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.
