Description
This board provides you an easy way to connect STMicroelectronics VIPower M0-7 technology into your existing
system.
The board comes pre-assembled with VN7E010AJ 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 VN7E010AJ is a single 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, 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 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.

Board connections
In case the user wishes to use the CurrentSense/MultiSense function of the device, it is necessary to plug a
sense resistor in RSENSE.
The package includes a through-hole resistor, to be mounted on TP1-TP2 (see Figure 4. Mounting through-hole
sense resistor).
Different RSENSE values can be adopted based on user preference.
Another option is soldering an SMD resistor on the dedicated PCB pad, as shown in Figure 5. Pads for soldering
SMD resistor.
