This example is for fan that we developed base on NM1817. NM1817 is composed of M0 and a 600V gate driver. There is built-in comparator and 5V LDO, which can help users save PCB space and cost. Besides, various peripheral function can be easily expanded with the microcontroller . Based on the example, users can complete project more quickly.
