What are the key features of TPS2065CDBVT-2?
- 500 mA adjustable current-limit protects downstream loads from short-circuit faults without external fuses or resettable PTCs
- 2.7 V to 5.5 V input range covers both 3.3 V and 5 V USB and embedded power distribution rails
- 130 mOhm maximum on-resistance minimizes I²R power loss at full 500 mA load current in battery-powered designs
- Compact 5-pin SOT-23 package with active-high enable pin simplifies software-controlled load switching on space-constrained boards
What is TPS2065CDBVT-2 used for?
The TPS2065CDBVT-2 is used as a software-controlled power switch for USB port protection, peripheral load switching, and hot-plug management in laptops, tablets, and embedded systems. Its 500 mA current limit and 2.7 V to 5.5 V input range make it ideal for protecting 3.3 V and 5 V power rails feeding sensors, displays, and memory modules. The 5-pin SOT-23 footprint enables dense multi-channel power distribution designs in mobile and IoT devices where board space is limited.

Frequently Asked Questions
What current limit does the TPS2065CDBVT-2 enforce, and how does it respond to an overload?
The TPS2065CDBVT-2 enforces a 500 mA current limit on its output. When a short circuit or overload exceeds this threshold, the device enters a current-limiting mode and reduces its output to protect the source supply and downstream load. Once the fault clears, the switch automatically recovers, eliminating the need for manual intervention or replaceable fuses in 3.3 V and 5 V distribution networks.
What is the on-resistance of the TPS2065CDBVT-2, and how does it affect power efficiency?
The TPS2065CDBVT-2 has a maximum on-resistance of 130 mOhm, which produces only 65 mW of conduction loss at the full 500 mA rated current. This low drop-out characteristic preserves supply headroom on 3.3 V rails, making it suitable for battery-powered IoT and wearable devices where every milliwatt of efficiency contributes to extended run time.
Over what input voltage range does the TPS2065CDBVT-2 operate reliably?
The TPS2065CDBVT-2 operates reliably across an input voltage range of 2.7 V to 5.5 V, encompassing single-cell Li-Ion battery outputs, regulated 3.3 V rails, and standard 5 V USB bus voltages. This wide range lets a single part serve as a load switch across multiple power planes in a mixed-voltage embedded design without needing separate devices for each rail.
How does the TPS2065CDBVT-2 fit into a USB port protection circuit compared to a discrete MOSFET solution?
The TPS2065CDBVT-2 integrates a MOSFET switch, 500 mA current limiter, and 130 mOhm on-resistance in a single 5-pin SOT-23 package, replacing a discrete MOSFET, sense resistor, and comparator circuit. This integration reduces the component count from 5 or more parts to 1, cuts PCB area, and provides a factory-calibrated 500 mA trip point that discrete solutions cannot match without additional trimming.
