The SP2526 device is a dual +3.0V to +5.5V USB Supervisory Power Control Switch ideal for self-powered and bus-powered Universal Serial Bus (USB) applications. Each switch has low on-resistance (80m typical) and can supply 500mA minimum. The fault currents are limited to 2.0A typical and the flag output pin for each switch is available to indicate fault conditions to the USB controller. The 1ms soft start will eliminate any momentary voltage droop on the upstream port that may occur when the switch is enabled in bus-powered applications. The thermal shutdown feature will prevent damage to the device when subjected to excessive current loads. The undervoltage lockout feature will ensure that the device will remain off unless there is a valid input voltage present.
