External application components 1) Resistor for the current limitation, R1 This is a current limiting resistor for collector loss reducti on 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 Ω. 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 1 μF to 100 μF 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 delayin g base potential buildup of transistors which enter output high state. Set the capacitors from 0.01μF to 1 μF 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 0.01 μF to 0.1 μF 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).

BA6219BFP-Y,BA6222 2) Output high voltage setting This function optionally sets output voltage by the output high voltage setting pin and controls the motor rotating speed. However, when the output high voltage is set to a low level, consumption at IC increases. Carry out thermal design with sufficient margin incorporated with the power dissipation (Pd) under the actual application condition taken into account. a) BA6219BFP-Y The circuit diagram associated with the output high voltage setting VR pin is as per shown on the right. The maximum output voltage VOMAX is expressed by: VOMAX = VCC1 - ( VSAT(Q1) + VF(Q2) + VF(Q3) + VF(Q4) ) In addition, the relation of VR voltage to output voltage at VOMAX or lower is expressed by: VOH = VR + ( VF(Q5) + VF(Q6) + VF(Q7) ) - ( VF(Q2) + VF(Q3) + VF(Q4) ) VOH = VR + ΔVF ≈ VR ΔVF depends on the output current but is nearly VOH=VR. (Reference values; VSAT ≈ 0.25V, VF ≈ 0.75V) b) BA6222 As the relationship between the output high voltage setting pin VR voltage and output high voltage V OH is expressed by: V OH ≈ 4 x VR + VOFS In such event, V OFS means the offset voltage, which varies in accord with output current and chip temperature. The VR voltage region can be classified into three categories in accord with the output state: (A) Output high voltage 0V offset region (B) Fourfold gain region (C) Output voltage saturated region Using this function with the VR pin connected to a load which has output impedance of several hundred ohms may result in oscillation. In such event, connect a capacitor of 3300pF or higher to about 0.1 μF across VR and GND and make sure that the motor is free of oscillation. c) Power supply voltage range of VR voltage When output voltage control pin (VR) is used: VR < VCC1 - ( V SAT(Q1) + VF(Q5) + VF(Q6) + VF(Q7) ) VR ≈ VCC1 - 2.5V VR < VCC2 - ( VSAT(Q3) - VF(Q3) - VF(Q2) ) - ( VF(Q5) + VF(Q6) + VF(Q7) ) VR ≈ VCC2 - 1V The output voltage control function does not operate in the region outside this range. In addition, when the VR pin is not used, use by shorting VR to VCC1. 3) Switching of rotating direction (FWD/REV) When the rotating direction is changed over by the motor rota ting condition, switch the direction after the motor is temporarily brought to the BRAKE condition or OPEN condition. It is recommended to keep the relevant conditions as follows: via BRAKE: Longer than braking time*. (* the time required for the output L terminal to achieve potential below GND when brake is activated.) via OPEN: The time longer than 1 ms is recommended.

Notes for use 1) Absolute maximum ratings Devices may be destroyed when supply voltage or operating temperature exceeds the absolute maximum rating. Because the cause of this damage cannot be identified as, for example, a short circuit or an open circuit, it is important to consider circuit protection measures – such as adding fu ses – if any value in excess of absolute maximum ratings is to be implemented. 2) Connecting the power supply connector backward Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply lines, such as adding an external direction diode. 3) Power supply lines Return current generated by the motor’s Back-EMF requires countermeasures, such as providing a return current path by inserting capacitors across the power supply and GND ( 10µF, ceramic capacitor is recommended). In this case, it is important to conclusively confirm that none of the negative effects sometimes seen with electrolytic capacitors – including a capacitance drop at low temperatures - occu rs. Also, the connected power supply must have sufficient current absorbing capability. Otherwise, the regenerated curr ent will increase voltage on the power supply line, which may in turn cause problems with the product, including peripheral circuits exceeding the absolute maximum rating. To help protect against damage or degradation, physical safety measures should be taken, such as providing a voltage clamping diode across the power supply and GND. 4) Electrical potential at GND Keep the GND terminal potential to the minimum potential under any operating condition. In addition, check to determine whether there is any terminal that provides voltage below GND, including the voltage during transient phenomena. When both a small signal GND and high current GND are present, single-point grounding (at the set’s reference point) is recommended, in order to separate t he small signal and high current GND, and to ensure that voltage changes due to the wiring resistance and high current do not affect the voltage at the small signal GND. In the same way, care must be taken to avoid changes in the GND wire pattern in any external connected component. 5) Thermal design Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) under actual operating conditions. 6) Inter-pin shorts and mounting errors Use caution when positioning the IC fo r mounting on printed circuit boards. The IC may be damaged if there is any connection error, or if pins are shorted together. 7) Operation in strong electromagnetic fields Using this product in strong electromagnetic fields may cause IC malfunctions. Use extreme caution with electromagnetic fields. 8) ASO - Area of Safety Operation When using the IC, set the output transistor so that it does not exceed absolute maximum ratings or ASO. 9) Built-in thermal shutdown (TSD) circuit The TSD circuit is designed only to shut the IC off to prev ent thermal runaway. It is not designed to protect the IC or guarantee its operation in the presence of extreme heat. Do not continue to use the IC after the TSD circuit is activated, and do not operate the IC in an environment where activation of the circuit is assumed. BA6219BFP-Y BA6222 TON [℃] 180 150 THYS [℃] 15 15 *All temperature values are typical. 10) Capacitor between output and GND In the event a large capacitor is connected between the output and GND, if VCC and VIN are short-circuited with 0V or GND for any reason, the current charged in the capacitor flows into the output and may destroy the IC. Use a capacitor smaller than 1μF between output and GND.

BA6219BFP-Y,BA6222 11) Testing on application boards When testing the IC on an application board, connecting a capaci tor to a low impedance pin subjects the IC to stress. Therefore, always discharge capacitors after each process or step. Always turn the IC's power supply off before connecting it to or removing it from t he test setup during the inspection proc ess. Ground the IC during assembly steps as an antistatic measure. Use similar precaution when transporting or storing the IC. 12) Regarding the input pin of the IC This monolithic IC contains P+ isolat ion and P substrate layers between adjac ent elements, in order to keep them isolated. P-N junctions are formed at the intersection of these P layers with t he N layers of other elements, creating a parasitic diode or transistor. For example, the relation between each potential is as follows: When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, as well as operating malfunctions and physical damage. Therefore, do not use methods by which parasitic diodes operate, such as applying a voltage lower than the GND (P substrate) voltage to an input pin.
