When the IC drive, serial input while the PS pin applied H voltage. (See the electrical characteristics; P.3, 4, 5/16) 2) Control Input Pin (Ⅰ)IN pin (BD6883GUL, BH6453GUL) The IN pin is used to program and control the motor drive modes. (See the electrical characteristics; P3, 4/16, and the I/O Truth Table; P12/16) (Ⅱ)INA, INB, SEL pins (BD6886GUL, BD6369GUL) The INA and INB are used to program and control the motor drive modes. When the L voltage is applied to the SEL pin, the I/O logic can be set to EN (Enable)/IN mode, and when the H voltage is applied to the one, the I/O logic can be set to IN/IN mode. (See the electrical characteristics; P5/16, and the I/O Truth Table; P12/16) 3) H-bridge and Half-bridge on the output stage (ALL series) Specify maximum current applied to the H-bridge and Half-bridge within the operating range, in consideration of power dissipation. (See the Operating Conditions; P.2/16) 4) Drive system of Linear Constant-Voltage H-bridge (BD6883GUL, BD6886GUL, and BD6369GUL) To set up the output H voltage, when the voltage input to the VLIM pin, the output H voltage is two times as high as the voltage. (Ⅰ)BD6883GUL The output H voltage VOH [V] = 2.0×VLIM [V] (Ⅱ)BD6886GUL, BD6369GUL The output H voltage VOH [V] = 2.0×VLIM [V] (When VLIM [V] > VCC [V] , Output H voltage is about VCC voltage) ・・・・・① 2 (When VLIM [V] > VM [V] , Output H voltage is about VM voltage) 2 ・・・・・② For example, the output voltage is 2.0V±5%, if 1.0V is applied to the VLIM pin. If the VLIM pin is shorted to the VM pin (or the same voltage level as the VM is applied), you can be used as a Full-ON Drive H-bridge. 5) Drive system of Linear Constant-Current H-bridge (BH6453GUL) To detect the output current and the output current settings The BH6453GUL built in resistor for output current detect. The output current is kept constant by comparing it with the CLIM voltage. In addition, impress a highly accurate voltage form the outside of IC to the CLIM terminal, when you do the output current setting accuracy or more good. Output current ISINK [A] = CLIM [V] ・・・・・③ 2×2(Typ) [Ω] If the CLIM pin applied 0.8V, Output current is 200mA±10%. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved. 10/16 2012.03 - Rev.A Technical Note BD6883GUL,BH6453GUL,BD6886GUL,BD6369GUL 7) Setting of PWM signal input VLIM and CLIM terminals (all series) It is also possible to compose filters outside the IC, change an input voltage for output voltage and output current setting terminals such as VLIM and CLIM terminals by the DUTY control using an PWM signal, etc., and use them as set values for control. In this case, however, ensure the smoothing of the signals, heeding the constant number of the low-pass filter as stated below. A cutoff frequency FC (-3dB attenuation frequency) of the low-pass filter in Fig25 is calculated by the formula mentioned below. 1 Cutoff frequency FC [Hz] = [Hz] ・・・・・④ 2πCIN (RINA//RINB) Set the cutoff frequency FC at 1/100 or below of the PWM frequency FPWM.

Assumptions should not be made regarding the state of the IC (short mode or open mode) when such damage is suffered. A physical safety measure, such as a fuse, should be implemented when using the IC at times where the absolute maximum ratings may be exceeded. 2) Storage temperature range (Tstg) As long as the IC is kept within this range, there should be no problems in the IC’s performance. Conversely, extreme temperature changes may result in poor IC performance, even if the changes are within the above range. 3) Power supply and wiring Be sure to connect the power terminals outside the IC. Do not leave them open. Because a return current is generated by a counter electromotive force of the motor, take necessary measures such as putting a Capacitor between the power source and the ground as a passageway for the regenerative current. Be sure to connect a Capacitor of proper capacitance (0.1μF to 10μF) between the power source and the ground at the foot of the IC, and ensure that there is no problem in properties of electrolytic Capacitors such as decrease in capacitance at low temperatures. When the connected power source does not have enough current absorbing capability, there is a possibility that the voltage of the power source line increases by the regenerative current an exceeds the absolute maximum rating of this product and the peripheral circuits. Therefore, be sure to take physical safety measures such as putting a zener diode for a voltage clamp between the power source an the ground. 4) Ground terminal and wiring The potential at GND terminals should be made the lowest under any operating conditions. Ensure that there are no terminals where the potentials are below the potential at GND terminals, including the transient phenomena. The motor ground terminals PGND, and the small signal ground terminal GND are not interconnected with one another inside the IC. It is recommended that you should isolate the large-current RNF pattern and PGND pattern from the small-signal GND pattern, and should establish a one-point grounding at a reference point of the set, to avoid fluctuation of small-signal GND voltages caused by voltage changes due to pattern wire resistances and large currents. Also prevent the voltage variation of the ground wiring patterns of external components. Use short and thick power source and ground wirings to ensure low impedance. 5) Thermal design Use a proper thermal design that allows for a sufficient margin of the power dissipation (Pd) at actual operating conditions. 6) Pin short and wrong direction assembly of the device. Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any connection error or if positive and ground power supply terminals are reversed. The IC may also be damaged if pins are shorted together or are shorted to other circuit’s power lines. 7) Avoiding strong magnetic field Malfunction may occur if the IC is used around a strong magnetic field. 8) ASO Ensure that the output transistors of the motor driver are not driven under excess conditions of the absolute maximum ratings and ASO. 9) TSD (Thermal Shut Down) circuit If the junction temperature (Tjmax) reaches 175°C (but the BH6453GUL is 150°C), the TSD circuit will operate, and the coil output circuit of the motor will open. There is a temperature hysterics of approximately 25°C (but the BH6453GUL is 20°C). The TSD circuit is designed only to shut off the IC in order to prevent runaway thermal operation. It is not designed to protect the IC or guarantee its operation. The performance of the IC’s characteristics is not guaranteed and it is recommended that the device is replaced after the TSD is activated. www.rohm.com © 2012 ROHM Co., Ltd.

Always discharge Capacitors after each process or step. Always turn the IC's power supply off before connecting it to, or removing it from a jig or fixture, during the inspection process. Ground the IC during assembly steps as an antistatic measure. Use similar precaution when transporting and storing the IC. Regarding the input pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements to keep them isolated. P-N junctions are formed at the intersection of these P layers with the 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, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic diode and transistor. Parasitic elements can occur inevitably in the structure of the IC. The operation of parasitic elements can result in mutual interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic elements operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be used.
