device against low energy spikes (see ISO7637
transient compatibility table). This device has two
channels in high side configuration; each channel
has an analog sense output on which the sensing
current is proportional (according to a known ratio)
to the corresponding load current. Built-in thermal
shut-down and outputs current limitation protect
the chip from over temperature and short circuit.
Device turns off in case of ground pin
disconnection.
