Getting a BOM overview.
Completed 11 design checks — found 114 issues.
Thought for 42 sec — Verifying eFuse features
Read U2, TPS259530DSGT datasheets.
Thought for a moment
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

Implemented the schematic for the USB-C powered Wi‑Fi/BLE temperature/humidity node. It uses a SiWG917 Wi‑Fi/BLE 5.4 module, SHT41 T/RH sensor, USB-C sink input, TPS25940 true reverse-blocking eFuse with OVP/UVLO/OCP/soft-start, MP28301 3.3 V buck regulator, ESD protection, reset/ISP/SWD debug, I2C pull-ups, and status LED.
Created project files:
Open items:
- PCB layout/routing is not done yet, so airwire DRC errors are expected.
- Generic passives still need final manufacturer MPNs before manufacturing export.
- Layout must enforce the SiWG917 antenna keepout and thermal isolation around the SHT41.
Suggested next steps:
- Set board size/stackup and move into PCB placement.
- Place U1 at the board edge with antenna keepout and U4 away from heat sources.
- Route power, buck, I2C, SWD/UART, and USB-C protection paths.
- Assign final passive MPNs and run full DRC/manufacturing checks.
