Calculating resistor values
I need to replace some components in my circuit, specifically requiring RILIM for 1A with an equation that seems a bit off. For R = 88.7k, this gives 0.99A, so R3 must change from 909Ω to 88.7k. I also want to set up an OVP/UVLO divider using resistors R1, R2, R3 and see if I can repurpose the existing R5, R6, and R4. I need to calculate the appropriate values based on thresholds for VUV and VOV while ensuring everything fits correctly in the designed circuit.
Considering IMON resistor
I'm thinking about whether I need to add an IMON resistor to my circuit. If it's going to be unused, I might just leave it out altogether. It's important that I carefully evaluate its purpose, so I don't add unnecessary components. I want to keep the design clean and functional, so if the IMON resistor isn't needed, I should definitely skip it to simplify things. Let’s carefully decide based on the overall circuit requirements
i not view sample
The project schematic exists with the USB‑C connector, protected 5 V input, 3.3 V regulator, SiWG917 Wi‑Fi/BLE module, and SHT41 temperature/humidity sensor.
I can’t generate or display the sample right now because no ACUs are available. Remaining work: verify wiring/ERC, fix any schematic issues, organize the schematic visually, and complete PCB placement/routing.
