APPLICATION INFORMATION
1. HALL INPUT
VCR PRODUCTS
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 1 3 5 2 4 6 More than 100mVo-p
More than 1.3V
2. OUTPUT CURRENT DETECTION
www..com
Pin 11 is usually connected with Rs(approx. 0.5a), 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)
VCR PRODUCTS
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. GML=Io/VLIM=(Io2-Io1)/(VLIM2-VLIM1), where VLIM1=1.45V => Output current=Io1 VLIM2=1.55V => Output current=Io2
