This example is for fan that we developed base on NM18002Y. NM18002Y is composed of 8051 and 30V PN gate driver. There are built-in comparators and 5V LDO, which can help users save PCB space and cost. Compared with the general ASIC IC, various peripheral function can be easily expanded with microcontroller. Based on this example, users can complete project more quickly.
