PWM grayscale control
This IC is possible to PWM grayscale control by the input of the PWM signal to the EN terminal.
When PWM grayscale control is done, we recommend the LED power-supply voltage to be set to become the
satiety region of the constant current characteristic. When using this IC outside the saturation area, PWM grayscale
control cannot be normally done.
Switching to Open Circuit Detection (OOD) and Short Circuit Detection (OSD) Modes
Switching to OSD mode
SCK

OE H L H H H H
SLAT L L L H L L
The signal sequence set to be in the OSD mode. Here, the SLAT active pulse would not latch any data.
Switching to OOD mode
SCK

OE H L H H H H
SLAT L L L L L H
The signal sequence set to be in the OOD mode. Here, the SLAT active pulse would not latch any data.
