra-low power modes with a shutdown current of 2 µA.
