... MOSFET remains off. This causes V to fall. When V reaches the 5V, the current consumed by FAN100 reduces to the startup current (maximum 10µA) and the current supplied startup resistor charges the V When V reaches the turn-on voltage of 16V, FAN100 DD resumes normal operation. In this manner, the auto- ...
