Two or more devices can easily be connected in
parallel to increase load current capability.
19) _{Overload is detected at the following condition: 1V (typ.) < VON < 3.5V (typ.) . See also page 11.}
20) _{Short Circuit is detected at the following condition: VON > 3.5V (typ.) . See also page 11.}
21) _{Low ohmic short to Vbb may reduce the output current IL and therefore also the sense current IIS.}
