It is possible to control ON / OFF of each channel by external logic inputs. It has four kinds of function for channel 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,the bias of the loading, the slide and the regulator amplifier circuit becomes ON. In case of SELECT3,it is possible to make OFF the loading channel only. In case of SELECT4,the bias of all channel becomes ON. 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 Vin 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 0.7 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.

And, the FG terminal is open-collector output. Phase delay circuit at SLIDE Phase delay circuit is built in the IC to detect an output spike current, when the motor current direction is switching. In switching the motor current direction, Phase delay circuit switch-off all output trangister of H-bridge for 3sec. Output current setting at SLIDE In this IC, since output tranjister is NPN-type tranjister, motor coil current (Io) is larger than sensing resistance current about 20mA (TYP.) according to base current of output tranjister.
