TD9519

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.
