Note 3: The automatic restart circuit detects a motor lock condition and automatically turns off the output current. When the
lock is cleared, the IC automatically restarts and allows the motor to run. In AH478, automatic restart is performed in the fol-
lowing manner. A motor lock condition is detected when the Hall signal stops switching. The output is ON when CT pin is
being charged, and OFF when CT pin is being discharged.
Output ON time (TON) and OFF time (TOFF) are determined by C, the capacitance of the CT pin external capacitor.
VCL is the CT pin clamp voltage
VCP is the CT pin comparator voltage
ICHG is the CT pin charge current
IDHG is the CT pin discharge current
