ST2226B PWM-Controlled Constant Current Driver

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 m.

ST2226B Features

* ˙ Constant current outputs with current value settings by an external resistor ˙ Maximum output current: 60 mA ˙ Time division output allows the driving of 1 or 2 LEDs with a single output ˙ Maximum / minimum output voltage: 17V / 1.25V ˙ 10 bits luminance data with PWM current outputs ˙ Serial shif
