General Description

The EC9521 power switches are designed for USB applications. The 25mΩN-channel MOSFET power switch
satisfies the voltage drop requirements of USB specification.

The protection features include current-limit protection, short-circuit protection, and over-temperature protection. The device limits the output current at current limit threshold level.

The over-temperature protection limits the junction temperature below 140℃in case of short circuit or over load conditions. An enable input to enable or disable the device.
