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.
