Stepping Motor Driver series
Micro step 36V
Stepping Motor Drivers
BD63520AEFV
●General Description
BD63520AEFV 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 2.0A.
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.

○CR/Connection terminal of CR for setting chopping frequency
This is the terminal to set the chopping frequency of output. Please connect the external C(470p~1500pF) and R(10k~
200kΩ) between this terminal and GND. Please refer to P9. Please interconnect from external components to GND in such
a way that the interconnection does not have impedance in common with other GND patterns. In addition, please carry out
the pattern design in such ways as keeps such steep pulses as square wave etc. away and that there is no noise plunging.
Please mount the two components of C and R if being used by PWM constant current control because normal PWM
constant current control becomes impossible if CR terminal is open or it is biased externally.
○MTH/ Current decay mode-setting terminal
This is the terminal to set the current decay mode. Current decay mode can be optionally set according to input voltage.
MTH terminal input voltage [V]
Current decay mode
0~0.3
SLOW DECAY
0.4~1.0
MIX DECAY
1.5~3.5
FAST DECAY
Please connect to GND if using at SLOW DECAY mode.
Please avoid using with MTH terminal open because if MTH terminal is open, the input is unsettled, and then there is the
danger that PWM operation becomes unstable. Besides, please take into consideration the outflow current (max.2µA) if
inputted by resistance division when selecting the resistance value.
○NC terminal
This terminal is unconnected electrically with IC internal circuit.
○IC back metal
For HTSSOP-B28 package, the heat-radiating metal is mounted on IC’s back side, and on the metal the heat-radiating
treatment is performed when in use, which becomes the precondition to use, so please secure sufficiently the
heat-radiating area by surely connecting by solder with the GND plane on the board and getting as wide GND pattern as
possible. Please be careful because the allowable loss as shown in P.20 cannot be secured if not connected by solder.
Moreover, the back side metal is shorted with IC chip’s back side and becomes the GND potential, so there is the danger
of malfunction and destruction if shorted with potentials other than GND, therefore please absolutely do not design
patterns other than GND through the IC’s back side.
