Description
EV-VND7020AJ
The board provides you an easy way to connect ST VIPower^® M0-7 technology into your
existing system.
The EV-VND7020AJ evaluation board comes pre-assembled with a VND7020AJ high-side
driver.
On board minimum set of electrical components (as for device datasheet recommendation)
enables the user to directly connect the load, the power supply and the microcontroller
without any additional effort in external component design and connection.
The VND7020AJ is a double channel high-side driver manufactured using ST proprietary
VIPower M0-7 technology and housed in PowerSSO-16 package. It 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 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.
