The IMP2525 high-side power switch IC is designed for self-powered and bus-powered Universal Serial Bus (USB) power supply and power management applications. The IMP2525 conforms to USB standards with a low output switch ON-resistance (RON) and minimal voltage drop across the switch. The fault current is limited to 750mA typically, and a flag output conveys fault conditions to the local USB controller.The IMP2525 provides a "Soft-Start" function that ramps up the ONcurrent to eliminate any excessive voltage drop on the input side that could occur due to charging a capacitive load in bus-powered applications.Self-monitoring features include thermal shutdown to prevent
catastrophic switch failure from high-current loads and undervoltage lockout (UVLO) that insures that IMP2525 remains off unless there is a valid supply voltage present. The Enable input logic can be interfaced with both 3.3V and 5V logic. Both active-HIGH and active-LOW enable logic versions are available. The IMP2525 devices are available in 8-pin DIP and 8-pin SO packages.

IMP offers a complete family of USB power management products. For dual-switch applications see the IMP2526 data sheet and for quad-switch application, see the IMP2524. The single-switch IMP2525A features a 50% lower switch resistance, 0.07.
