The inputs of the device can withstand reverse voltages up
to 20V. Current flow into the device will be limited to less
than 1mA (typically less than 100 A) and no negative
voltage will appear at the output. The device will protect
both itself and the load. This provides protection against
batteries which can be plugged in backwards. Internal
protection circuitry isolates the inputs to prevent current
flow from one input to the other. Even with one input
supplying all bias currents and the other being plugged in
backwards (a maximum total differential of 40V), current

flow from one input to another will be limited to less than
1mA. Output voltage will be unaffected. In the case of
reverse inputs, no reverse voltages will appear at the load.
Pulling the SS pin low will cause all load currents to come
from the secondary input. If the secondary input is not
present, the output will be turned off. If the part is put into
current limit with the SS pin pulled low, current limit will
be drawn from the secondary input until it is discharged,
at which point the current limit will drop to zero.
