Notes 1.
This IC has a circuit that prevents current from flowing into the V
M
pin when V
DD
= 0 V.
2.
The accuracy of the output current for ch1 to ch4 depends upon the motor that is actually used, but the
current fluctuations of the IC are determined by reference voltage and current detection ratios. Assume that
the total of the reference voltage V
REF
and current sense circuit errors are equal to ±10%.
