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 conditio...
