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 undervoltage lockout for each channel. 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.

  • 3.0V to 5.5V input voltage range
  • 500mA continuous load current per channel
  • 2.6V undervoltage lockout
  • 1.25A short-circuit current limit
  • 100mΩ maximum on-resistance
  • 75µA on-state supply current
  • 1µA shutdown current
  • Output can be forced higher than input
  • (off-state)
  • Thermal shutdown
  • Slow turn on and fast turn off
  • Active-high version: SP2525A-1
  • Active-low version: SP2525A-2
