Unit
Measured using standard circuits.
R
L
is the resistance of the motor coil connected between O1 and O2.
The rating varies depending on the device selected. Please refer to the series lineup table for details.
F output voltage is the difference voltage, with load capacitor C
L
connected between F and VSS pins, between 0.5V
DD
and the peak voltage.
