It is possible to control ON / OFF of each channel and to select current limit under acceleration by external logic inputs. It has six 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,the bias of other than Loading circuit becomes OFF. Therefore,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 tak e the brake of Spindle motor. in case of SELECT4,it is possible to select PWM reverse braking when in the same. In case of SELECT5,it is possible to select the 100%current limit under acceleration. Also,in case of SELECT6,it is possible to select the 56%current limit under acceleration. Therefore,this mode is available 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. 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 2.0[ A/V] (at sensing resistor :0.5Ω,and R1=∞, R2=0 Ω)in forward torque directions,and the dead zone is from 0mV to 80mV (at R1=∞, R2=0 Ω) 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 0.28V at reverse. In case of SELECT6 the differentialvoltage of VM1(12V)~RSP is 0.28V at forward.Therefore,this mode is available in order to reduce a temperature under acceleration.

In this IC recommendation, SHORT-BRAKE-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 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 transistor of H-bridge for 3 µsec. 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 10mA (TYP.)according to base current of output transistor. Therefore please design output current with consisting these base current.
