ADP8870 Product details

Description

The ADP8870 combines a programmable backlight LED charge-pump driver with automatic phototransistor control of the brightness (LED current) and a PWM input to control the scale of the output current.

Features

Charge pump with automatic gain selection of 1×, 1.5×, and 2× for maximum efficiency Two high accuracy (±5%) phototransistor inputs for automated ambient light sensing (ALS) 5 programmable ambient light-sensing zones for optimal backlight power savings Independent ALS control of D7, for automated response of keypad lighting to ambient light levels PWM input can be used for content adaptive brightness control (CABC) of any, or all, of the LEDs PWM input scales the LED output current 7 independent.
