ADP8866ACPZ-R7

ADP8866 is a charge pump driven 9-channel LED driver with automated LED lighting effects. It combines a programmable backlight LED charge pump driver with automatic blinking functions. Nine LED drivers can be independently programmed at currents up to 25mA. The current level, fade time, and blinking rate can be programmed once and executed autonomously on a loop. Separate fade-in and fade-out times can be set for the backlight LEDs. Driving all of this is a two-capacitor charge pump with gains of 1×, 1.5×, and 2×. A full suite of safety features including short-circuit, overvoltage, and over temperature protection allows easy implementation of a safe and robust design. Additionally, input inrush currents are limited via an integrated soft start combined with controlled input to output isolation. Application includes mobile display backlighting, mobile phone keypad backlighting, LED indication and status lights, automated LED blinking.

• 9 independent and programmable LED drivers, each driver is capable of 25mA (full scale)
• Each driver has 7bits (128 levels) of nonlinear current settings
• Standby mode for <lt/>1µA current consumption, automated and customizable LED blinking
• PWM input for implementing content adjustable brightness control (cABC)
• I²C compatible interface for all programming
• Dedicated reset pin and built-in power on reset (POR)
• Short circuit, overvoltage, and over temperature protection
• Internal soft start to limit inrush currents, input to output isolation during faults or shutdown
• Operating range from 2.5 to 5.5V (VIN=3.6V, SCL=2.7V, SDA=2.7V2, TJ=-40 to +105°C)
• 20-Lead LFCSP package, temperature range from -40°C to +105°C
