Single Channel USB Power Distribution Switch
Rev. 2.1.0
GENERAL DESCRIPTION The SP2525A device is an integrated high-side power switch ideal for self-powered and buspowered 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 under voltage 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...
