ADP8863
Overview
The ADP8863 combines a powerful charge pump driver with advanced autonomous LED lighting features. It allows as many as seven LEDs to be independently driven up to 30 mA (maximum).
- 1 sec to 5.5 sec Selectable linear, square, or cubic fade rates 7 independent and programmable LED drivers 7 drivers capable of 30 mA (maximum) 1 driver also capable of 60 mA (maximum) Programmable maximum current limit (128 levels) Separate and independent controls for backlight LEDs Backlight fade override Up to two built-in comparator inputs with programmable modes for ambient light sensing Charge pump with automatic gain selection of 1×, 1.5×, and 2× for maximum efficiency Standby mode for <1 μA current consumption I2C-compatible interface for all programming Dedicated reset pin and built-in power-on reset (POR) Short-circuit, overvoltage, and overtemperature protection Internal soft start to limit inrush currents Input-to-output isolation during faults or shutdown Operation down to VIN = 2.5 V with undervoltage lockout (UVLO) at VIN = 2.0 V Available in a small 20-ball, 2.15 mm × 2.36 mm × 0.6 mm WLCSP or a 20-lead, 4 mm × 4 mm × 0.75 mm LFCSP
