Technical Note
1) Power-saving and Serial Reset (BD6370GUL; PS) (1) Function Explanation When Low-level voltage is applied to PS pin, the IC will be turned off internally and the circuit current will be 0μA (Typ.). During operating mode, PS pin should be High-level. (See the Electrical Characteristics; p.2/32) Be cancelled power saving mode after turned on power supply VCC and VM, because of PS terminal combines power saving with serial reset function. If the case of power saving terminal always shorted power supply terminal, reset function may not be well, and it may cause the IC to malfunction. (See the Sequence of Serial Control Input; p.12/32) 2) Motor Control Input (BD6370GUL; INPUTx) (1) Function Explanation These pins are used to program and control the motor drive modes. So INPUTx switches CW or CCW, CW or Brake, and CCW or Brake, using serial function. (See the Electrical Characteristics; p.2/32 and I/O Truth Table; p.21/32 to p.23/32) INPUT34 and INPUT45 pins drive ch3 or ch4, and ch4 or ch5, respectively. The driven channel is selected using serial function. (See the Driven Outputs for INPUT Terminal Table; p.14/32) 3) H-bridge (BD6370GUL; VM, OUTxA, OUTxB, and RNFx) (1) Function Explanation The H-bridge output transistors of BD6370GUL are Power CMOS Drivers. The total H-bridge ON-Resistance on the high and low sides varies with the VM voltage. The system must be designed so that the maximum H-bridge current for each channel is 500mA or below. The 3 H-bridges of ch1 to ch3 can be driven as the resemblance 4-channels. For this reason, it is possible to drive the 2 Stepping Motors by ch1 to ch3 as long as the 2 motors don’t move simultaneously. The selection of resemblance drive mode for ch1 to ch3 is set using serial function. (See the Driven Outputs for INPUT Terminal Table; p.14/32) The 2 control input terminals of INPUT34 and INPUT45 drive the 3 H-bridges of ch3 to ch5. Use caution because it is impossible to drive all 3 H-bridges simultaneously. (2) The D/A Converter Settings of Constant-Voltage, Constant-Current, and Full-ON Mode The ch1 to ch3 enable Constant-Voltage or Full-ON Driving, and the ch4 enables Constant-Voltage, Constant-Current, or Full-ON Driving, while the ch5 is Constant-Current Driving. In the case of Full-ON mode for ch1 to ch3, input serial data of each Constant-Voltage setting D/A Converter (DAC12 and DAC3) to be full bits high. In the ch4, as it set Constant-Voltage mode, input serial data of Constant-Current setting D/A Converter (DACI4) to be full bits high. As it set Constant-Current mode, input serial data of Constant-Voltage setting D/A Converter (DACV4) to be full bits high, while as it set Full-ON mode, input serial data of both D/A Converters to be full bits high. In the settings of Constant-Voltage or Full-ON mode, no need to connect the external resistance for output current detection in RNF4 pin. The selection of drive mode for ch1 to ch4 is set using serial function. (See the serial settings of the drive mode in each channel; p.13/32 and p.15/32) (a) Constant-Voltage mode (ch1 to ch4) (8×VDACx≦VM[V], x = 12, 3, and V4) ･･････(1) Output high voltage; VVOHx[V] = 8×VDACx[V] VVOHx[V] = VM[V] (8×VDACx＞VM[V], x = 12, 3, and V4) ･･････(2) D/A Converter setting value; 8×VDACx[V] = 1.5 to 4.725 (DACx = 6’b01_0100 to 6’b11_1111, x = 12, 3, and V4) In the ch4, set DACI4 = 6’b11_1111. (b) Constant-Current mode (ch4 and ch5) (x = I4 and 5) ･･････(3) Output current; Ioutx[A] = VDACx[V]÷(RMETALx[Ω]＋RRNFx[Ω]) D/A Converter setting value; VDACx[V] = 0.05 to 0.315 (DACx = 6’b00_1010 to 6’b11_1111, x = I4 and 5) RMETALx; metal impedance of BD6370GUL’s inside (ch4; RMETALI4[Ω] = 0.004(Typ.), ch5; RMETAL5[Ω] = 0.022(Typ.)) RRNFx; Resistance to connect RNFx pin for output current detection In the ch4, set DACV4 = 6’b11_1111. (c) Full-ON mode (ch1 to ch4) D/A Converter setting value; DACx = 6’b11_1111

4) Serial Input (BD6370GUL; STROBE, SCLK, and SDATA) (1) Function Explanation The BD6370GUL provides a 3-line serial interface for setting output modes and D/A converters. SDATA is sent to the internal shift register during the STROBE low interval at the SCLK rising edge. Shift register data (Bit[B] to Bit[0]) is written to the IC's internal 12-bit memory at the STROBE rising edge, according to the addresses stored in Bit[E], Bit[D], and Bit[C]. The serial data input order is Bit[E] to Bit[0]. In the case of the resemblance drive mode (MODE13=1 and/or MODE23=1), input the serial data to be the same condition of DAC12 and DAC3. Be cancelled power saving mode after turned on power supply VCC and VM. Serial settings are reset when the PS pin changes to Low-level control voltage, because of PS terminal combines power saving with serial reset function. Serial settings are also reset when the UVLO or TSD circuit operates.

In the same condition, MODE12B, MODE12A, IN2B, and IN2A bits, and INPUT2 terminal drive OUT2A-OUT3B. And set the serial data as DAC12 = DAC3, if not, Output high voltage is different value between OUT1A and OUT3A, and/or OUT2A and OUT3B.

Fig.50 BD6758MWV / KN Application Circuit Diagram 1) Power-saving function (BD6758MWV / KN) When Low-level voltage is applied to PS pin, the IC will be turned off internally and the circuit current will be 0μA (Typ.). During operating mode, PS pin should be High-level. (See the Electrical Characteristics; p.6/32) 2) Control input (BD6758MWV / KN) (1) INxA, INxB, EN1 and IN5 pins These pins are used to program and control the motor drive modes. (See the Electrical Characteristics; p.6/32 and I/O Truth Table; p.28/32) (2) SELx pins When the Low-level voltage is applied to the SEL pin, the I/O logic can be set to EN/IN mode. However, when the High-level voltage is applied, the I/O logic can be set to IN/IN mode. (See the Electrical Characteristics; p.6/32 and I/O Truth Table; p.28/32) (3) BRKx pins Applying the High-level voltage to the BRKx pin will set the brake mode. (See the Electrical Characteristics; p.6/32 and I/O Truth Table; p.28/32) 3) H-bridge (BD6758MWV / KN) The 5-channel H-bridges can be controlled independently. For this reason, it is possible to drive the H-bridges simultaneously, as long as the package thermal tolerances are not exceeded. The H-bridge output transistors of BD6758MWV and BD6758KN are Power CMOS Drivers. The total H-bridge ON-Resistance on the high and low sides varies with the VM voltage. The system must be designed so that the maximum H-bridge current for each channel is 800mA or below. (See the Operating Conditions; p.2/32)

Technical Note
4) Drive system of Linear Constant-Current H-bridge (BD6758MWV / KN: ch5) BD6758MWV / KN (ch5) enable Linear Constant-Current Driving. (1) Reference voltage output (with a tolerance of ±3%) The VREF pin outputs 1.2V, based on the internal reference voltage. The output current of the Constant-Current Drive block is controllable by connecting external resistance to the VREF pin of the IC and applying a voltage divided by the resistor to the output current setting pins (VLIM pin). It is recommended to set the external resistance to 2kΩ or above in consideration of the current capacity of the VREF pin, and 20kΩ or below in order to minimize the fluctuation of the set value caused by the base current of the internal transistor of the IC. (2) Output current detection and current settings By connecting external resistor (0.1Ω to 5.0Ω) to the RNF pin of the IC, the motor drive current will be converted into voltage in order to be detected. The output current is kept constant by shorting the RNF and SENSE pins and comparing the voltage with the VLIM voltage. To perform output current settings more precisely, trim the external RNF resistance if needed, and supply a precise voltage externally to the VLIM pin of the IC. In that case, open the VREF pin. Output current value VLIM[V] RNF[Ω]
The output current is 400mA3% if 0.2V is applied to the VLIM pin and a 0.5Ω resistor is connected externally to the RNF pin. If the VLIM pin is shorted to the VCC pin (or the same voltage level as the VCC is applied) and the SENSE and RNF pins are shorted to the ground, this channel can be used as a Full-ON Drive H-bridge like the other four channels of BD6758KN. 5) I/O truth table (BD6758MWV / KN) BD6758MWV / KN Full-ON Driver ch1 and ch2 I/O Truth Table INPUT OUTPUT SEL1 INxA INxB OUTxA OUTxB H X Z Z L L L H L L H L H L L Z Z H L H L H L H L H H H L L

Fig.52 BD6758MWV / KN I/O Circuit Diagram (Resistance values are typical ones) ●Notes for use 1) Absolute maximum ratings Use of the IC in excess of absolute maximum ratings such as the applied voltage or operating temperature range may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when such damage is suffered. The implementation of a physical safety measure such as a fuse should be considered when use of the IC in a special mode where the absolute maximum ratings may be exceeded is anticipated. 2) Storage temperature range 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 pins and lines None of the VM line for the H-bridges is internally connected to the VCC power supply line, which is only for the control logic or analog circuit. Therefore, the VM and VCC lines can be driven at different voltages. Although these lines can be connected to a common power supply, do not open the power supply pin but connect it to the power supply externally. Regenerated current may flow as a result of the motor's back electromotive force. Insert capacitors between the power supply and ground pins to serve as a route for regenerated current. Determine the capacitance in full consideration of all the characteristics of the electrolytic capacitor, because the electrolytic capacitor may loose some capacitance at low temperatures. If the connected power supply does not have sufficient current absorption capacity, regenerative current will cause the voltage on the power supply line to rise, which combined with the product and its peripheral circuitry may exceed the absolute maximum ratings. It is recommended to implement a physical safety measure such as the insertion of a voltage clamp diode between the power supply and ground pins. For this IC with several power supplies and a part consists of the CMOS block, it is possible that rush current may flow instantaneously due to the internal powering sequence and delays, and to the unstable internal logic, respectively. Therefore, give special consideration to power coupling capacitance, width of power and ground wirings, and routing of wiring. 4) Ground pins and lines Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the GND at any time, regardless of whether it is a transient signal or not. When using both small signal GND and large current MGND patterns, it is recommended to isolate the two ground patterns, placing a single ground point at the application's reference point so that the pattern wiring resistance and voltage variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to change the GND wiring pattern of any external components, either. The power supply and ground lines must be as short and thick as possible to reduce line impedance. 5) Thermal design Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions.

Technical Note
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) Actions in strong magnetic field Use caution when using the IC in the presence of a strong magnetic field as doing so may cause the IC to malfunction. 8) ASO When using the IC, set the output transistor for the motor so that it does not exceed absolute maximum ratings or ASO. 9) Thermal shutdown circuit If the junction temperature (Tjmax) reaches 175°C, the TSD circuit will operate, and the coil output circuit of the motor will open. There is a temperature hysteresis of approximately 25°C (BD6373GW and BD6873KN Typ.) and 25°C (BD6753KV Typ.). 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. 10) Serial data input In the BD6370GUL, SDATA input string start with MSB first. A low level should be input to the TEST bit at all times. A high signal may cause the IC to malfunction. The serial settings are reset during standby mode operation and whenever the UVLO or TSD circuits are operating. It is the prohibited bit of MODExx input. Don’t input the prohibited bit at all times. (See the Serial Register Bit Map; p.12/32) In the case of the resemblance drive mode (MODE13=1 and/or MODE23=1), MODE3B, MODE3A, IN3B, and IN3A bits are “don’t care”. Because OUT1A-OUT3A is driven by MODE12B, MODE12A, IN1B, and IN1A bits, and INPUT1 terminal control. In the same condition, MODE12B, MODE12A, IN2B, and IN2A bits, and INPUT2 terminal drive OUT2A-OUT3B. And set the serial data as DAC12 = DAC3, if not, Output high voltage is different value between OUT1A and OUT3A, and/or OUT2A and OUT3B. In the case of Full-ON mode for ch1 to ch3,input serial data of each Constant-Voltage setting D/A Converter (DAC12 and DAC3) to be full bits high. In the ch4, as it set Constant-Voltage mode, input serial data of Constant-Current setting D/A Converter (DACI4) to be full bits high. As it set Constant-Current mode, input serial data of Constant-Voltage setting D/A Converter (DACV4) to be full bits high, while as it set Full-ON mode, input serial data of both D/A Converters to be full bits high. In the settings of Constant-Voltage or Full-ON mode, no need to connect the external resistance for output current detection in RNF4 pin. 11) Power saving terminal Be cancelled power saving mode after turned on power supply VCC and VM, because of PS terminal combines power saving with serial reset function. If the case of power saving terminal always shorted power supply terminal, reset function may not be well, and it may cause the IC to malfunction. 12) Testing on application board When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress. 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. 13) Application example The application circuit is recommended for use. Make sure to confirm the adequacy of the characteristics. When using the circuit with changes to the external circuit constants, make sure to leave an adequate margin for external components including static and transitional characteristics as well as dispersion of the IC. 14) Regarding 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.
