This board provides you an easy way to connect STMicroelectronics® VIPower® M0-7 technology into your existing system.
The board comes pre-assembled with VNQ7140AJ high-side driver. On board, a 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 VNQ7140AJ is a quad 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 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.
