CXA2108Q Overview
The CXA2108Q is a 1,024-gradation LED driver which is ideal for full color LED displays. This IC has 24 outputs and a maximum output current of 60mA. Time division allows driving of either two or six LEDs per output by connecting an external FET or other switch.
CXA2108Q Key Features
- 24 outputs: 10-bit (1,024-gradation) PWM current outputs
- Maximum output current: 60mA
- LED type: mon anode
- 4-bit brightness function capable of switching the basic PWM pulse width in 16 steps
- Time division allows driving of up to six LEDs with a single output, making it possible to configure a high definition d
- Coarse Adj. (2 bits) and Fine Adj. (8 bits) output current adjustment for each LED makes it possible to drive R, G and B
- All luminance (PWM) data and drive current data are set by writing to the internal RAM
- PWM emitting can be performed up to 15 times per frame to realize a screen with little flicker
- Two built-in PWM data RAM make it possible to set the next luminance data even during PWM operation
- Abnormal internal temperature detection circuit
