The low limit of the current limit threshold of the XRP2525 and XRP2526 allows a minimum current of 0.9A through the MOSFET switches. The XRP2525 and XRP2526 devices are respectively single and dual channel integrated high-side power distribution switches that can be used in any self or bus powered USB applications. They are compliant with the latest USB 3.0 specifications. The reverse current protection feature prevents current to flow from OUT to IN when the device is disabled. When an overcurrent condition is detected, the output current is limited to a constant current limit threshold value and output voltage is reduced accordingly. Triggering the current limit function is signaled by the Error Flag after 10ms of blanking time period. INPUT & OUTPUT Placing bulk capacitances of at least 47μF and 10μF at the input and output pins respectively reduces power supply transients under heavy current load conditions. UNDER-VOLTAGE LOCKOUT Under-voltage lockout function (UVLO) keeps the internal power switch from being turned on until the power supply has reached at least 1.68V, even if the switch is enabled. Upon detection of an input voltage below approximately 1.68V, the power switch is turned off while a fault condition is reported by the error flag signal. It is important to place a 1μF ceramic bypass capacitor from IN to GND as close as possible to the device in order to control supply transients. Furthermore, bypassing the output pin with a 0.1μF to 1μF ceramic capacitor improves the device response to short-circuit transients. THERMAL PROTECTION Internal thermal sensing circuitry monitors the operating temperature of the device for each channel independently. Upon detection of a temperature in excess of 135°C, the power switch for the given channel is disabled preventing any damages to the device while a fault condition is reported by the error flag signal. A built-in 10°C hysteresis allows the device to cool down to 125°C before resuming normal operations on the faulty channel at which point the error flag signal is cleared. ERROR FLAG The error flag signal (FLGX output pin) is an open-drain output and is pulled low (active low) upon detection of the following conditions: • • • Over-current condition Over-temperature condition Under voltage lockout condition Over-temperature and under voltage lockout conditions are flagged immediately while the over – current condition is reported only if this condition persists continuously for longer than the blanking time of 10ms. The blanking time prevents erroneous reporting of current faults due to brief output current spikes. TEST CIRCUIT Once activated, the error flag signal remains low until all fault conditions have been removed and is independent for each individual channel. CURRENT LIMIT The current limit threshold is preset internally. It protects the output MOSFET switches from 10/12 Rev. 1.1.1 XRP2525 - XRP2526 Single/Dual Channel USB 3.0 Power Distribution Switch PACKAGE SPECIFICATION 8-PIN NSOIC 11/12 Rev. 1.1.1 XRP2525 - XRP2526 Single/Dual Channel USB 3.0 Power Distribution Switch REVISION HISTORY Revision Date Description 1.0.0 05/13/2011 Initial release of datasheet 1.1.0 07/14/2011 Corrections of typographical errors 1.1.1 11/04/2019 Updated to MaxLinear logo.
