Counter-electromotive force
TA8409S/SG, F/FG
When the motor reverses or stops, counter-electromotive force in the motor may influence the current to flow
to the power source. If the power source lacks sink capability, the IC power and output pins may exceed the
rating. The counter-electromotive force of the motor varies depending on the conditions of use and the features
of the motor.
Therefore ensure that there is no damage to the IC or problem in operation, and no error in or damage to
peripheral circuits resulting from counter-electromotive force.
