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) to 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.
