Product details
Overview
TPS2000EDGKR from Texas Instruments is a 2A current-limited, single-channel power-distribution switch with N-channel MOSFET output stage, ±20% accurate fixed current limit, 2µs overcurrent response, and reverse current blocking. It operates from 2.7V to 5.5V input rails and supports USB-compliant hot-swap applications requiring short-circuit protection in PC peripherals and embedded systems.
For engineers reviewing the TPS2000EDGKR datasheet, TPS2000EDGKR pinout, TPS2000EDGKR application, or TPS2000EDGKR equivalent, this device delivers predictable fault current limiting, deglitched fault reporting, built-in soft-start, and thermal shutdown at 155°C - critical for reliable 5V rail distribution in space-constrained designs.
Technical Context
The TPS2000EDGKR integrates an internal charge pump to drive its N-channel MOSFET, enabling low RDS(ON) (70–105 mΩ) without external gate bias. Its constant-current limiting engages within 1.5 µs during output short circuits, maintaining safe IOUT at 2.8 A (typical) across –40°C to 125°C junction temperature.
It features active-low open-drain FLT signaling with 6–12 ms deglitching, output discharge via 500 Ω (typical) pulldown, and undervoltage lockout with 2.6 V turn-on threshold and 75 mV hysteresis - all implemented in an 8-pin HVSSOP PowerPAD™ package optimized for thermal performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 2 A - supports sustained load delivery for USB downstream ports and peripheral power rails |
| Current Limit Accuracy | ±20% - ensures predictable fault current under all operating conditions without calibration |
| RDS(ON) | 70–105 mΩ - minimizes conduction loss and voltage drop at full 2 A load on 3.3V/5V rails |
| Overcurrent Response Time | 1.5 µs - enables rapid fault containment before upstream supply collapse or damage |
| Input Voltage Range | 2.7 V to 5.5 V - compatible with standard logic-supply domains including USB 2.0 and industrial 3.3V/5V systems |
| Thermal Shutdown Threshold | 155°C (rising) - protects against sustained overload by cycling off until junction cools 10°C |
| FLT Deglitch Time | 6–12 ms - suppresses false fault assertions during startup transients or capacitive load surges |
Pinout & Package
TPS2000EDGKR is housed in an 8-pin HVSSOP (DGN) package with exposed PowerPAD™ thermal pad. The package measures 3.00 mm × 3.00 mm and requires soldering the PowerPAD to a GND plane for optimal thermal performance (RθJA = 51.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, GND | Ground reference | Primary return path for power and logic; connects to PCB ground plane and PowerPAD |
| 2, 3, IN | Power input | Dual-source input pins tied internally; accepts 2.7–5.5 V; requires local 0.1 µF ceramic bypass |
| 4, EN/EN | Enable control | Active-high logic input (VIH = 1.8 V min); enables switch and internal charge pump when high |
| 5, FLT | Fault indicator | Open-drain output asserted low during overcurrent or overtemperature; requires pull-up resistor |
| 6, 7, 8, OUT | Switched output | Three parallel output terminals tied internally; drives load with controlled rise/fall times |
| PowerPAD | Thermal & electrical ground | Exposed copper pad beneath package; must be soldered to GND plane for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft start | Controls output rise time (0.4–1.5 ms) to limit inrush current into heavy capacitive loads like USB hubs |
| Reverse current blocking | Prevents backflow from VOUT to VIN when disabled - eliminates need for external blocking diode |
| Output discharge | 500 Ω typical pulldown discharges load capacitance upon disable, preventing floating or latch-up states |
| UL Listed & CB-File E169910 | Meets safety certification requirements for end-equipment compliance in commercial and industrial systems |
| Fast overcurrent response | 1.5 µs detection-to-limit activation ensures upstream supply stability during sudden shorts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar power-distribution switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2001EDBVR | Same 2A current rating and functional spec, but in 5-pin SOT-23 (DBV) package; no PowerPAD™, higher RθJA (184.6°C/W) | Limited to lower-power or thermally relaxed layouts; lacks thermal pad for high-duty-cycle operation | Select when board space is constrained and thermal load is light; avoid for continuous 2A in ambient >60°C |
| TPS2041BDGNR | 1A rated, 100 mΩ RDS(ON), same DGN package; includes auto-retry fault mode instead of latched shutdown | Suitable for lower-current peripherals where fault recovery without host intervention is required | Choose for self-healing behavior in non-critical loads; not a direct replacement due to halved current capability |
Compared with TPS2000EDGKR, TPS2001EDBVR trades thermal performance for footprint reduction, while TPS2041BDGNR offers fault autonomy at the cost of current capacity - making TPS2000EDGKR optimal for thermally demanding, fixed 2A USB or industrial rail switching.

FAQ
What is the maximum continuous output current supported by the TPS2000EDGKR?
The TPS2000EDGKR supports a continuous output current of 2 A under recommended operating conditions (2.7 V to 5.5 V input, –40°C to 125°C junction temperature). Its current limit is fixed at 2.8 A (typical) with ±20% accuracy, ensuring consistent fault containment without external components. This rating is validated across all input voltages and temperatures specified in the datasheet.
Does the TPS2000EDGKR require an external gate driver or charge pump circuitry?
No, the TPS2000EDGKR integrates a fully self-contained charge pump and gate driver for its internal N-channel MOSFET. This eliminates the need for external bias supplies or driver ICs, simplifying layout and reducing BOM count. The charge pump automatically activates when the EN pin is asserted, enabling full 2 A switching with minimal external components.
How does the FLT pin behave during overcurrent and thermal events?
The FLT pin on the TPS2000EDGKR is an active-low open-drain output that asserts low during overcurrent or overtemperature conditions. It features 6–12 ms deglitching on both edges to prevent false triggers. FLT goes high-impedance when the device is disabled or in UVLO, and clears immediately upon disable - enabling precise fault isolation and host-controlled recovery.
Can the TPS2000EDGKR be used with 3.3V-only systems?
Yes, the TPS2000EDGKR operates across 2.7 V to 5.5 V input voltage range, making it fully compatible with 3.3V-only systems. Its enable threshold (VIH = 1.8 V min) and current limit performance (2.8 A typical) are maintained at 3.3 V, and RDS(ON) remains within 70–105 mΩ - ensuring efficient power delivery without derating.
What is the role of the PowerPAD™ in the TPS2000EDGKR DGN package?
The PowerPAD™ on the TPS2000EDGKR is an exposed thermal pad electrically connected to GND and designed to be soldered directly to the PCB ground plane. It reduces junction-to-board thermal resistance to 25.2°C/W, enabling reliable 2 A operation in compact layouts. Leaving it unconnected degrades thermal performance significantly and risks thermal shutdown under sustained load.
