Overview
EV-VND7004AY
The board comes pre-assembled with VND7004AY 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 VND7004AY is a double channel high-side driver manufactured using ST proprietary
VIPower technology and housed in PowerSSO-36 packages. 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 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 VCC 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.
