Product details
Overview
TPS25200QDRVRQ1 from Texas Instruments is an AEC-Q100 qualified automotive-grade 5-V eFuse with precision adjustable current limit (85 mA to 2.7 A), overvoltage clamp (5.4 V ±0.15 V), and 7.6-V overvoltage lockout. It integrates a 67-mΩ high-side N-channel MOSFET, reverse current blocking, and thermal shutdown for USB port protection in vehicle infotainment systems.
For engineers reviewing the TPS25200QDRVRQ1 datasheet, TPS25200QDRVRQ1 pinout, TPS25200QDRVRQ1 application, or TPS25200QDRVRQ1 equivalent, key selection considerations include programmable current-limit accuracy (±6.3% at 2.7 A), 0.6-μs OVLO response, 3.5-μs short-circuit reaction, and WSON-6 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The TPS25200QDRVRQ1 implements dual thermal protection: OTSD1 triggers at 135°C during sustained current-limit events, while OTSD2 activates at 155°C regardless of operating mode. Its internal regulation loop sources current from the ILIM pin to set current threshold via external resistor, enabling precise load-current control across temperature.
Overvoltage handling uses three distinct modes: UVLO disables below 2.35 V, OVC clamps VOUT to 5.4 V between 5.4–7.6 V VIN, and OVLO disconnects the switch above 7.6 V with 0.6-μs delay. FAULT reporting includes 8-ms deglitching for overcurrent but no deglitching for OVLO or OTSD2 events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating VIN Range | 2.5 V to 6.5 V - supports standard 5-V USB bus with margin; tolerates up to 20 V absolute max without damage |
| Current-Limit Range | 85 mA to 2.7 A - set by single external RILIM (36 kΩ–1100 kΩ); enables design flexibility for diverse load profiles |
| Overvoltage Clamp | 5.25 V to 5.55 V - precision-regulated output clamp protects downstream 5-V ICs during transient overvoltage |
| rDS(on) | 67 mΩ (typ) - low conduction loss enables 2.4 A continuous operation with minimal thermal rise |
| OVLO Threshold | 6.8 V to 8.45 V - shuts off switch before input transients damage load; hysteresis prevents chatter near threshold |
| FAULT Response Time | 3.5 μs (short-circuit), 0.6 μs (OVLO) - fast isolation prevents fault propagation in safety-critical automotive nodes |
| Thermal Shutdown | 135°C (OTSD1), 155°C (OTSD2) - dual-sensor architecture ensures robust protection under varying fault conditions |
Pinout & Package
TPS25200QDRVRQ1 uses a 2.00 mm × 2.00 mm WSON-6 package with exposed thermal pad (DRV variant). The thermal pad must be externally connected to GND for optimal heat dissipation and electrical reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Protected power output | Delivers regulated 5-V supply to load; clamped to 5.4 V during overvoltage; includes 480-Ω discharge path when disabled |
| EN (Pin 4) | Logic-level enable input | Active-high TTL/CMOS-compatible control; requires external pullup ≤300 kΩ to avoid exceeding 7-V absolute max rating |
| FAULT (Pin 3) | Open-drain fault indicator | Asserts low during overcurrent, overtemperature, or OVLO; requires external pullup to host I/O rail (≤6.5 V) |
| IN (Pin 6) | Input voltage supply | Accepts 2.5–6.5 V nominal; withstands 20 V DC; connects to 0.1-μF ceramic bypass capacitor placed adjacent to pin |
| ILIM (Pin 2) | Current-limit programming node | Sources current proportional to desired IOS; connects to ground via precision resistor (36–1100 kΩ) |
| GND (Pin 5) | Ground reference | Primary return path; internally tied to exposed thermal pad; must be externally soldered to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Precision overvoltage clamp | 5.4 V ±0.15 V output regulation during 5.4–7.6 V input transients - eliminates need for external Zener or TVS diodes |
| Programmable current limit | 85 mA–2.7 A range with ±6.3% accuracy at 2.7 A - enables optimized power delivery without overdesigning upstream supplies |
| Reverse current blocking | Prevents back-drive from active loads when disabled - avoids undefined states in hot-plug USB slave devices |
| Dual thermal sensing | Independent OTSD1 (135°C) and OTSD2 (155°C) sensors - provides layered protection against both sustained overload and catastrophic failure |
| Fast fault response | 3.5-μs short-circuit detection and 0.6-μs OVLO shutdown - limits energy delivered during faults to safe levels per ISO 16750-2 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2553DRVR | Non-automotive grade; lacks AEC-Q100 qualification and OTSD2 thermal sensor; same pinout and basic functionality | Intended for industrial/commercial USB hubs; not validated for automotive temperature cycling or ESD stress | Select only for non-automotive designs where cost is prioritized over automotive reliability certification |
| TPS259211RGER | Higher 2.7-A fixed current limit; includes true current monitoring output (IMON); 32-V absolute max VIN; different pinout | Used in advanced ADAS domain controllers requiring real-time current telemetry and wider input range | Choose when IMON feedback or >20-V transient tolerance is required; requires PCB redesign due to 20-pin VQFN package |
Compared with TPS25200QDRVRQ1, TPS2553DRVR offers identical footprint and basic protection but omits automotive qualification and dual thermal sensing, while TPS259211RGER adds current monitoring and higher voltage tolerance at the cost of pinout incompatibility and increased complexity.

FAQ
What is the maximum continuous output current supported by the TPS25200QDRVRQ1?
The TPS25200QDRVRQ1 supports up to 2.4 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN = 2.5–6.5 V). This rating assumes proper PCB thermal design using the exposed thermal pad. At higher ambient temperatures or with insufficient copper area, derating applies per the RθJB = 36.1°C/W thermal metric.
How does the TPS25200QDRVRQ1 respond to an input voltage transient exceeding 7.6 V?
When VIN exceeds 7.6 V, the TPS25200QDRVRQ1 enters overvoltage lockout (OVLO) mode within 0.6 μs and disconnects the internal MOSFET, isolating OUT from IN. The FAULT pin asserts low immediately. The device remains latched off until VIN drops below the OVLO hysteresis threshold (~7.53 V), at which point it resumes normal operation if EN is high.
Can the TPS25200QDRVRQ1 be used without an external current-limit resistor?
No. The TPS25200QDRVRQ1 requires an external resistor (RILIM) connected between ILIM and GND to set the current-limit threshold. Without RILIM, the device defaults to an undefined current limit and may not operate reliably. The datasheet specifies a valid range of 36 kΩ to 1100 kΩ for stable regulation and accuracy.
Does the TPS25200QDRVRQ1 provide reverse current blocking during normal operation?
Yes. The TPS25200QDRVRQ1 blocks reverse current flow from OUT to IN whenever the device is disabled (EN = low) or in UVLO/OVLO states. This prevents back-driving of the source by active loads, ensuring defined power sequencing in multi-rail automotive systems. Reverse leakage is specified at 5 µA max at 25°C.
What is the purpose of the thermal pad on the TPS25200QDRVRQ1 WSON package?
The exposed thermal pad on the TPS25200QDRVRQ1 serves two critical functions: it provides the primary thermal path from the die to the PCB (RθJB = 36.1°C/W), and it is electrically connected to GND internally. It must be soldered to a dedicated GND copper pour on the PCB to ensure both thermal performance and correct electrical reference for the device's ground-return paths.
