on CH2 and then enable the load. Turn on the VIN2 power supply
and verify that input/output current is limited as per the setting in
. Verify the device is in
latched-off mode and that the FLTb2 RED LED (D7) turns ON as shown in
. The level of the
current pulse should match with the load current limit (based on the respective jumper setting) as
shown in
