during storage or handling to prevent electrostatic damage to the MOS gates.
DESCRIPTION (CONTINUED)
The LP55231 has an I²C-compatible control interface with four pin selectable addresses. 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 LP55231 devices.
The device requires only four small and low-cost ceramic capacitors. The LP55231 is available in a 24-pin
WQFN package.
