Figure 5: Plot of PI2001 response time to reverse current detection

Test Setup:
DUT:
PI5101-EVAL1
Vin1 = 3.3V
Vin2 = 3.3V
Output Load = 20A

Test:
Both input sources are
turned on and sharing the
load current, then applied a
short with fast turn on 1mΩ
MOSFET between Vin1 and
Gnd.

Test purpose:
To show the PI2001 response
to a fault condition, where
the output of the input
source is shorted or tried to
source current from the load
(Vout)
