The ADP8866 is a charge pump-driven 9-channel LED driver with automated LED lighting effects
The ADP8866 combines a charge‑pump based LED driver with automatic gain selection (1×, 1.5×, 2×) to deliver up to 25 mA per channel across nine independent LED outputs. It supports I²C programming, PWM dimming, and a range of automated lighting effects such as fade‑in/out, heartbeat and custom blinking patterns.
Typical applications include mobile display backlighting, keypad illumination and status LEDs. The device operates from 2.5 V to 5.5 V supply, includes built‑in protections (short‑circuit, over‑voltage, thermal shutdown) and features a low‑standby current of less than 1 µA, making it suitable for battery‑powered designs.
