The BD6370GUL is a motor driver that integrates 3
Full-ON or Constant-Voltage type H-bridges, 1
Constant-Voltage or Linear Constant-Current or
Full-ON type H-bridge and 1 Linear Constant-Current
type H-bridge. The device can drive one stepping
motor for auto focus, and DC motors for zoom and iris.
It is therefore possible to drive another stepping motor
for either zoom or iris, because it has the system to
drive 6-channel H-bridges exclusively.

Description of Blocks
1.
Power-Saving and Serial Reset
A power-saving function is included, which allows the system to save power when not driving the motor. The voltage
level on this pin should be set high so as to keep the operation mode. (See the Electrical Characteristics; p.7/32)
Cancel power-saving mode after turning on power supply V CC and VM, because PS pin combines with power-saving
function and serial reset function block. If PS pin is always short-circuited to the power supply VCC terminal, reset
function may not work, and it may cause the device to malfunction.
(See the Sequence of Serial Control Input; p.9/32)
2.
Motor Control Input (INPUT1, INPUT2, INPUT34, INPUT45)
Logic level controls the output logic of H-Bridge.
(See the Electrical Characteristics; p.7/32 and I/O Truth Table; p.19/32 to p.23/32)
INPUT34 pin corresponds to channel 3 or channel 4, and INPUT45 pin to channel 4 or channel 5 respectively. These
channels can be set via serial interface.
3.
H-Bridge
Because the respective output transistors consist of power CMOS which consumes a motor power supply VM, the
high and low-side ON-Resistance value is dependent upon VM voltage. Further, the application must be designed so
that the maximum H-bridge current for each channel is 400mA or below.
(See the Recommended Operating Conditions; p.6/32)
The 3 H-bridges (channel 1 to channel 3) can be driven as the exclusive 4-channel. As long as two stepping motors
don’t drive simultaneously, it is possible to drive them by channel 1 to channel 3.

4.
The D/A Converter Settings for Each Channel
The three H-Bridges (channel 1 to 3) can drive motors as Constant-Voltage or Full-ON mode. The H-Bridge of
channel 4 can drive it as Constant-Voltage or Constant-Current or Full-ON mode, while the H-Bridge of channel 5 is
always set for Constant-Current mode. In case of driving each H-bridge as Full-ON mode, serial data of each D/A
Converter (DAC12 and DAC3) for Constant-Voltage mode should be set all bits high. If channel 4 is set to
Constant-Voltage mode, serial data of D/A Converter (DACI4) for Constant-Current mode should be set all bits high.
In case of driving H-bridge as Constant-Current mode, serial data of D/A Converter (DACV4) for Constant-Voltage
mode should be set all bits high, while driving as Full-ON mode, serial data of both D/A Converters should be set all
bits high. In case of driving channel 4 as Constant-Voltage or Full-ON mode, it is not necessary to connect the
external resistor for output current detection at RNF4 pin. When driving as Constant-Current mode, design the
application in consideration of both internal metal impedance and external resistor for output current detection.
(a) Full-ON Mode (Channel 1 to Channel 4)
D/A Converter Setting Range
VDACx: 6’b111111 Fixed (x = 12, 3, V4, and I4)
(b) Constant-Voltage Mode (Channel 1 to Channel 4)
Formula for Output High Voltage:
VVOHx[V] = 8 x VDACx[V] (8 x VDACx ≤ VM[V], x = 12, 3, and V4)
VVOHx[V] = VM[V] (8 x VDACx > VM[V], x = 12, 3, and V4)
D/A Converter Setting Range
8 x VDACx: 6’b010100 to 111111 (x = 12, 3, and V4)
(In case of setting channel 4, set VDACI4: 6’b111111, in addition to the above condition)
(c) Constant-Current Mode (Channel 4 & Channel 5)
Formula for Output Current:
IOUTx[A] = VDACx[V] / (RMETALx[Ω] + RNFx[Ω]) (x = I4 and 5)
RMETALx; the internal metal impedance
(Channel 4; RMETALI4[Ω] = 0.004(Typ))
(Channel 5; RMETAL5[Ω] = 0.022(Typ))
RNFx; the resistor value for output current detection at RNFx pin
D/A Converter Setting Range
VDACx: 6’b001010 to 111111 (x = I4 and 5)
(In case of setting channel 4, set VDACV4: 6’b111111, in addition to the above condition)

Timing chart
Serial Input (STROBE, SCLK, and SDATA)
The BD6370GUL provides the D/A converter and 3-line serial interface for setting output modes.
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 internal 12-bit memory simultaneously with STROBE rising edge, according to
the addresses stored in Bit[E], Bit[D], and Bit[C]. The input first serial data is Bit[E] and the last is Bit[0].
In case of the exclusive drive mode (MODE13=1 and/or MODE23=1), each serial bit of DAC12 and DAC3 should be
input the same data.
Cancel power-saving mode after turning on power supply V CC and VM. All serial data will be reset to 0 when the PS
pin voltage changes to Low-level, because PS pin combines with power-saving function and serial data clear
function block. These data will be also reset to 0 when the UVLO or TSD circuit operates.

Operational Notes
1.
Reverse Connection of Power Supply
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power
supply pins.
2.
Power Supply Lines
Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the
digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog
block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and
aging on the capacitance value when using electrolytic capacitors.
3.
Ground Voltage
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.
4.
Ground Wiring Pattern
When using both small-signal(GND) and large-current ground(PGND) traces, the two ground traces should be routed
separately but connected to a single ground at the reference point of the application board to avoid fluctuations in the
small-signal ground caused by large currents. Also ensure that the ground traces of external components do not
cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line
impedance.
5.
Thermal Consideration
Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in
deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, increase the board size
and copper area to prevent exceeding the Pd rating.
6.
Recommended Operating Conditions
These conditions represent a range within which the expected characteristics of the IC can be approximately
obtained. The electrical characteristics are guaranteed under the conditions of each parameter.
7.
Inrush Current
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may
flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power
supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring,
and routing of connections.
8.
Operation Under Strong Electromagnetic Field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
9.
Testing on Application Boards
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply
should always be turned off completely before connecting or removing it from the test setup during the inspection
process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during
transport and storage.
10. Inter-pin Short and Mounting Errors
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in
damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.
Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment)
and unintentional solder bridge deposited in between pins during assembly to name a few.
11. Unused Input Pins
Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and
extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small
charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and
cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the
power supply or ground line.

Operational Notes – continued
12. Regarding the Input Pin of the IC
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them
isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a
parasitic diode or transistor. For example (refer to figure below):
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, operational faults, or physical damage. Therefore, conditions that cause these diodes to
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should
be avoided.

Example of monolithic IC structure
13. Ceramic Capacitor
When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with
temperature and the decrease in nominal capacitance due to DC bias and others.
14. Area of Safe Operation (ASO)
Operate the IC such that the output voltage, output current, and power dissipation are all within the Area of Safe
Operation (ASO).
15. Thermal Shutdown Circuit(TSD)
This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always
be within the IC’s power dissipation rating. If however the rating is exceeded for a continued period, the junction
temperature (Tj) will rise which will activate the TSD circuit that will turn OFF all output pins. When the Tj falls below
the TSD threshold, the circuits are automatically restored to normal operation.
Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no
circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from
heat damage.
16. Disturbance light
In a device where a portion of silicon is exposed to light such as in a WL-CSP, IC characteristics may be affected due
to photoelectric effect. For this reason, it is recommended to come up with countermeasures that will prevent the chip
from being exposed to light.
