USB power switch for downstream port protection
The Maxim MAX1694EUB-TG069 is a USB current-limited switch designed to protect host-side USB ports and powered peripherals from overcurrent and short-circuit faults. It integrates a P-channel MOSFET switch with a current-sense and limiting circuit, so the upstream supply sees a controlled load even when the downstream device draws a fault current. This part is suited for USB hubs, docking stations, and any host port that needs to stay alive when a peripheral fails.
