General Description

The EC9521 power switches are designed for USB applications.
The 35mΩ N-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.
