Programmable Current Backlight Driver with Ambient Light Sensor Input
The ADP5501 can detect ambient light levels and adjust the backlight brightness accordingly, resulting in extended battery life. Once configured, the ADP5501 is capable of controlling the display backlight intensity, on/off timing, dimming, and fading without the intervention of the main processor, which translates into valuable battery power savings. The three auxiliary LEDs are also capable of fading and are timed on and off via register programming.
