XRP2527：Single Channel Adjustable Current Power Distribution Switch

The XRP2527 is a single channel integrated high-side power distribution switch with channel enable, channel fault flag and precise programmable current limit threshold. A wide 1.75V to 5.5V input voltage range allows for operations from industry standard 1.8V, 3.3V and 5V power rails.

Current limit threshold can be programmed accurately via an external resistor. A simple setting optimizes the XRP2527 for use in USB 2.0 or 3.0 compliant VBUS power distribution architectures. The power-switch rise and fall times are controlled to minimize current surges during turn on/off.

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