Low Voltage Fan Driver

This fan demo that we developed is based on NM18002Y. NM18002Y is composed of 8051 and 30V PN gate drivers. There are built-in comparators and 5V LDO, which can help users save PCB space and cost. A microcontroller can quickly expand various peripheral functions compared to the general ASIC IC. Based on this example, users can complete projects more quickly.
