STMicroelectronics EV-VNF1248F Evaluation Board
STMicroelectronics EV-VNF1248F Evaluation Board facilitates the integration of a high-side switch controller with intelligent fuse protection into prototype circuitry (32A maximum current allowed, limitation due to the connector used). The pre-assembled EV-VNF1248F board includes the VNF1248F and the essential electrical components.
The STMicro EV-VNF1248F Board setup enables direct connections to the load, power supply, and microcontroller, eliminating the requirement for additional external component design and connections. When combined with the EV-SPC582B board flashed with the STSW-EV-VNF1248F, a comprehensive evaluation tool is formed for assessing the performance of the EVVNF1248F high-side switch.
