DATASHEET

General Description

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 the current to a lower and safe level. The

over-temperature protection limits the junction temperature

conditions.Other features include a deglitched OCB output to

indicate the fault condition and an enable input to enable or

disable the device.
