THERMAL OPERATION
It is recommended that the PWR-82520R be mounted to a heat
sink. This heat sink shall have the capacity to dissipate heat gen-
erated by the hybrid at all levels of current output, up to the peak
limit, while maintaining the case temperature limit as per
FIGURE 11.
RADIATION
TOTAL DOSE
The hybrid shall operate, as specified in TABLE 2, when subject-
ed to a total dose radiation environment of 100KRad (Si) at a
dose rate of 0.5 Rad/sec.
SINGLE EVENT UPSET
The hybrid shall be Single Event Upset (SEU) immune and still
meet the requirements of TABLE 2 for a Linear Energy Transfer
(LET) level of 36 MeV/mg/cm2.
LATCH-UP
The hybrid is latch-up immune and meets the requirement of
TABLE 2 for a LET (Linear Energy Threshold) level of
36 MeV/mg/cm2.

NOTE:
100KRad (Si) total dose of radiation is usually two to
three times the operational level of commercial and military satel-
lites. This is a large cost saving for the end users since Lot
Acceptance Tests (LAT) are usually not required.
BRUSH MOTOR OPERATION
The PWR-82520R can also be used as a brush motor controller
for current or voltage control in an H-Bridge configuration. The
PWR-82520R would be connected as shown in FIGURE 10.
All other connections are as shown in either FIGURES 6 or 7
depending on voltage or current mode operation. The Hall inputs
are wired per TABLE 4. A positive input command will result in
positive current to the motor out of Phase A.
OPTIONAL FEATURES
EXTERNAL SENSING RESISTOR
The external sensing point available for the end users to install
an external resistor (non-inductive). The resistance of the resis-
tor is scaled to the applicable current range. Please contact fac-
tory for this option.
