GENERAL 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
70m ? 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 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 rise time limits
inrush current during hot plug-in, minimizing
EMI and preventing the voltage at the
upstream port from dropping excessively.
The SP2525A is offered in a RoHS compliant
“green”/halogen free 8-pin NSOIC package.
