DESCRIPTION
The VND600 is a monolithic device made using
STMicroelectronics VIPower M0-3 technology. It
is intended for driving resistive or inductive loads
with one side connected to ground. Active V_CC 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
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.
