APPLICATION INFORMATION
1. HALL INPUT
The input signal of the Hall Sensor requires more amplitude than 100mVo-p. and the operating voltage
level of the Hall Sensor is from 1.2V~VCC1-0.8V.
VCC1
More than 1.7V

6
More than 100mVo-p
More than 1.3V
2. OUTPUT CURRENT DETECTION
Pin 11 is usually connected with Rs(approx. 0.5 ), and the motor current is converted to a voltage by
the Rs and provided to a feedback amplifier. Pin 12 is connected to the circuit with the ground side or Rs.

3. MOTOR SPEED CONTROL(INPUT CURRENT LIMITATION)
The maxmum output current is limitted by Pin 19 voltage as follows. So a motor speed is controlled by
the output current. In case of no-use, it is to be short-circuit with VCC1
.

4. MOTOR SPEED CONTROL(INPUT VOLTAGE CONTROL )
The control of motor speed is possible on the conditions of VCTL(Pin 20) VREF
The control gain is approx. 1.0 A/V as follows.

8. FG AMP
These amplifiers are the inversion type. One amplifier is built in both the reference voltage(approx. 2.5V)
and the gain setting resistors. The voltage gain ia approx. 31 times.
