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)
