clamp protects the 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.
