The driver IC architecture block diagram is shown in Fig. 2
Ver.1.5
Rotation Detector
This driver IC output the RD signal for some special application. For RD
application, the driver IC will output high to indicate the motor is stop and low
to indicate the motor is normal operation.

Lock Protection
In order to protect the motor, the driver IC will stop to drive the coil when
the motor is locked over 0.4 seconds. Then, it restarts to drive the motor after
2.8 seconds. Figure 1 shows the timing diagram between the hall input signal
and driver's output state.
