EUP3545/A USB Power-Distribution Switch with Fault Blanking DESCRIPTION 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 over.

EUP3545/A USB Power-Distribution Switch with Fault Blanking DESCRIPTION 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. Internal Under Voltage Lock-Out (UVLO) circuitry ensures that the switch remains off until valid input voltage is present. OC is open-drain output which is asserted when over-current or over-temperature event occurs. A 8ms fault-blanking feature enables the circuit to ignore momentary faults, such as those caused whe.
