ADDITIONAL DOCUMENTATION
THERMAL ADDENDUM (REV 2.0)
INTRODUCTION
This thermal addendum is provided as a supplement to the MC33989 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 MC33989 is offered in a 28 pin SOICW, 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.
