What are the key features of TPS2065CDGNR-2?
- Single-channel current-limited power switch operating from 4.5 V to 5.5 V for USB 2.0 power distribution
- Integrated overcurrent and thermal protection safeguard downstream USB devices without external components
- 8-pin MSOP (MSOP-8) package minimizes PCB footprint in USB hub and host controller designs
What is TPS2065CDGNR-2 used for?
The TPS2065CDGNR-2 is used in USB host controllers, laptop charging ports, and embedded systems requiring protected 5 V power distribution. Its current-limiting function prevents overcurrent damage to both host and peripheral devices during short-circuit events. The device is well suited for industrial and consumer electronics requiring reliable single-channel USB power switching in space-constrained layouts.

Frequently Asked Questions
What input voltage range does the TPS2065CDGNR-2 support and is it compatible with standard 5 V USB bus rails?
The TPS2065CDGNR-2 operates from 4.5 V to 5.5 V, covering the full USB bus voltage tolerance range of 5 V ±10%. This makes it directly compatible with standard USB 2.0 host and hub power rails without requiring an additional voltage regulator, simplifying single-supply USB power distribution designs.
How does the current-limiting feature of TPS2065CDGNR-2 protect USB peripherals during a fault condition?
When output current exceeds the programmed limit, the TPS2065CDGNR-2 clamps the output rather than immediately disconnecting, limiting inrush to a controlled level typically below 500 mA. If the fault persists and junction temperature rises above the thermal shutdown threshold of approximately 140°C, the device turns off and auto-retries when it cools, protecting both the switch and connected USB peripheral.
What package does TPS2065CDGNR-2 use and how does its footprint compare to larger SOT-23 power switch options?
The TPS2065CDGNR-2 uses an 8-pin MSOP (S-PDSO-G8) package with a body measuring roughly 3 mm × 3 mm, which is comparable to SOT-23 alternatives but offers 8 leads for additional control and fault-flag signals. The compact footprint enables placement close to USB connectors on 2-layer PCBs with limited routing space.
In which USB power delivery scenarios is TPS2065CDGNR-2 preferred over a simple PMOS discrete switch?
TPS2065CDGNR-2 is preferred over a discrete PMOS switch wherever automatic current limiting and thermal shutdown are required within a single 1 mm² footprint. A discrete PMOS and current-sense resistor approach needs at least 3 additional components, adding 5 mm² or more to board area, whereas TPS2065CDGNR-2 integrates protection for 1-channel USB ports operating at 5 V in a single 8-pin IC.
