The ciruit is a high current fan controller. I'm seeking a qualified/seasoned professional to provide an in-depth review of my circuit design and layout. There is a problem with the design. The driver sometimes doesn't turn on when triggered. The circuit works as follows: A mirocontroller has a triger input Once the input goes high, the MCU outputs a PWM that is fed to a gate driver, that in turn powers the gate of a high power mosfet. This is how the fan speed is controlled. The task entails: - Evaluating the current state of the design, layout and circuit components. - Providing fresh, actionable insights to improve the overall function and efficiency of the circuit design. - Go through the circuit layout and suggest possible tweaks for enhanced performance. - EMI upgrade recomendations Please note, there aren't any specific constraints on the design. Your expertise in the field are what matter most.
