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 RDS(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
safety requirement, and the thermal shutdown function shuts the switch off to prevent damage
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.
