Product details
Overview
TPS25200DRVT from Texas Instruments is a 5V eFuse IC with precision adjustable current limit (85 mA–2.9 A), integrated 60 mΩ high-side MOSFET, 7.6 V overvoltage lockout, and 5.25–5.55 V output voltage clamp. It provides robust overcurrent, overvoltage, and thermal protection for USB-powered mobile devices and SSDs.
For engineers reviewing the TPS25200DRVT datasheet, TPS25200DRVT pinout, TPS25200DRVT application, or TPS25200DRVT equivalent, this page delivers verified electrical specs, functional mode behavior, fault response timing, package-validated thermal metrics, and real-world design guidance for hot-plug transient suppression and programmable current limiting in 5V bus protection.
Technical Context
The TPS25200DRVT implements dual overvoltage protection: a precision 5.4 V output clamp active between 5.4 V and 7.6 V input, and a hard 7.6 V input overvoltage lockout with 0.6 µs response. Its current-limit threshold is set by an external resistor (RILIM) with ±6% accuracy at 2.9 A and supports thermal cycling shutdown at 135°C (OTSD1) and absolute 155°C (OTSD2).
It integrates reverse-current blocking when disabled, 480 Ω typical output discharge resistance, deglitched FAULT reporting (8 ms overcurrent deglitch), and UVLO with 2.35 V turn-on threshold and 30 mV hysteresis - all operating across –40°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input voltage range | 2.5 V to 6.5 V operating; withstands up to 20 V DC without damage |
| Current limit range | Programmable 85 mA to 2.9 A via RILIM; ±6% accuracy at 2.9 A |
| Overvoltage clamp | 5.25–5.55 V at OUT; clamps during 5.4–7.6 V IN transients to protect downstream 5V logic |
| Overvoltage lockout | 7.6 V IN threshold (±0.85 V); disconnects load within 0.6 µs to prevent damage |
| rDS(on) | 60 mΩ typical at 25°C; enables ≤2.6 A continuous load current with <156 mW conduction loss at 2.6 A |
| Short-circuit response | 3.5 µs detection and current limiting; prevents bus collapse during sudden shorts |
| Thermal shutdown | Two-tier: 135°C (current-limit active) and 155°C (ambient); 20°C hysteresis for stable cycling |
Pinout & Package
TPS25200DRVT uses a 6-pin WSON (DRV) package, 2 mm × 2 mm, with exposed PowerPAD™ thermally connected to GND. The package supports high-power density PCB layouts with low θJB = 36.1°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Protected power output | Switched VOUT; connects to load; features integrated 480 Ω discharge path when disabled |
| EN (Pin 4) | Logic-level enable input | Active-high TTL/CMOS-compatible control; 1.9 V turn-on, 0.6 V turn-off, 330 mV hysteresis |
| FAULT (Pin 3) | Open-drain fault flag | Asserts low during overcurrent, overvoltage, or overtemperature; 8 ms deglitch for false-trigger immunity |
| ILIM (Pin 2) | Current-limit programming node | Sinks regulated current; sets IOS via external RILIM (33 kΩ–1100 kΩ); trace routing critical for accuracy |
| IN (Pin 6) | Input power rail | Accepts 2.5–6.5 V; tolerates 20 V; requires ≥0.1 µF ceramic bypass capacitor placed adjacent to pin |
| GND (Pin 5) | Ground reference | Electrical and thermal return; must be externally connected to PowerPAD™ for optimal thermal performance |

Applications
| USB Power Switching | Mobile Device Protection |
|---|---|
|
Use Scenario: Hot-plugging a 3G/4G data card into a 5 V USB port induces cable inductance transients exceeding 7 V.

Use Value: Eliminates need for external TVS diodes or bulk capacitors while protecting host and target device simultaneously. |
Use Scenario: Smartphones and tablets require reliable 5 V rail protection against adapter overvoltage and internal short circuits. IC Role / Device Role / Timing Role: TPS25200DRVT serves as intelligent load switch with programmable current limit and reverse-blocking capability. Use Value: Enables precise current budgeting (e.g., 2.1–2.9 A) and prevents back-feed from battery-backed peripherals during sleep mode. |
| Solid-State Drive (SSD) Power Control | 5 V Adapter-Powered Systems |
|
Use Scenario: SSDs drawing burst currents up to 2.6 A risk triggering upstream supply brownouts or damaging PCIe slot power delivery. IC Role / Device Role / Timing Role: TPS25200DRVT functions as current-limited power gate with soft-start and thermal foldback. Use Value: Limits inrush and steady-state current to match adapter rating; thermal cycling avoids catastrophic shutdown during sustained loads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2553DBVR | Fixed 1.5 A current limit; no programmability; same DRV package and pinout | Lacks adjustable current limit and overvoltage clamp; only provides overcurrent + thermal protection | Select when fixed 1.5 A limit suffices and board space reuse is prioritized over flexibility |
| TPS259211PWPT | Higher 5.5 V max input; 0.5–5.2 A programmable limit; 2.7 V min input; includes input voltage monitor | Supports wider VIN range and higher current; adds precision input voltage reporting via IMON pin | Choose for designs requiring >2.6 A, lower VIN operation, or telemetry-enabled power management |
Compared with TPS25200DRVT, TPS2553DBVR offers pin-to-pin compatibility but sacrifices programmability and overvoltage clamping, while TPS259211PWPT extends voltage/current range and adds telemetry - making TPS25200DRVT optimal for cost-sensitive, 5 V–focused USB and mobile applications needing precision clamp + adjustable limit in minimal footprint.

FAQ
What is the maximum continuous load current supported by the TPS25200DRVT?
The TPS25200DRVT supports up to 2.6 A continuous load current under recommended operating conditions (–40°C to +125°C, 2.5 V ≤ VIN ≤ 6.5 V). This rating assumes proper PCB thermal design - including connection of the PowerPAD™ to a sufficient copper area - and accounts for the 60 mΩ rDS(on) conduction loss. At 2.6 A, power dissipation remains within thermal limits when θJB ≤ 36.1°C/W is maintained.
How does the TPS25200DRVT respond to an input overvoltage event above 7.6 V?
When VIN exceeds 7.6 V, the TPS25200DRVT activates its overvoltage lockout (OVLO) circuit and disables the internal high-side MOSFET within 0.6 µs. This disconnects the load from the overvoltage source and asserts the FAULT pin low. The device remains latched off until VIN drops below the OVLO hysteresis threshold (~6.8 V), at which point it resumes normal operation if no other fault condition persists.
Can the TPS25200DRVT be used with input voltages below 2.5 V?
No - the TPS25200DRVT is not specified to operate below 2.5 V input. Its undervoltage lockout (UVLO) turns the device off when VIN falls below 2.35 V (typical), and the recommended minimum operating voltage is 2.5 V. Operation below this risks undefined behavior, incomplete current limiting, or failure to maintain output regulation. For sub-2.5 V applications, consider TI's TPS2592x or TPS2594x families.
What is the purpose of the ILIM pin on the TPS25200DRVT, and how is it used?
The ILIM pin on the TPS25200DRVT sources a regulated current that sets the output current-limit threshold. By connecting an external resistor RILIM from ILIM to GND, users program the current limit between 85 mA and 2.9 A. The relationship follows IOS ≈ 97399 / (RILIM + 30) mA (with RILIM in kΩ). TI recommends using 1% tolerance resistors in the 33 kΩ–1100 kΩ range and keeping PCB traces short to preserve accuracy.
Does the TPS25200DRVT provide reverse current blocking, and under what conditions?
Yes - the TPS25200DRVT provides reverse current blocking when disabled (EN = low). In this state, the internal high-side MOSFET is fully off, preventing current flow from OUT to IN even if VOUT > VIN. This feature protects upstream sources (e.g., USB hosts) from back-drive by powered peripherals or batteries. Reverse leakage is specified at 3–5 µA at 25°C, ensuring negligible standby power loss.
