| KA8330 LOADING MOTOR DRIVER The KA8330 is a monolitic integrated circuit designed to perform bi-directional DC motor driving, braking and speed control for VCRs , CDPs, and Toys. The speed control can be achieved by adjusting the external voltage of the motor speed control pin. And it has two pins of logic inputs for controlling the direction such as forward/reverse and braking. LOADING MOTOR DRIVER 10-SIP FEATURES * Stable braking characteristics by built-in braking function * Built-in element to absorb dash current derived from changing motor direction and braking motor driving * Built-in external motor speed control pin * Stable driving direction change * CMOS logic level compatible input level TYPICAL APPLICATIONS * VCR * CDP * TOY ORDERING INFORMATION Device KA8330 Package 10-SIP Operating Temperature -25I ~ +75I BLOCK DIAGRAM DRIVER PRE LOGIC 1 2 3 4 5 6 7 8 9 10 GND VOUT 1 VZ 1 VR FIN RIN VCC 1 VCC 2 VZ 2 VOUT 2 1 KA8330 PIN DESCRIPTION Pin No. 1 2 3 4 5 6 7 8 9 10 Symbol GND VOUT 1 VZ 1 VR FIN RIN VCC 1 VCC 2 VZ 2 VOUT 2 I/O LOADING MOTOR DRIVER Description Ground Motor drive output 1 Capacitor connection Motor speed control pin.

In the reverse mode, it supplies the current from pin 10 to pin 2. The output voltage VOUT applied to the motor is given by the following method : VOUT(V) = VZD - VCE(SAT) VZD : Zener Voltage applied to pin 4. If pin 4 is left open, the output voltage is given by the following method : VOUT(V) = VCC1 - VCE(SAT PNP) - 2VBE -VCE(SAT) 4 KA8330 TEST CIRCUIT LOADING MOTOR DRIVER KA8330 GND VOUT 1 VZ 1 1 2 3 VR 4 FIN 5 RIN 6 VCC 1 VCC 2 7 8 VZ 2 9 VOUT 2 10 CD 0.1O S3 S1 S2 S4 RL 60U S7 A A S5 ZD 7.4V 5 A S6 VIN A RC 10U VCC Table 1.
