STEPPER MOTOR DRIVER
M54640P
MITSUBISHI <CONTROL / DRIVER IC>
APPLICATION EXAMPLE
PRECAUTIONS FOR USE
(1) When the whole output current changes by a large margin (for
example, when overheat protection operation causes intermittent
flow of output current), the supply voltage may undergo a
change. Therefore, selection and wiring of power supply should
be conducted cautiously to avoid such a situation that the supply
voltage exceeds the absolute maximum ratings.
(2) When the supply voltage changes by a large margin, the
operation of this IC may become unstable. In this case, the
change of supply voltage can be controlled by connecting a
capacitor at the point near to IC pin between Vcc pin and GND
pin. (See above application example.)
(3) Thermal shutdown function
The state of thermal shutdown operation may differ according to
the way of wiring within a board. Therefore, sufficient board
evaluation should be conducted before use. When the board is
changed, operation on the replacing board should be evaluated.
The circuit board on which this IC is mounted is designed to
realize low impedance between power supply and output pin.
Therefore, it is desirable to take a safe measure such as fixing a
fuse to avoid such a situation that the board is damaged by a fire
when output pin is internally short-circuited by excessively
applied surge voltage by accident.
