Note 3. This TSD function start temperature doesn't show the guaranteed max. temperature of the devices.
The guranteed max. temperature is Tj max. which is shown in "9. ABSOLUTE MAXIMUM RATING". The TSD function is a thermal protection in case
the temperature of the devices goes up above Tjmax because of wrong use.
And these TSD temperature are the target temperatures for circuit design, not the guranteed temperatures.
(The TSD function of all the devices is not checked by a test in high temperature.)

This IC has MUTE terminal (MU1).
It is possible to control ON / OFF of the channel by external logic
inputs.
In case of SELECT1, the bias of all circuit becomes OFF.
Therefore, this mode is available in order to reduce the power
dissipation when the waiting mode.
In case of SELECT2,the bias of all channel becomes ON.

This IC has BRS terminal (BRS).
It is possible for a braking timiming of Spindle drive to select which the
short brake or the reverse brake by BRS.
It shuould select the short brake in case of high speed system and
please change to the reverse brake when the rotation speed becomes
enough low. It is available when the SPIN voltage is low than the
reference voltage.
