Analog Devices ADP8861 LED Driver Datasheet
The ADP8861 is a 7‑channel smart LED driver that provides independent control of up to seven LEDs. Each channel can be programmed for current limit and fade‑in/out timing, with selectable charge‑pump gains of 1×, 1.5×, or 2× for high efficiency. The device includes standby mode with sub‑µA quiescent current, soft‑start, and input‑to‑output isolation during faults.
Typical applications include mobile display and keypad backlighting, dual‑RGB backlighting, LED indication, and general backlighting of small‑format displays. The part is offered in a 20‑ball WLCSP package (2.15 mm × 2.36 mm × 0.6 mm) or a 20‑lead LFCSP package (4 mm × 4 mm × 0.75 mm).
