DESCRIPTION

■ 1ms Soft-Start Power Up, Fast Turn Off

The SP2526A 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 (110mΩ typical) and can supply 500mA minimum. The fault currents are

limited to 1.0A typical and the flag output pin for each switch is available to indicate fault

conditions to the USB controller. 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.
