Overview
Techcode® USB Power-Distribution Switches DATASHEET TD9516/TD9517/TD9518/TD9519 General Description Features The TD9516/TD9517/TD9518/TD9519 series of power switches are designed for USB applications.
The 62m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.
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.
Other features include a deglitched OCB output to indicate the fault condition and an enable input to enable or disable the device.

The output voltage follows the input voltage.
When ENB is high or EN is low, the output voltage is discharged by an internal resistor.
Ground.
Fault Indication Pin.
This pin goes low when a current limit or an over-temperature condition is detected after a 12ms deglitch time.
Enable Input.
