The MAX7221EWG+ is an integrated circuit developed by Analog Devices that is a constant current discharge, 8-bump WLP (Wafer Level Package) LED driver. It features an 8-bit current sink output that allows user adjustable current level, suitable for driving current up to 25 mA. The wide input voltage range of 4.5 V to 5.5 V and internal regulation allow it to operate from a single supply and provide a pixel level of brightness control. It offers operational modes such as scan limit, blanking, and display testing to meet the requirements for time-multiplexed LED display applications. Additionally, it is AEC-Q100 qualified, making it suitable for automotive applications.
