製品概要
概要
The EV-VNF1248F evaluation board simplifies the integration of a high-side switch controller with intelligent fuse protection into your prototype circuitry (MAX current allowed 32 A, limitation due to connector used). This pre-assembled board includes the VNF1248F, and the essential electrical components as recommended in the device datasheet. This setup allows for direct connections to the load, power supply, and microcontroller, eliminating the need for additional external component design and connections.
When used with the EV-SPC582B board flashed with the STSW-EV-VNF1248F, it forms a comprehensive evaluation tool for assessing the performance of EV-VNF1248F high-side switch.
