General Description
The MSA260 is a surface mount constructed PWM
amplifier that provides a cost effective solution in many
industrial applications. The MSA260 offers outstand-
ing performance that rivals many much more expen-
sive hybrid components. The MSA260 is a complete
PWM amplifier including an oscillator, comparator, er-
ror amplifier, current limit comparators, 5V reference,
a smart controller and a full bridge IGBT output circuit.
The switching frequency is user programmable up to
50 kHz. The MSA260 is built on a thermally conductive
but electrically insulating substrate that can be mount-
ed to a heatsink.

Typical Application
TORQUE MOTOR CONTROL
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 RSA and RSB. A1 is a differen-
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.
