Short to V
A short circuit between V

during the on-state depending on the nature of the short circuit.
Off-state open-load with external circuitry
Detection of an open-load in off mode requires an external pull-up resistor R
the output to a positive supply voltage V
It is preferable V
overall standby current consumption to increase in normal conditions, i.e. when load is
connected.
An external pull down resistor R
avoid misdetection in case of floating outputs in off-state (see
diagnostic).

For proper open-load detection in off-state, the external pull-up resistor must be selected
