DESCRIPTION

The SP2525A device is an integrated high-side power switch ideal for self-powered and bus-

powered Universal Serial Bus (USB) applications. The high-side switches are MOSFETs with

70mΩ R^DS(ON), which meets USB voltage drop requirements for maximum transmission wire

length. Multi-purpose open-drain fault flag output indicates over-current limiting, thermal

shutdown, or undervoltage lockout. Output current is typically limited to 0.85A below the 5A

safetyrequirement, andthethermalshutdownfunctionshutstheswitchofftopreventdamage

under overcurrent conditions. Guaranteed minimum output rise time limits inrush current

during hot plug-in, minimizing EMI and preventing the voltage at the upstream port from

dropping excessively.
