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 f our kinds of f unction f or select.In case of SELECT1, the bias of all circuit becomes OFF.

Theref ore, this mode is aVailable in order to reduce the power dissipation when the waiting mode.

In case of SELECT2, the bias of other than Loading circuit becomes OFF.

Theref ore, this mode is aVailable in order to reduce the power dissipation when the actiVe mode.

In case of SELECT3,it is possible to select the short braking to take the brake of Spindle motor.

Also,in case of SELECT4,it is possible to select PWM rev erse braking when in the same.

Loading channel

The loading channel is the circuit of BTL Voltage driv e.

This circuit has the ref erential input.

Output swing is determined with Vin X 8. Also,

it is possible f or this channel to use f or the slide motor ,

the f ocus coil and the tracking coil.

The input terminal is high impedance.

It is possible to do v ariable a gain by external resistor.

In case of one MCU port, if use three state port,

it is possible f or this channel to haVe the stop f unction.
