I need to control the speed of the FAN,using the PWM output from Arduino ATmega328 MCU and the FG_OUTPUT from FAN is fed to MCU. The FAN is Sunon Fans Part Number is UF385-100.But in FAN Datasheet page no:8, it states that do not use the power or ground PWM to control the FAN Speed.
I have attached the reference schematics used by me which is below
please provide your feedback and any valuable suggestion.
Thanks & Regards,
