Overview
EV-VN7040AS
1
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^® technology and housed in SO-8 package. The device is designed to drive 12 V
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
detection of overload and short circuit to ground, short to V_CC and OFF-state open-load.
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.
