Key Features
- 1.0 A continuous current capability with integrated overcurrent protection guards downstream USB peripherals without external fuses
- Output discharge feature pulls load capacitor to ground when disabled, ensuring fast power-off for USB port sequencing requirements
- Active-high enable logic and 4.5 V–5.5 V operating range provide direct compatibility with 5 V USB host controller GPIO signals
Applications
The TPS2065CDGNR is designed for USB port power management in laptops, embedded SBCs, and USB hubs where each port needs independently controlled, protected 5 V output. Its output discharge function ensures downstream devices power off cleanly during hot-plug events, meeting USB specification requirements. The 8-pin MSOP (S-PDSO-G8) footprint makes it ideal for compact USB hub or charging station PCB designs.

Frequently Asked Questions
How does TPS2065CDGNR protect a USB port from overcurrent faults in a 4-port USB hub design?
The TPS2065CDGNR integrates an internal current-limiting circuit that clamps output current at a threshold above the rated 1.0 A continuous limit, preventing damage to the host controller and wiring during short-circuit or overload events. When the fault clears, the switch can auto-retry or latch off depending on its configuration, and the active-high enable allows a host GPIO to override and reset the port independently of the other 3 channels.
Why is the output discharge feature of TPS2065CDGNR important for USB compliance in hot-plug scenarios?
USB specifications require that Vbus drops to below 0.8 V within a defined time after a port is disabled, preventing a previously connected device from back-powering the host. The TPS2065CDGNR's output discharge function bleeds down the load capacitance (typically 10 µF to 100 µF) actively when the switch turns off, ensuring voltage falls within the compliant window without relying on the device's own leakage current.
What is the input voltage range of TPS2065CDGNR, and can it work with a slightly drooped 5 V USB supply?
The TPS2065CDGNR operates from 4.5 V to 5.5 V on its input, which spans the full USB 2.0 Vbus tolerance band of ±5% around 5 V. A supply drooping to 4.5 V still keeps the switch fully operational, making it robust against cable voltage drop in longer USB cable runs or during peak current draw of 1.0 A from the connected peripheral.
