Description
Serial Data Shift Clock
Serial Data Input
Mode Select input with internal pulldown
MODE = GND: Selects greyscale mode (see Setting Greyscale Brightness on page 14)
MODE = V CC : Selects dor correction mode (see Setting Dot Correction on page 13)
Constant-Current Outputs 0:7
Constant-Current Outputs 8:15
Error Output
0 = LED open detection or overtemperature condition is detected.
1 = Normal operation.
Serial Data Output
Greyscale Clock. Reference clock for greyscale PWM control
Reference Current Terminal
Power Supply Voltage
This pins must not be connected
Power Down
0 = normal operation mode
1 = power down mode
Ground
Blank Outputs
0 = OUT n outputs are controlled by the greyscale PWM control.
1 = OUT n outputs are forced off; the greyscale counter is reset.
Data Latch. The internal connections are switched by pin MODE.
For LD (MODE = GND), the greyscale register receives new data.
For LD (MODE = V CC ), the dot correction register receives new data.
Thermal Pad. This pin must be connected to GND to ensure normal operation.
