10-SIP
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.
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

FUNCTIONAL DESCRIPTION
- Forward & Reverse Control Logic
If FIN (pin 5) = ?& RIN (pin 6) = ? load current (IL) flows from VOUT1(pin 2) to VOUT2 (pin 10),
if FIN = ?& RIN = ? load current (IL) flows from VOUT2 to VOUT1.
- Forced Stop Logic
If FIN & RIN
=
?or ? the device stops supplying power to motor while absorbing inverse electromotive
force from the motor as a brake.
- Rush Current Absorbing Circuit
If a high voltage generated during reversing operating is applied across VOUT1 & VOUT2, an internal comparator
activates the rush-current-absorbing-circuit.
- Driving Stage
In the forward mode, the driving stage supplies a load current to the motor from pin 2 to pin 10. 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)
