DESCRIPTION

The MSA260 is a surface mount constructed PWM ampliﬁer

that provides a cost effective solution in many industrial applica-

tions. The MSA260 offers outstanding performance that rivals

many much more expensive hybrid components. The MSA260

is a complete PWM ampliﬁer including an oscillator, comparator,

error 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 mounted to a heatsink.

TYPICAL APPLICATION

TORQUE MOTOR CONTROL

With the addition of a few external components the MSA260

becomes a motor torque controller. In the MSA260 the source

terminal of each low side IGBT driver is brought out for current

sensing via RSA and RSB. A1 is a differential ampliﬁer that

ampliﬁes the difference in currents of the two half bridges. This

signal is fed into the internal error ampliﬁer that mixes the cur-

rent signal and the control signal. The result is an input signal

to the MSA260 that controls the torque on the motor.
