PI2127

MOSFET

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).
