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)~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)~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.

q FG function duty 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)
q FG function duty at spindle drive
FG function DUTY is shown in a below equation at rihgt Figure.
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 breaking 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.)

Note 5 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]
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 ocasion of designing the layout pattern of the board on which the IC is mounted. The bad influence of the PWM noise differs in each board, therefore please consider the following notes as the reference materials for designing the board. Note 1 It 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, VM4:38 pin, 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 condensors 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.) Note 2 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] Note 3 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. Note 4 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]
