Stepping Motor Driver series
Micro step 36V
Stepping Motor Drivers
BD63510EFV
●General Description
BD63510EFV series are stepping motor drivers of 1/16
micro step(sixteenth step) drive. As for its basic
function, it is a low power consumption bipolar PWM
constant current-drive driver with power supply rated
voltage of 36V and rated output current (DC) of 1.0A.
The input interface is CLK-IN type.
There are step modes of Full step & Half step, Quarter
step, Sixteenth step mode by internal DAC (D-A
converter), and for current decay mode, the ratio of
FAST DECAY & SLOW DECAY can be freely set, so the
optimum control conditions for every motor can be
realized. In addition, being able to drive with one system
of power supply makes contribution to the set design’s
getting easy.

●Function explanation
○CLK／Clock input terminal for advancing the electrical angle
CLK is reflected at rising edge. The Electrical angle advances by one for each CLK input.
Motor’s misstep will occur if noise is picked up at the CLK terminal, so please design the pattern in such a way that there is
no noise plunging.
○MODE0,MODE1/Motor excitation mode setting terminal
Set the step mode.
MODE0 MODE1
Step mode
LL
Full step
HL
Half step
LH
Quarter step
HH
1/16 step
Unrelated to CLK, change in setting is forcibly reflected (refer to P.14).
○CW_CCW Terminal／Motor rotating direction setting
Set the motor’s rotating direction. Change in setting is reflected at the CLK rising edge immediately after the change in
setting (refer to P.13)
CW_CCW
Rotating direction
L Clockwise (CH2’s current is outputted with a phase lag of 90°in regard to CH1’s current)
H
Counter Clockwise(CH2’s current is outputted with a phase lead of 90°in regard to CH1’s
current)
○ENABLE Terminal／Output enable terminal
Turn off forcibly all the output transistors (motor output is open).
When ENABLE=L, input to CLK is blocked, and phase advance operation of internal translator circuit is stopped.
However, during excitation modes (MODE0,MODE1) switch within the interval of ENABLE=L, as ENABLE=L→H is reset,
the new mode upon switch will be applied for excitation (See P.14).
ENABLE
Motor Output
L OPEN (electrical angle maintained)
H ACTIVE
○PS／Power save terminal
PS can make circuit standby state and make motor output OPEN. In standby state, translator circuit is reset (initialized) and
electrical angle is initialized.
Please be careful because there is a delay of 40μs(max.) before it is returned from standby state to normal state and the
motor output becomes ACTIVE (refer to P.11).
PS Status
L Standby state(RESET)
H ACTIVE
The electrical angle (initial electrical angle) of each excitation mode immediately after RESET is as follows
(refer to P.12).
Step mode
Initial electrical angle
Full step
45°
Half step
45°
Quarter step
45°
1/16 step

○TEST0,TEST1/ Terminal for testing
This is the terminal used at the time of shipping test. Please connect to GND. Please be careful because there is a
possibility of malfunction if GND unconnected.

●Translator circuit
This series builds in translator circuit and can drive stepping motor in CLK-IN mode.
The operation of the translator circuit in CLK-IN drive mode is described as below.
○Reset operation
The translator circuit is initialized by power ON Reset function and PS terminal.
・Initializing operation when power supply is turned on
①If power supply is turned on at PS=L (Please use this sequence as a general rule)
When power supply is turned on, the power ON reset function operates in IC and initialized, but as long as it is PS=L,
the motor output is the OPEN state. After power supply is turned on, because of the changing of PS=L⇒H, the motor
output becomes the ACTIVE state, and the excitation is started at the initial electrical angle.
But at the time of PS=L⇒H, it returns from the standby state to the normal state and there is a delay of 40μs(max.)
until the motor output has become the ACTIVE state.

Motor output ON
②If power supply is turned on at PS=H
When power supply is turned on, the power ON function in IC operates, and initialized before the motor output
becomes the ACTIVE state, and the excitation is started at the initial electrical angle.
・Initializing operation during motor operating
Please input the reset signal to PS terminal when the translator circuit is initialized during motor operating. (Refer to
P.14) But at the time of PS=L⇒H, it returns from the standby state to the normal state and there is a delay of 40μs
(max.) until the motor output has become the ACTIVE state, so please be careful.
○Control input timing
Please input as shown below because the translator circuit operates at the rising edge of CLK signal. If you disobey this
timing and input, then there is the possibility that the translator circuit does not operate as expected. In addition, at the time
of PS=L⇒H, it returns from the standby state to the normal state and there is a delay of 40μs (max.) until the motor output
has become the ACTIVE state, so within this delay interval there is no phase advance operation even if CLK is inputted.
