Краткое описание:
16-Channel, 12-Bit PWM LED Driver with 6-Bit Dot Correction
Дополнительная информация
The TLC5946 is a 16-channel, constant current sink LED driver. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps and 64 constant current sink steps for dot correction. The dot correction adjusts the brightness variations between LEDs. Both grayscale control and dot correction are accessible via a serial interface. The maximum current value of all 16 channels can be set by a single external resistor. It includes LED open detection (LOD) and a thermal error flag (TEF).
