36V Stepping Motor Driver
BD63610AEFV
●General Description
BD63610AEFV is a bipolar low-consumption driver that
driven by PWM current. Rated power supply voltage of
the device is 36 V, and rated output current is 0.8A.
CLK-IN driving mode is adopted for input interface, and
excitation mode is corresponding to FULL STEP mode,
HALF STEP mode. In addition, the power supply may
be driven by one single system, which simplifies the
design.
● Features
■ Rated output current（DC）0.8A
■ Low ON resistance DMOS output
■ CLK-IN drive mode
■ PWM constant current (other oscillation)
Built-in spike noise cancel function (external noise
filter is unnecessary)
■ Full, half step functionality
■ Freely timing excitation mode switch
■ Normal rotation & reverse rotation switching
function
■ Power save function
■ Built-in logic input pull-down resistor
■ Power-on reset function
■ Thermal shutdown circuit (TSD)
■ Over-current protection circuit（OCP）
■ Under voltage lock out circuit (UVLO)
■ Over voltage lock out circuit (OVLO)
■ Ghost Supply Prevention (protects against
malfunction when power supply is disconnected)
■ Microminiature, ultra-thin and high heat-radiation
(exposed metal type) package
● Application
■ PPC, multi-function printer, laser beam printer, and
ink-jet printer
■ Monitoring camera and WEB camera
■ Sewing machine
■ Photo printer, FAX, scanner and mini printer
■ Toy and robot
● Major Characteristics
■ Range of power supply voltage
19～28 [V]
■ Rated output current
0.8 [A]
■ Rated output current (peak)
1.0 [A]
■ Range of operating temperature

●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.
○MODE／Motor Excitation Mode Setting Terminal
Set the motor excitation mode
MODE0
Excitation Mode
L FULL STEP
H HALF STEP
Please refer to the P.12, 13 for the timing chart & motor torque vector of various excitation modes.
Unrelated to CLK, change in setting is forcibly reflected (refer to P.15).
○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.14)
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.15).
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, 13).
