The new TPS204x /5x family of fully independent power distribution switches are designed to meet both the needs of USB and general power distribution applications. This device family integrates the multiple features required for implementing a USB power interface into a single package.

TI’s patented dual temperature threshold circuit enables the switches in the TPS204x/5x family to function individually. This permits dual and quad switch packages to detect and disable only the switches that are in over-current, allowing other USB devices to continue normal operation. Other independent features include:

• Enables (low or high) — allows the power switches to be turned on or off.
• Over-current response — provides logic feedback during over current conditions.
• Low r_DS(on) (135 m max) enables full USB compliance without increasing the supply voltage.

The TPS204x/5x family of devices provides a cost effective means of switching power to USB ports and other power distribution applications.

This family is also available in SOIC and DIP packages.
