DESCRIPTION
The SP2525 device is a single +3.0V to +5.5V USB Supervisory Power Control Switch ideal
for self-powered and bus-powered Universal Serial Bus (USB) applications. The SP2525
device has low on-resistance (80mΩ typical) and can supply 500mA minimum. The fault
currents are limited to 2.0A typical and the flag output pin is available to indicate fault
conditions to the USB controller. The 1ms soft start of the SP2525 device will eliminate any
momentary voltage drop on the upstream port that may occur when the switch is enabled in
bus-powered applications. The thermal shutdown feature will prevent permanent damage to
the SP2525 device when subjected to excessive current loads. The under voltage lockout feature
will ensure that the SP2525 device will remain off unless there is a valid input voltage present.
