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-compatible serial interface.
The open LED detection function indicates a broken or disconnected LED at one or more of the outputs.
The overtemperature flag ind...
