12-Channel LED Driver with Dot Correction and Greyscale PWM
1 General Description
The AS1122 is a 12-channel, constant current-sink LED driver. Each of the 12 channels can be individually adjusted by 4096-step greyscale PWM brightness control and 64-step constant-current sink (dot correction).
The dot correction circuitry adjusts the brightness variations between the AS1122 channels and other LED drivers. Greyscale control and dot correction circuitry are accessible via a simple SPI-patible serial interface.
The open LED detection function indicates a broken or disconnected LED at one or more of the outputs. The overtemperature flag...
