DESCRIPTION
structed component that provides a cost effective solution in
many industrial applications. The MP230 offers outstanding
performance that rivals many much more expensive hybrid
components yet has a footprint of only 4.7 sq in. The MP230
has many optional features such as four-wire current limit sens-
ing, a shutdown control and external compensation. In addition,
the class A/B output stage biasing can be turned off for lower
quiescent current with class C operation in applications where
crossover distortion is less important such as when driving motors,
for example. A boost voltage feature biases the output stage for
close linear swings to the supply rail for extra efficient operation.
The MP230 is built on a thermally conductive but electrically
insulating substrate that can be mounted to a heat sink.

TYPICAL APPLICATION
MOTOR POSITION CONTROL
SOA performance compared to bipolar output stages where
secondary breakdown is a concern. The extended SOA is
ideal in motor drive applications where the back EMF of the
motor may impose simultaneously both high voltage and high
current across the output stage transistors. In the figure above
a mechanical to electrical feedback position converter allows
the MP230 to drive the motor in either direction to a set point
determined by the DAC voltage.
