LP8501TME/NOPB-Multi-Purpose 9-Output LED Driver

The LP8501 is an LED driver with 9 outputs, designed to produce versatile lighting effects for mobile devices. The device is equipped with an internal program memory, which allows operation without processor control. Internal program memory is used by three independent program execution engines to produce user-defined lighting effects for the outputs.

A high-efficiency charge pump enables LED driving over full Li-Ion battery voltage range. The excellent efficiency over a wide operating range is achieved by autonomously selecting the best charge pump gain based on LED forward voltage requirements. The LP8501 is able to automatically enter power-save mode when LED outputs are not active, thus lowering idle current consumption down to 10 µA (typ.)

The device has a flexible General Purpose Output (GPO) (which can be used, for example, as a digital control pin for other devices), an INT pin (interrupt function), which can be used to notify the processor, and a Trigger input interface, which allows program execution start without I2C write.

The device requires only four small and low-cost ceramic capacitors. The LP8501 is available in a tiny 25-bump 2.26 mm x 2.26 mm x 0.60 mm DSBGA package (0.4 mm pitch).
