EC9521 USB Power-Distribution Switches

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.
