WebMay 8, 2024 · The PWM is a wire that essentially connects to a mosfet of some kind, actually within the fan. By default, the fan is drawing some of the 12v to the mosfet itself and thus, by default, it will spin as the mosfet is at a high state. The only way to stop the fan spinning is to make the mosfet change to a low state. Web• A trip condition can force either high, low, or high-impedance state logic levels at PWM outputs. • All events can trigger both CPU interrupts and ADC start of conversion (SOC) • Programmable event prescaling minimizes CPU overhead on interrupts. • PWM chopping by high-frequency carrier signal, useful for pulse transformer gate drives.
