SP2525 - USB Power Control Switch from +3.0 V to +5.5 V
DESCRIPTION The SP2525 device is a single +3.0 V to +5.5 V power control switch ideal for USB monitoring of self-powered and bus-powered Universal Serial Bus (USB) applications. The SP2525 device has low on-resistance (80mW typical) and can deliver a minimum level of 500mA. The fault value is 2.0A current limited at typical and the flag output pin can be used to indicate fault conditions to the USB controller. The 1ms soft-start of the SP2525 device will eliminate any momentary switch-enabled bus-powered applications that may occur when the upstream port voltage drops. A thermal shutdown feature will prevent permanent damage to the SP2525device when subjected to excessive current loads. The undervoltage lockout feature will ensure that the SP2525 device will remain off unless there is a valid input voltage.
