Technical Note
BD6370GUL, BD6758MWV, BD6758KN
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.

Gray lines are prohibition serial bit; don’t input their bits at all times
ATTENTION in the case of resemblance drive mode (MODE23=1 and/or MODE13=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.

At CW, current flows from OUT2A to OUT3B. At CCW, current flows from OUT3B to OUT2A.
ATTENTION in the case of resemblance drive mode (MODE23=1 and/or MODE13=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.

7) The More Precise Constant-Current Settings (BD6370GUL)
Regarding Constant-Current Drive blocks (ch4 and ch5), there is the metal impedance of each RNF in BD6370GUL inside:
4mΩ (Typ.) and 22mΩ (Typ.), respectively. Then the metal impedances and the board patterning impedances of RNF4 and
RNF5 lines considered, set each D/A Converter to drive the actuator in the more precise constant current.

(ex.) If there are VDACx=0.1[V], RRNFx=0.5[Ω], and RWx_1＋RWx_2=0[Ω] (the ideal patterning condition), then
Output current value (ch4); IOUT4[A] = 0.1[V]÷(0.5[Ω]＋0.004[Ω]＋0[Ω]) = 0.198
Output current value (ch5); IOUT5[A] = 0.1[V]÷(0.5[Ω]＋0.022[Ω]＋0[Ω]) = 0.191
Else if there are VDACx=0.1[V], RRNFx= 0.5[Ω], and RWx_1＋RWx_2=0.05[Ω] (the more closely real patterning
condition; the value is different to the patterning), then
Output current value (ch4); IOUT4[A] = 0.1[V]÷(0.5[Ω]＋0.004[Ω]＋0.05[Ω]) = 0.181
Output current value (ch5); IOUT5[A] = 0.1[V]÷(0.5[Ω]＋0.022[Ω]＋0.05[Ω]) = 0.175

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)

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 400mA3% 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.

●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
BD6370GUL, BD6758MWV, BD6758KN
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.
