Description

The VN610SP 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
against low energy spikes (see ISO7637 transient
compatibility table). This device integrates an
analog current sense which delivers a current
proportional to the load current (according to a
known ratio).

Active current limitation combined with thermal
shutdown and automatic restart protect the device
against over-load. Device automatically turns off
in case of ground pin disconnection.

2.1 Absolute maximum ratings

Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality document.

Note: To ensure long term reliability under heavy over-load or short circuit conditions, protection

and related diagnostic signals must be used together with a proper software strategy. If the
