The SP2525A device is an integrated high-side power switch ideal for self-powered and bus-powered universal Serial bus (USB) applications. And in a RoHS-compliant "green"/halogen-free 8-pin NSOIC package. The high-side switch is a 70mΩ RDS(ON) mosfet that meets the USB voltage drop requirement for the maximum transmission line length. Multipurpose leak-open fault flag Output indicates over current limit, hot stop, or undervoltage lock.
Pin assignment
The output current is usually limited to 0.85A below 5A safety requirements, and the thermal shut-off feature turns off the switch to prevent damage under overcurrent conditions. Ensure minimum output upturn time, limit inrush current during hot swap, reduce electromagnetic interference, and prevent excessive voltage drop of upstream ports.
