These motor drivers are full bridge drivers for brush motor applications, supporting output currents of up to 2A. The output
modes are available in four modes, normal, reverse, stop (idling), and braking in accordance with input logic (2 inputs). The
output voltage can be optionally set by reference voltage setting pin.
No.09008EAT03
Features
1) Large output current (l

External application components
Technical Note
1) Resistor for the current limitation, R1
This is a current limiting resistor for collector loss reduction and at the time of short-circuited output. It depends on the
power supply voltage used, etc., but choose resistance of about 5 to 10Ω. In addition, set resistance with utmost care
to voltage drop caused by inrush current that flows when the motor is started.
2) Zener diode for the output high voltage setting, ZD
This is the zener diode used when output high voltage (VR pin voltage) is set.
BA6219BFP-Y: Output high voltage
≈
zener voltage
BA6222: Output high voltage
≈
fourfold zener voltage
3) Stabilization capacitor for the power supply line, C1
Please connect the capacitor of 1μF to 100μF for the stabilization of the power supply line, and confirm the motor
operation.
4) Capacitors for the cross conduction control of output transistors, C2 and C3
Simultaneous ON is prevented by delaying base potential buildup of transistors which enter output high state. Set the
capacitors from 0.01μF to 1μF and make sure inrush current caused by simultaneous output ON does not flow when
output mode is switched.
5) Phase compensating capacitor, C4
Noise is generated in output pins or oscillation results in accord with the set mounting state such as power supply
circuit, motor characteristics, PCB pattern artwork, etc. As noise oscillation measures, connect 0.01μF to 0.1μF
capacitors.
6) Phase compensating capacitor, C5 (BA6222 only)
The gain about fourfold VR pin voltage in output high voltage is set, and the output oscillates easily. Please connect the
capacitor of 3300pF to 0.1µF as an oscillation prevention measures when the oscillation is seen in the output voltage.

* OPEN is the off state of all output transistors. Please note that this is the state of the connected diodes, which differs from that of the mechanical relay.
a) Stand-by mode
In stand-by mode, all output power transistors are turned off, and the motor output goes to high impedance.
b) Forward mode
This operating mode is defined as the forward rotation of the motor when the OUT1 pin is high and OUT2 pin is low.
When the motor is connected between the OUT1 and OUT2 pins, the current flows from OUT1 to OUT2.
c) Reverse mode
This operating mode is defined as the reverse rotation of the motor when the OUT1 pin is low and OUT2 pin is high.
When the motor is connected between the OUT1 and OUT2 pins, the current flows from OUT2 to OUT1.
d) Brake mode
This operating mode is used to quickly stop the motor (short circuit brake).
