This IC's package is POWER-SSOP, so improving the board on which the IC is mounted enables a large power dissipation without a heat sink. For example, using an 1 layer glass epoxy resin board, the IC's power dissipation is 2.6W at least. And it comes to 3.6W by using an improved 2 layer board.

Brake select Drive channel Focus Tracking Spindle Opamp (SPINThis 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.

Forward Torque
The relationship between the differential voltage between SPIN and REF and the torque is shown in right Figure. The voltage gain[Gvo] is 1.0 [V/V]. The current gain[Gio] is 2.0A/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) to RSP is 0.5V at forward and 0.3V at reverse. Therefore current-gain-control and current-limit of this IC is determined with sensing resister value, and more detail control can be determined with setting a gain-resister outer this IC as below.

The relationship between the differential voltage between SLIN and REF and the torque is shown in right Figure. The voltage gain[Gvo] is 1.0 [V/V]. The current gain is 2.0A/V (at sensing resistor : 0.5 ohm and R1=R2) in forward torque directions, and the dead zone is from 0mV to 60mV (at R1=R2=16kohm). 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 VM23(12V) to RSL is 0.5V. Therefore current-gain-control and current-limit of this IC is determined with sensing resister value.In the input part,built-in an inverted amplifier.

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, SHORTBRAKE-MODE is superior to PWM-BRAKE-MODE to reducing the power dissipation and to avoid braking 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 [Hv+, Hv-] timing. 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. Therefore please design output current with consisting these base current.
