THERMAL ADDENDUM (REV 2.0)

Introduction

This thermal addendum is provided as a supplement to the MC33186 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 datasheet.

Package and Thermal Considerations

The MC33186 is offered in a 20 pin HSOP exposed pad, single die package.

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.
