A motor lock condition is detected when the Hall signal stops switching. The output is ON when CT pin is being charged. C2 is the external capacitor of the CT pin. Output ON time and OFF time are determined by the capacitan ce of C2. Note 6: RD pin is ON during normal operation, and OFF when the motor is locked. It is an open collector output pin. .)()(*2 SecI VVCT CHG CPCL ON .)()(*2 SecI VVCT DHG CPCL OFF Note 7: The RD pin may maintain HIGH level for a few hundred milliseconds when the power is turn ed on.
