It shuould select the short brake in case of high speed system and please change to the reverse brake when the rotation speed becomes enough low. It is available when the SPIN voltage is low than the reference voltage.]

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. In case of one MCU port, if use three state port, it is possible for this channel to have the stop function.

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 2.0[A/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 0.5V. 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.

q 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 switchoff all output trangister of H-bridge for 3sec.
Note : This PWM carrier frequency is TYP value.
q Recommendation of short brake mode at spindle drive
This IC has two brake mode, PWM-BRAKE-MODE and SHORTBRAKE-MODE. In this IC recommendation, SHORT-BRAKEMODE 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 BackEMF, this IC could be broken.)
q 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 10mA (TYP.) according to base current of output tranjister. Therefore please design output current with consisting these base current.
