Reversible Motor Drivers for Brush Motors
2.0A or More Reversible
Motor Drivers (Single Motor)
BA6219BFP-Y,BA6222
No.11008EBT03
Description
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.
Features
1) Large output current (lOMAX=2.2A)
2) Built-in thermal shutdown circuit
3) Output voltage can be optionally set by reference voltage setting pin
4) High output voltage can be set by low voltage input because of it has 11.4dB gain (BA6222)
5) Low standby current
Applications
Audio-visual equipment; PC peripherals; Car audios; Car navigation systems; OA equipments

Technical Note
External application components
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 10. 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.
Functional descriptions
1) Operation modes
Table 3 Logic table
IN1 IN2 OUT1 OUT2
Operation
L L OPEN* OPEN* Stop (idling)
H L H L Forward (OUT1 > OUT2)
L H L H Reverse (OUT1 < OUT2)
H H L L Brake (stop)
*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).

Notice
Precaution on using ROHM Products
1. Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment,
OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you
intend to use our Products in devices requiring extremely high reliability (such as medical equipment (Note 1), transport
equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car
accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bodily injury or
serious damage to property (“Specific Applications”), please consult with the ROHM sales representative in advance.
Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any
damages, expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for Specific
Applications.

2. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which
a failure or malfunction of our Products may cause. The following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3. Our Products are designed and manufactured for use under standard conditions and not under any special or
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any
special or extraordinary environments or conditions. If you intend to use our Products under any special or
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of
product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,
H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items
[f] Sealing or coating our Products with resin or other coating materials
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning
residue after soldering
[h] Use of the Products in places subject to dew condensation
4. The Products are not subject to radiation-proof design.
5. Please verify and confirm characteristics of the final or mounted products in using the Products.
6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual
ambient temperature.
8. Confirm that operation temperature is within the specified range described in the product specification.
9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in
this document.
Precaution for Mounting / Circuit board design
1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product
performance and reliability.
2. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the
ROHM representative in advance.
For details, please refer to ROHM Mounting specification
