General Description
Features
The TD9516/TD9517/TD9518/TD9519 series of power switches are designed for USB applications. The 62mN-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. When VOUT drops below 1.5V, the devices limit the current to a lower and safe level. The over-temperature protection limits the junction temperature below 140oC in case of short circuit or over load conditions.
