TD9516---多口USB限流IC

the td9516/td9517/td9518/td9519 seriesof power switches are designed for usb applications. the62mw n-channelmosfet power switch satisfies thevoltage drop re of usbspecification.

the protectionfeatures include current-limit protection, short-circuit protection, andover-temperature protection.the device limits the output current atcurrent limit threshold level. whenvout drops below 1.5v, the deviceslimit the current to a lower andsafe level. the over-temperature protection limits thejunction temperature below 140oc in case of short circuit orover load conditions.other features include a deglitched ocb outputto indicate the fault condition and anenable input to enable or disable thedevice
