Eutech Microelectronics EUP3545A

The EUP3545/A is an incorporated 100mΩ P-channel MOSFET power-distribution switch for self-powered and bus-powered Universal Serial Bus (USB) applications. When the output load exceeds the current-limit threshold or a short is present, the device limits the output current to safe level by switching into a constant-current limit mode with fold back, pulling the over-current ( OC ) logic output low. When continuous heavy overloads or short-circuits increase the power dissipation in the switch, causing the junction temperature to rise, a thermal protection circuit shutdown the switch to prevent damage.
