With the addition of a few exter-
nal components the MSA260 be-
comes a motor torque controller.
In the MSA260 the source termi-
nal of each low side IGBT driver
is brought out for current sensing
via R
A and R
B. A1 is a differen-
S
S
tial amplifier that amplifies the dif-
ference in currents of the two half
bridges. This signal is fed into the
internal error amplifier that mixes
the current signal and the control
signal. The result is an input sig-
nal to the MSA260 that controls
the torque on the motor.
