• Periphery circuit is composed of bipolar, KSB722 and one 100µF capacitor. The capacitor needs good
temperature characteristics to remove the ripple.
•The output voltage VOUT is decided by the following formula:
VOUT = VREF BG (R2 + R3) / R3 = 2.5 X 2 = 5V
R2 = R3
3. LOADING MOTOR DRIVER

•Input voltage (5V and 0V or 0V and 5V to pin 9 and pin 14.
•After input the voltage to pin 9 and pin 14, decide the output of comparator according to the voltage state.
•As the above figure, the voltage warp ∆V, [VREF1 + (I x R)] - [VREF1 -(I x R)], used for the motor. And the
direction of the motor is decided by the voltage warp +∆V and -∆V.
•The output characteristics are as follows:

•If the torque of the loading motor is too low when it is used with the pin #20 open, then it should be used as the
above diagram.
•The desired torque could be obtained by selecting the appropriate resistor R as shown in the left diagram.
•If it is necessary, the zener diode can be used as in the right diagram.
•The maximum torque is obtained when the applied voltage at pin #20 is about 6.8V (at VCC=8V).
5. Connect a by-pass capacitor, 0.1µF between the supply voltage source.
