side connected to ground. A cti ve VCC pin voltage
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 ana log sense
output on which the sensing current is proportional
(according to a known rati o ) to the corr esponding
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.

Series resistor in INPUT line is also required to prevent
that, dur ing battery voltage transient, the current exceeds
the Absolute Maximum Rating.
Safest c onfigura tion for unused INPUT pin is to l eave it
unconnected, while unused SENSE pin has to be
connected to Ground pin.
LOAD DUMP PROTECTION
Dld is necessary (Voltage Transient Suppressor) if the
load dump peak voltage exceeds VCC max DC rating. The
same applies if the device will be subject to transients on
