Overview

It comes pre-assembled with VN7040AS-E high-side driver. On board minimum set of

electrical components (as for device datasheet recommendation) is enabling the user to

directly connect the load, the power supply and the microcontroller without any additional

effort in external component design and connection.

The VN7040AS-E is a single channel high-side driver manufactured using ST proprietary

VIPower

automotive grounded loads through a 3 V and 5 V CMOS-compatible interface and to

provide protection and diagnostics.

The device integrates also advanced protective functions such as load current limitation,

overload active management by power limitation and overtemperature shutdown.

A dedicated high precision proportional load current sense is available, in addition to the

A sense enable pin allows OFF-state diagnosis to be disabled during the module low-

power mode as well as external sense resistor sharing among similar devices.
