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, SHORTBRAKE-MODE is superior to PWM-BRAKE-MODE to reducing the power dissipation and to av oid braking down of this IC. (By excessiVe rev erse torque current in braking a motor with PWM-BRAKE f rom 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 sy nchronizing 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-of f all output trangister of H bridge f or 3usec.
Output current setting at SLIDE
In this IC, since output tranjister is NPN-ty pe tranjister, motor coil current (Io) is larger than sensing resistance current about 10mA (TYP.) according to base current of output tranjister. Theref ore please design output current with consisting these base current.
