Dual-Channel USB 3.0 Power Distribution Switch


The XRP2526 is a dual-channel integrated high-side power distribution switch with independent enables and fault flags. A wide 1.75V to 5.5V input voltage range allows for operations from industry standard 1.8V, 3.3V and 5V power rails.

Optimized for USB VBUS power distribution, the XRP2526 is compliant with the USB 3.0 specification and can be used in any self powered USB applications. The power-switch rise and fall times are controlled to minimize current surges during turn on/off.

Built-in overcurrent, undervoltage lockout (UVLO), reverse current and over temperature protections insure safe operations under abnormal operating conditions.

The XRP2525 is pin and function compatible to Exar's SP2526A.
