Tiger Power ADP-5501 Programmable Current Backlight Driver with Ambient Light Sensor Input Simple Type: TBD
The ADP5501 is a versatile, single-chip, white LED back-light driver with programmable ambient light sensor input and programmable LED current. This device is designed for media-enabled handset applications. The ADP5501 uses an I2C-compatible serial interface and a single line interrupt to communicate with the host processor. The ADP5501 can detect ambient light levels and adjust the back-light brightness accordingly, resulting in extended battery life. Once configured, the ADP5501 is capable of controlling the display back-light 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.
