STMicroelectronics VND70/VNQ70/VN9D High-Side Drivers for Automotive
STMicroelectronics VND70/VNQ70/VN9D High-Side Drivers for Automotive Applications are dual/quad channels using ST proprietary VIPower® M0-7 technology. The high-side drivers provide protection and diagnostics by driving 12V automotive grounded loads through a 3V and 5V CMOS-compatible interface.
Load current limitation, overload active management by power limitation, and overtemperature shutdown with configurable latch-off are integrated advanced protective functions available in the VND70/VNQ70/VN9D high-side drivers. In case of fault or disabled latch-off functionality, a FaultRST pin unlatches the output. During the module low-power mode and external sense resistor sharing, a sense enables pin allows OFF-state diagnosis to be disabled.
The VN9D, M0-9T technology devices feature digital current and chip temperature sensing for automotive applications powered by 12V battery tracks.
