STMicroelectronics VNQ9080AJ
VNQ9080AJ - Quad channel high-side driver with Current Sense analog feedback for automotive applications
The device is a quad channel high-side driver manufactured using ST proprietary VIPower M0-9 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 diagnostic functions including high precision proportional load current 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.

EV-VNQ9080AJ - VNQ9080AJ evaluation board
The EV-VNQ9080AJ board provides an easy way to connect VNQ9080AJ into existing system.
The EV-VNQ9080AJ comes pre-assembled with VNQ9080AJ 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.
