Low Power Dissipation mode
Motor Lock mode
2-Phase Excitation mode
Note: 2-phase excitation has a large load change due to motor induced electromotive force. If a mode in
Low Power Dissipation mode turns off phases A and B, and also halts the charge pump.
Operation is the same as that when the STANDBY pin is set to Low.
Motor Lock mode turns phase B output only off with phase A off.
From reset, with IA = 0 and IB = 100%, the normal 4W1-2 phase operating current is output.
Use this mode when you want to hold (lock) the rotor at any desired value.

[%]
which the current attenuation capability (current control capability) is small is used, current increase
due to induced electromotive force may not be suppressed. In such a case, use a mode in which
the mixed decay ratio is large.
We recommend 37.5% Mixed Decay mode as the initial value (general condition).
