Therefore ,this mode is av ailable in order to reduce a temperature under acceleration.
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. 5volts. 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.

The current gain[Gio] is 20A/V (at sensing resistor : 0.5 ohm,and R1= ,R2=0ohm) in forward torque directions, and the dead zone is from 0mV to 80mV (at R1= ,R2=0ohm) The coil current gain under the reverse torque is the same with IN forward torque directions.And the limitation function gets on when the differential voltage of VM1(12V) RSP is 0.5Vat forward and 0.3V at reverse in case of SELECT6, SELECT7,SELECT8 the differential voltage of VM1 (12V) RSP is 0.3Vat forward.

Direct PWM operation
The spindle and the slide channel is controlled by the direct PWM control. Analog input voltage control the driving current which is in proportion to input voltage. This control is direct PWM control type of motor current chopper. Also,built-in the current limit circuit. This IC controls the motor current directly. direct PWM operation as follows; 1) The current which flows on a motor is detected, and current is supplied from a power supply until it reaches the predetermined instruction value to which the current is proportional to input voltage. 2) When current reaches an instruction value, an output transistor is changed and the period coil inertia energy to a career cycle is made to regeneration using an internal path. 3) After repeat 1) and 2). Therefore, the IC constantly surveillance and control the current value itself use sensor resistor. Moreover, these ICs built-in current limit circuit so that protect to large current. Thus, if input excessive control voltage, the current don't flow that settle limit current.

Recommendation of SHORT BRAKE MODE at Spindle DRIVE
This IC has two brake mode, PWM-BRAKE-MODE and SHORT-BRAKE-MODE. IN this IC recommendation, SHORT-BRAKE-MODE is superior to PWM-BRAKE-MODE to reducing the power dissipation and to avoid breaking down of this IC. (By excessive reverse torque current IN braking a Motor with PWM-BRAKE from high-speed-rotation with being excessive Back-EMF, this IC could be broken.)

FG function at Spindle DRIVE
The FG terminal outputs the square pulse signal synchronizing with the Hall inputs [Hu+,Hu-, Hv+, Hv-,Hw+,Hw-] timing.And, the FG terminal is open-collector output. (cf.FG timing chart on the previous page)
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 transistor of Hbridge for 3usec.
Output current setting at Slide
IN this IC, since output transistor is NPN-type transistor, Motor coil current (Io) is larger than sensing resistance current about 20mA (TYP.) according to base current of output transistor. Therefore please design output current with consisting these base current.

[The Notes on designing the layout of the board]
This IC has direct PWM controls for the Spindle channel and the Slide channel drive, therefore the circuits of the IC are influenced more easily by the PWM switching noise than those have linear controls. Please refer to the following notes on the occasion of designing the layout pattern of the board on which the IC is mounted.
note1
I t is necessary for some application in order to reduce the PWM noise that pass condensers are connected between power supply pins(VM23:4pin, VM1:22pin, 5VCC:39pin) and GND pin, even if the power supplies of the application already have pass condensers. The closer the connection points of the condensers are to the pins, the more effective it is to reduce the noise. Please refer to the values of the condensers on the page of [An example of the values of the external parts.] (The value of the condensers is only a reference value. It differs in each application because the bad influence of PWM noise relates to the layout pattern of the board.)
note2
The feedback point of the Spindle channel [the Slide channel] is the connected point to the VM1(22pin) [the VM23(4pin)] line from the RSP(15pin) [RSL(8pin)] pin through the sensing resistor RSP[RSL]. Therefore the closer the feedback point is to the power supply pin, the more stable the circuits are for the PWM noise. cf. [application circuit]
note3
The farther the large current output lines(especially PWM output lines of the Spindle CH. and the Slide CH.) which are indicated as wide lines in the Fig. [application circuit] are to the small signal input lines, the less the bad influence of the PWM noise comes to be without the cross-talk between a large current output line and a small input signal line.

note4
IN case the PWM switching noise influences the REF input, it is necessary for some application that a condenser is connected between REF pin(25pin) and GND pin. The closer the connection points of the condensers are to the pins, the more effective it is to reduce the noise. (This is the same as note1.) cf.[application circuit], [An example of the values of the external parts]
note5
The closer the GND side of the capacitor connected with OSC pin (30 pin) is to the GND pin(33pin), which is the nearest GND to the GND of the small signal circuit inside the IC, the less the bad influence of the PWM noise on the GND line comes to be. cf. [application circuit]
