Overview
The board comes pre-assembled with VND7050AJ-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 VND7050AJ-E is a double channel high-side driver manufactured using ST proprietary
VIPower^® technology and housed in PowerSSO-16 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.
