Status: Draft schematic in progress. A consumer USB-C powered temperature and relative humidity sensor node with Wi-Fi and Bluetooth Low Ene...
Architecture review agrees with a USB-C sink plus real VBUS protection and a buck regulator; I’m selecting a low-power certified Wi‑Fi/BLE module rather than a hot LDO-based ESP32-style power tree.
Worked for 1 min 50 sec
Thought for 18 sec — Choosing components for low-power MCU
Found 3 results for Find Flux library USB input eFuse or protection switch IC for 5 V USB-C sink with adjustable/current limit around 0.75 to 1 A, overvoltage protection threshold above normal USB 5.25 V and below 9 V, undervoltage lockout, reverse current blocking, soft-start/inrush control, active SMD part. Prefer TI TPS2595 TPS2596 TPS2594 AP2265 AP22802 style eFuse..
Found 10 results for TPS2595.
Found 10 results for TPS2596.
Found 2 results for AP22652.
Found 4 results for NCP361.
