Overview

EV-VN7004CH
Overview
The board comes pre-assembled with VN7004CH 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 VN7004CH is a single channel high-side driver manufactured using ST proprietary
VIPower technology and housed in the Octapak package. The device is designed to drive
12 V automotive grounded loads through a 3 V and 5 V CMOS-compatible interface,
providing protection and diagnostics.
The device integrates advanced protective functions such as load current limitation,
overload active management by power limitation and overtemperature shutdown.
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.

In case the user wishes to utilize the Current Sense / MultiSense function of the device, it is
necessary to plug a sense resistor in Rsense.
The package includes a through-hole resistor, to be mounted on TP1-TP2 - see Figure 4.
Different Rsense values can be adopted based on user preference.
Another option is soldering an SMD resistor on the dedicated PCB pad, as shown in
Figure 5.
