Test Setup:
DUT: PI2126-EVAL1
Vin1+ = 12V
Vin2+ = 12V
Output Load = 12A
Test:
Both input sources are turned
on and sharing the load
current, then applied a short
between Vin1+ and Gnd for
1ms.
Test purpose:
To show the PI2126 response
to a fault condition, where the
output of the input source is
shorted or tried to source
current from the load (Vout).
