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.
