DIR OUT
The DIR OUT indicates the direction the motor is rotating, clock-
wise (CW) or counterclockwise (CCW).
BRUSH MOTOR OPERATION
The PWR-82520X can also be used as a brush motor controller
for current or voltage control in an H-Bridge configuration. The
PWR-82520X would be connected as shown in FIGURE 13. All
other connections are as shown in either FIGURE 11 or 12
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.
THERMAL OPERATION
It is recommended the PWR-82520X be mounted to a heat sink.
This heat sink shall have the capacity to dissipate heat generat-
ed by the hybrid at all levels of current output, up to the peak
limit, while maintaining the case temperature limit as per FIG-
URE 9.
RADIATION (PWR-82520R Series Only)
Total Dose: The hybrid shall operate, as specified in TABLE 2,
when subjected 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 shall be latch-up immune and still meet
the requirement of TABLE 2 for a LET level of 36 MeV/mg/cm2.
