PRECAUTIONS FOR APPLICATION
(1) If the motor resistance is high (small output current: several
tens of mA at a light load) and Vcc is greater than Vcc' in
application examples 2) and 3), current may counter-flow from
the Vcc pin to the Vcc' pin.
The motor can work at a light load even when the Vcc' pin is
opened. For light-load applications, use the M54544L.
Through current of 2 to 4A flows from the power supply to GND
for 2 to 4us when switching a mode. Remember to connect a
capacitor of 10 to 100
µF between the output power supply and
the GND. If the motor has a large counter electromotive force
at a braking time, etc., the internal parasitic Di may malfunction.
If fly-back current of 1A or more flows, put a shottkey Di
between the output and the GND.
Remember that the IC has an about 10
µs delay in output
switching for high-speed applications such as PWM.
(2)As far as motor control and driver IC's are concerned, some
possibilities are considered for these IC's to cause such
unexpected cases as fire or smoke if they are used beyond its
ratings in datasheet or used, even transiently, under the
overload conditions. So your action will be highly appreciated
to fully look into the rating limits and the using conditions before
you use these IC's.
And if these IC's are to be used under the conditions out of our
specifications, please never fail to give us a contact as to under
what conditions they are used.
