STMicroelectronics EV-VNF1048F Controller Evaluation Board
STMicroelectronics EV-VNF1048F Controller Evaluation Board can be connected to an EV-SPC582B MCU evaluation board to create an intelligent high-side switch for 12V, 24V, and 48V automotive applications. The STMicroelectronics EV-VNF1048F comes pre-assembled with a VNF1048F high-side switch controller. The onboard minimum set of electrical components (per datasheet recommendation) enables the user to connect the load directly, the power supply, and the microcontroller without additional effort in external component design and connection.
