ST2226B Description
The ST2226B is a LED driver incorporating shift registers, data latches, 16-channel constant current circuitry with current value set by an external resistor, 1024 gray level PWM (Pulse Width Modulation) functional unit and time division capability. Each channel can provide a maximum current of 60 mA. Time division operation allows driving up to 1 or 2 LEDs with a single output channel (mode-1 and mode-2...
