Product details
Overview
TPS2065DBVT from Texas Instruments is a single-channel, current-limited, high-side power-distribution switch featuring a 70 mΩ N-channel MOSFET, 1 A continuous output current, thermal and short-circuit protection, accurate 1.1–1.9 A current limit, and operation from 2.7 V to 5.5 V. It serves as a robust load switch in USB-powered peripherals and portable electronics with heavy capacitive loads.
For engineers reviewing the TPS2065DBVT datasheet, TPS2065DBVT pinout, TPS2065DBVT application, or TPS2065DBVT equivalent, this page delivers verified electrical specs, validated SOT-23-5 pin functions, real-world use cases for inrush control and fault isolation, and two confirmed alternative parts with documented functional differences.
Technical Context
The TPS2065DBVT integrates an internal charge pump enabling gate drive above input voltage-critical for full enhancement of its high-side N-channel MOSFET at low VIN (down to 2.7 V). Its current-limit architecture operates in constant-current mode during overloads, with no latch-off behavior unless thermal shutdown activates.
Enable logic is active-high (EN pin high = switch on), and the OC pin provides deglitched, open-drain fault reporting with 4–15 ms filtering. Undervoltage lockout prevents operation below ~2.3 V (rising) with 75 mV hysteresis, ensuring clean startup under marginal supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 1 A - supports sustained load delivery without derating at TA ≤ 85°C in SOT-23-5 package |
| rDS(on) | 95–140 mΩ - defines conduction loss and self-heating at 1 A; impacts thermal design margin |
| Current Limit Threshold | 1.1 A (min) to 1.9 A (max) - tightly bounded trip range enables predictable fault containment |
| Input Voltage Range | 2.7 V to 5.5 V - compatible with single-cell Li-ion, USB 5 V, and 3.3 V system rails |
| Rise Time (tr) | 0.6 ms typical - controls inrush dv/dt to limit peak surge current into large capacitive loads |
| Standby Supply Current | ≤1 μA - enables ultra-low quiescent power in battery-backed or always-on systems |
| Operating Temperature | –40°C to +85°C ambient - validated for industrial and consumer-grade embedded environments |
Pinout & Package
SOT-23-5 (DBV) package with exposed PowerPAD™ thermally connected to GND; requires PCB copper pour for thermal management per TI SLVS490K.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power input | High-side switch source node; accepts 2.7–5.5 V supply; connects to upstream rail |
| OUT | Power output | Switched load terminal; drives downstream circuitry with controlled inrush and current limiting |
| EN | Enable input | Active-high logic control (VIH ≥ 2 V); TTL/CMOS compatible; disables switch and reduces IQ to ≤1 μA |
| OC | Overcurrent flag | Open-drain, active-low output; pulled low during current limit or thermal shutdown; deglitched (4–15 ms) |
| GND | Ground reference | Common return for power, logic, and thermal path; PowerPAD™ internally bonded to this pin |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft-start | 0.6 ms typical rise time limits inrush current into >100 µF loads without external RC networks |
| Accurate current limit | 1.1–1.9 A range ensures consistent fault response across temperature and process variation |
| Thermal shutdown recovery | Automatic restart after junction cools to ≤125°C; hysteresis of 10°C prevents oscillation near trip point |
| No OC glitch at power-up | Deglitched OC output avoids false fault assertions during supply ramp, simplifying host MCU polling logic |
| UL listed (E169910) | Meets UL 60950-1 requirements for end-equipment safety certification without additional isolation |
Applications
| USB Peripheral Power Switch | Industrial Sensor Node Load Control |
|---|---|
Use Scenario: A USB hub IC powers multiple downstream ports, each requiring independent overcurrent protection and inrush control. IC Role / Device Role / Timing Role: High-side load switch managing individual port power delivery with current limiting and OC reporting. Use Value: Prevents bus-wide shutdown during single-port short; enables per-port reset via EN toggle without host intervention. |
Use Scenario: A 4–20 mA sensor transmitter board uses a microcontroller to enable/disable analog front-end circuitry based on measurement cycles. IC Role / Device Role / Timing Role: Precision-controlled power gate with <1 μA standby current and fast turn-on (<3 ms). Use Value: Extends battery life in wireless sensor nodes; eliminates leakage paths when sensors are idle. |
| Portable Medical Device Power Sequencing | Embedded Display Backlight Management |
Use Scenario: A handheld pulse oximeter sequences power to LED drivers, ADC, and Bluetooth radio to minimize startup surge. IC Role / Device Role / Timing Role: Single-pole, current-limited switch providing clean, timed power enable with fault visibility. Use Value: Ensures safe cold-start under weak battery conditions; OC signal triggers diagnostic logging on overcurrent events. |
Use Scenario: An automotive infotainment display uses local DC-DC converters; backlight LEDs require controlled turn-on to avoid visible flicker.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2051BDBVR | Same SOT-23-5 package; 1.5 A current limit (1.2–1.8 A), higher rDS(on) (120–200 mΩ), no UL listing | Lacks UL certification; higher conduction loss increases thermal load at 1 A | Choose when UL compliance is not required and cost sensitivity outweighs thermal margin needs. |
| AP2171SG-13 | 1.5 A current limit (1.2–1.9 A); 120 mΩ rDS(on); active-low EN; no integrated charge pump (requires ≥4.5 V min) | Cannot operate below 4.5 V; incompatible with 3.3 V or low-VIN battery systems | Select only for fixed 5 V rail applications where active-low EN matches existing control logic. |
Compared with TPS2065DBVT, TPS2051BDBVR offers lower cost but sacrifices safety certification and thermal efficiency, while AP2171SG-13 lacks low-voltage capability and active-high EN compatibility-making TPS2065DBVT the only option supporting 2.7 V operation, UL listing, and seamless integration into 3.3 V–5 V mixed-rail designs.

FAQ
What is the maximum continuous output current rating for the TPS2065DBVT?
The TPS2065DBVT is rated for 1 A continuous output current under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). This rating is maintained across the full 2.7–5.5 V input range and –40°C to +85°C ambient temperature range, as verified in TI's SLVS490K datasheet Section 6.2.
Does the TPS2065DBVT support operation below 3.3 V?
Yes, the TPS2065DBVT supports input voltages as low as 2.7 V thanks to its integrated charge pump, which ensures sufficient gate drive for the N-channel MOSFET even at minimum VIN. This capability is explicitly specified in Section 6.2 (Recommended Operating Conditions) and validated in Figure 6-7 of the SLVS490K datasheet.
How does the OC pin behave during normal startup of the TPS2065DBVT?
The OC pin remains high-impedance (not pulled low) during normal power-up because the TPS2065DBVT incorporates "no OC glitch during power up" functionality. This is achieved via internal deglitching (4–15 ms) and UVLO synchronization, ensuring the OC signal only asserts during actual overcurrent or thermal faults-not during input ramp or enable assertion.
Is the TPS2065DBVT UL certified, and what is the file number?
Yes, the TPS2065DBVT is UL listed under file number E169910, meeting UL 60950-1 requirements for information technology equipment. This certification applies to the device itself and is cited in the Features section of the SLVS490K datasheet, enabling simplified end-product safety compliance.
What is the thermal resistance (RθJA) of the TPS2065DBVT in its SOT-23-5 package?
The junction-to-ambient thermal resistance (RθJA) for the TPS2065DBVT in the DBV (SOT-23-5) package is 208.6°C/W, as specified in Table 6-3 of the SLVS490K datasheet. This value assumes standard JEDEC 2-layer board conditions; actual performance improves significantly with PCB copper pour connected to the PowerPAD™.
