Lock Protection
In order to protect the motor, the driver IC will be shutdown to drive the coil when the motor is
locked over 0.3 seconds. Then, it restarts to drive the motor after 2.1 seconds. Figure 1 shows the
timing diagram between the hall input signal and driver's output state.

Rotation Frequency and Detector
This driver IC outputs the FG and RD signal for some special application.
For FG application, the driver IC will generate square wave to indicate the motor
rotation frequency. For RD application, the driver IC will output a high signal to
indicate the stop of the motor and a low signal to indicate the normal operation of
the motor. (See Fig. 1)
Pre-Amplifier
This driver IC integrates signal amplifier and the hysteresis comparator in
this chip. The hysteresis comparator uses the hysteresis characteristic to
eliminate noisy oscillations at output of the comparator.
The driver IC architecture block diagram is shown in Fig. 2.
