The LP5523 is a 9-channel LED driver designed to produce lighting effects for mobile devices. A high-efficiency charge pump enables LED driving over full Li-Ion battery voltage range. The device is equipped with an internal program memory, which allows operation without processor control.

The LP5523 maintains excellent efficiency over a wide operating range by autonomously selecting the best charge-pump gain based on LED forward voltage requirements. The LP5523 is able to automatically enter power-save mode when LED outputs are not active, thus lowering idle current consumption down to 10 µA (typical).

The LP5523 has an I2C-compatible control interface with four pin selectable addresses. The device has a flexible general purpose output (GPO), which can be used as a digital control pin for other devices. INT pin can be used to notify processor when a lighting sequence has ended (interrupt function). Also, the device has a trigger input interface, which allows synchronization, for example, between multiple LP5523 devices.

The device requires only four small, low-cost ceramic capacitors. The LP5523 is available in a tiny 25-pin DSBGA package (0.4-mm pitch).

For all available packages, see the orderable addendum at the end of the data sheet.
