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.
