2-PHASE STEPPER MOTOR DRIVER
M54646AP
MITSUBISHI <CONTROL / DRIVER IC>
.
CAUTION
(1) Be sure to short-circuit V
CC1
and V
CC2
before use.
(2) When IC total output current changes greatly, e.g. when output
current flows intermittently due to thermal protection operation,
supply voltage may fluctuate. Provide power supply and wiring
such that even in such a case amperage will not exceed
absolute maximum rating.
(3) Excessive power voltage fluctuations may cause unstable IC
operation. To regulate such fluctuations, connect capacitor
between terminals V
CC
and GND as close to IC terminal as
possible. (Refer to application example.)
(4) Thermal protection function
Thermal protection characteristics may differ depending on
wiring layout. Be sure to test IC on circuit board before use.
After circuit board is replaced, test IC again.
Circuit boards on which this IC mounted are designed such
that impedance between power supply and output terminal will
be kept low; therefore, IC output terminal may be short-
circuited internally if excessive surge voltage is applied
accidentally from outside. To prevent circuit board from
burning in such a case, take safety measures such as
installation of a fuse.
(5) Flywheel diode
This IC has built in flywheel diode to provide a return current
route to motor. To prevent overheating and malfunction in
operational areas where great current and voltage are applied,
install a Schottky diode externally. For details, refer to “Area of
Safe Operation” and “Application Example.”
