Searching for eFuse solutions
I need to address the issue with TPS2596 that requires fixing since the user needs the reverse. It looks like I have to replace or add an ideal diode. To do that, I should search for a part with back-to-back eFuse in the library. It’s essential to find the right replacement to meet the user's requirements. Let’s get started on that!
The core schematic has been drafted with a SiWG917 Wi‑Fi/BLE module, SHT41 temperature/humidity sensor, USB‑C 5 V input, protected power path, and 3.3 V buck rail. Firmware, bring-up, and regulatory planning were also started.
I can’t inspect the attached text or continue verification because no ACUs are currently available. Remaining work: review the attachment, finish ERC/DRC remediation, confirm protection and power-budget ratings for 0.5–3 A USB sources, and complete PCB placement/routing.
