XRP2527

July 2011 XRP2527 - XRP2528 Single/Dual Channel Adjustable Current Power Distribution Switch Rev. 1.1.0 GENERAL DESCRIPTION The XRP2527 and XRP2528 devices are respectively single and dual channel integrated high-side power distribution switches with independent enables, fault flags and precise programmable current limit thresholds. A wide 1.8V to 5.5V input voltage range allows for operations from industry standard 1.8V, 3.3V and 5V power rails. Current limit thresholds can be programmed accurately and independently for each channel via an external resistor. A simple setting optimizes the XRP2527 and XRP2528 for use in USB 2.0 or 3.0 compliant VBUS power distribution architectures. These devices can be used in any self or bus powered USB applications. 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 abnor...
