ADDITIONAL DOCUMENTATION
THERMAL ADDENDUM (REV 1.0)
Introduction
This thermal addendum ia provided as a supplement to the MM908E626
technical data sheet. 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.
Package and Thermal Considerations
This MM908E626 is a dual die package. There are two heat sources in the
package independently heating with P
1
and P
2
. This results in two junction
temperatures, T
J1
and T
J2
, and a thermal resistance matrix with R
θ
JA
mn
.
For
m
,
n
= 1, R
θ
JA11
is the thermal resistance from Junction 1 to the reference
temperature while only heat source 1 is heating with P
1
.
For
m
= 1,
n
= 2, R
θ
JA12
is the thermal resistance from Junction 1 to the
reference temperature while heat source 2 is heating with P
2
. This applies to
R
θ
J21
and R
θ
J22
, respectively.
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.
