ADDITIONAL DOCUMENTATION
THERMAL ADDENDUM (REV 2.0)
Introduction
This thermal addendum is provided as a supplement to the MC33742
technical datasheet. The addendum provides thermal performance
information that may be critical in the design and development of system
applications. All electrical, application, and packaging information is
provided in the data sheet.
Packaging and Thermal Considerations
The MC33742 is offered in a 28 pin SOICW exposed pad, single die
package. There is a single heat source (P), a single junction temperature
(T
J
), and thermal resistance (R
θ
JA
).
The stated values are solely for a thermal performance comparison of
one package to another in a standardized environment. This methodology
is not meant to and will not predict the performance of a package in an
application-specific environment. Stated values were obtained by
measurement and simulation according to the standards listed below.
