  • BACKWARD PEDALING DETECTION CIRCUIT FOR E-BIKE MOTOR DRIVER
    Publication number: 20090102408
    Abstract: A backward pedaling detection circuit has a charging/discharging circuit for charging and discharging the external capacitor to meet the threshold voltage required by the hysteresis comparator, based on the input from the hall sensor. An internal pull-down circuit, based on the pedal speed, keeps the circuit from false triggering. A comparator with hysteresis (Schmitt trigger) sets the upper and lower threshold voltage and eliminates the effect of noise. AND gates act like switches to allow the selected signal to pass through.
