EV-VNQ7040AY:VNQ7040AY Evaluation Board
This board provides you an easy way to connect STMicroelectronics® VIPower® M0-7
technology into your existing system.The board comes pre-assembled with VNQ7040AY high-side driver. On
board, a 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 VNQ7040AY is a quad channel high-side driver
manufactured using ST proprietary VIPower technology and housed in PowerSSO-36 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 advanced protective functions such as load
current limitation, overload active management by power limitation and overtemperature shutdown with
configurable latch-off. A FaultRST pin unlatches the output in case of fault or disables the latch-off
functionality. A dedicated multifunction multiplexed analog output pin delivers sophisticated diagnostic
functions including high precision proportional load current sense, supply voltage feedback and chip
temperature sense, 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.
