Figure 33. Current sense and diagnostic
3.3.1
Short to VCC and off-state open-load detection
Short to VCC
A short-circuit between VCC and output is indicated by the relevant current sense pin set to
VSENSEH during the device OFF-state. Small or no current is delivered by the current sense
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 RPU connecting
the output to a positive supply voltage VPU.
It is preferable VPU to be switched off during the module standby mode in order to avoid the
overall standby current consumption to increase in normal conditions, i.e. when load is
connected.
An external pull-down resistor RPD connected between output and GND is mandatory to
avoid misdetection in case of floating outputs in off-state (see Figure 33: Current sense and
RPD must be selected in order to ensure VOUT < VOLmin unless pulled-up by the external
