Thermal Imaging:
MOSFET
PI2127
Test Setup:
DUT: PI2127-EVAL1
Vin1+ = 48V
Vin2+ = 48V
Output Load = 5A
Test:
Both input sources are turned
on and sharing the load
current, then applied a short
with a screw driver between
Vin1+ and Vin1-.
Test purpose:
To show the PI2127 response
to a fault condition, where the
output of the input source is
shorted or tried to source
current from the load (Vout).
