What are the key features of TPS2033D?

Ultra-low 33 mΩ on-resistance minimizes conduction losses and voltage drop on USB power rails
Integrated overcurrent, thermal, and undervoltage lockout protection in a single IC
2.7 V minimum operating voltage supports both 3.3 V and 5 V USB host controller designs

What is TPS2033D used for?

The TPS2033D is ideal for USB hub and host controller designs where each downstream port needs independently switched and protected 5 V power. Its built-in overcurrent limiting at 1.5 A prevents damage to the host system from short circuits or excessive load during device enumeration. It is also used in embedded systems and industrial panels to gate power to USB peripherals, reducing inrush current and protecting the main power rail.

Frequently Asked Questions

What is the on-resistance of TPS2033D and how does it affect USB port voltage compliance?

The TPS2033D has a 33 mΩ on-resistance, which at a full 500 mA USB load causes only a 16.5 mV drop. This keeps the downstream port voltage well within the USB 2.0 specification of 4.75 V minimum from a 5 V supply, ensuring reliable device operation even at maximum standard current draw.

How does the TPS2033D protect a USB host against a shorted downstream device?

The TPS2033D monitors output current continuously and limits it to approximately 1.5 A when a short circuit or overload is detected. It also includes thermal shutdown that activates when junction temperature exceeds roughly 140°C, cutting off the port automatically and protecting both the IC and the 5 V rail from sustained fault conditions.

Can TPS2033D be used in a 3.3 V system that switches a 5 V USB power rail?

Yes. The TPS2033D input logic threshold is compatible with 3.3 V control signals while the power path handles up to 5 V at 1.5 A. The 2.7 V minimum supply voltage means the enable input from a 3.3 V microcontroller can directly control the switch without level shifting, simplifying the 8-pin SOIC design integration.
