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.  62mΩ High Side MOSFET  Wide Supply Voltage Range: 2.7V to 5.5V  Current-Limit and Short-Circuit Protections  Over-Temperature Protection  Fault Indication Output  Enable Input  Lead Free and Green Devices Available Applications  Notebook and Desktop Computers  USB Ports  High-Side Power Protection Switches Pin Configurations SOT-23-5(Top View) TD9516A/TD9517A SOT-23-5(Top View) TD9518A/TD9519A SOT-23-5(Top View) TD9516B/TD9517B SOT-23-5(Top View) TD9518B/TD9519B Figure Pin Configuration of TD9516/TD9517/TD9518/TD9519(Top View) October, 20, 2011.

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. Pulling this pin to high will enable the device and pulling this pin to low will disable device. The EN pin cannot be left floating. Enable Input. Pulling this pin to high will enable the device and pulling this pin to low will disable device. The EN pin cannot be left floating. Power Supply Input. Connect this pin to external DC supply.
