APPLICATIONS
• LINEAR AND ROTARY MOTOR DRIVES
• YOKE/MAGNETIC FIELD DEFLECTION
• PROGRAMMABLE POWER SUPPLIES to ±68V
• TRANSDUCER/AUDIO TO 1000W
DESCRIPTION
brute force power and self protection against abnormal oper-
ating conditions. Its features start with a copper dip package
developed by Apex Precision Power to extend power capabilities
well beyond those attainable with the familiar TO-3 package.
The increased pin count of the new package provides addi-
tional control features, while the superior thermal conductivity
of copper allows substantially higher power ratings.
limiting internal power dissipation to a curve approximating
the safe operating area of the power transistors. The internal
current limit of 35A is supplemented with thermal sensing
which reduces the current limit as the substrate temperature
rises. Furthermore, a subcircuit monitors actual junction
temperatures and with a response time of less than ten mil-
liseconds reduces the current limit further to keep the junction
temperature at 175°C.
FET input stage providing superior DC accuracies both initially
and over the full temperature range.
