This IC has two MUTE terminal (MU1 and MU2).
It is possible to control ON / OFF of each channel by external logic inputs.
It has four kinds of function for select.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,it is possible to select the PWM reverse braking to take the brake of Spindle motor.
Also,in case of SELECT4,it is possible to select the short braking when in the same.
In case of SELECT3,it is possible to do OFF the slide channel.
Regard with making OFF the loading channel in case of SELECT2,SELECT3 and SELECT4,please refer to
[Loading channel].
Loading channel
The loading channel is the circuit of BTL voltage drive. This circuit has the referential input. Output swing is determined
with DVin X 8. Also,it is possible for this channel to use for the slide motor , the focus coil and the tracking coil.
The input terminal is high impedance. It is possible to do variable a gain by external resistor.
The output becomes high impedance in case of both input voltage becomes under 0.5 volts. It is possible for the input
terminal to operate from 0 volts.The following table and diagram show an application in case of two MCU port and one
MCU port for the loading motor.In case of one MCU port, if use three state port, it is possible for this channel to have
the stop function.
