1.5A Single-Channel USB 2.0 / USB 3.0 Power Distribution Switch


The XRP2523 is a single-channel integrated high-side power distribution switch optimized for self or bus-powered USB applications and compliant with the latest USB 3.0 specification. It accepts an input voltage between of 3.2V and 6.5V allowing for operations from industry standard 3.3V and 5V power rails.

The XRP2523 is provided with an enable pin with integrated soft-start while an error flag is available to indicate any fault conditions. With a low quiescent current as well as a small package, the XRP2523 is ideal for battery powered 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.

XRP2523 is offered in a RoHS compliant green/halogen free 5-pin SOT-23 package.
