This board provides you an easy way to connect STMicroelectronics® VIPower® M0-7 technology into your existing system.
It comes pre-assembled with VN7140AS 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 VN7140AS is a single channel high-side driver manufactured using ST proprietary VIPower technology and housed in SO-8 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 also advanced protective functions such as load current limitation, overload active management by power limitation and overtemperature shutdown.
A dedicated high precision proportional load current sense is available, 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.
