Application Note
Rotor lock Toff and PWM signal
When PWM signal input at PWM pin is low for longer than 65ms, internal rotor lock protection Toff is cleared. This allows the
device to enter motor start Ton time on the next PWM high signal
Soft Switching
AH5795 uses soft switching of the motor coil current during commutation for to minimize audible switching noise and
electromagnetic interference (EMI) to provide a low noise solution.
