Product details
Overview
TPS26631RGET from Texas Instruments is a 60V, 6A industrial eFuse with integrated 31mΩ hot-swap FET, adjustable current limit (0.6–6A ±7%), fast reverse current blocking (0.17µs), and IEC61000-4-4/4-5 surge immunity for PLC and motor drive power path protection.
For engineers reviewing the TPS26631RGET datasheet, TPS26631RGET pinout, TPS26631RGET application, or TPS26631RGET equivalent, this page delivers verified electrical specs, thermal behavior, fault response timing, reverse polarity support via B_GATE/DRV, and precise analog current monitoring (IMON ±6%) - all critical for industrial overcurrent and surge-hardened designs.
Technical Context
The TPS26631RGET implements dual-stage overcurrent protection: fast-trip comparator (3×IOL) responds in ≤1µs to hard shorts, while active current limiting with 2× pulse support handles transient surges up to 25.5ms. Its B_GATE/DRV interface drives an external N-channel FET to enforce reverse polarity protection and sub-1µs reverse current blocking.
Thermal regulation activates at 136–154°C, with full thermal shutdown at 165°C and 11°C hysteresis. Output slew rate is programmable via dVdT capacitor (25 V/V gain), enabling controlled inrush into large capacitive loads without tripping during startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5V to 60V input range supports 24V/48V industrial rails; 67V absolute max withstand enables robust surge margin. |
| RON (IN→OUT) | 30.44 mΩ typical at 25°C - limits conduction loss to <183 mW at 6A, reducing thermal stress in continuous operation. |
| Current Limit Range | 0.6A–6A adjustable via ILIM resistor (±7% accuracy) - enables precise trip thresholds for diverse load profiles. |
| Reverse Blocking Speed | 0.17 µs detection delay - prevents backfeed damage during input reversal in systems with shared bus architectures. |
| Surge Immunity | IEC61000-4-5 Class-A compliance confirmed - sustains 24V supply-level surge events without latch-off or output collapse. |
| IMON Accuracy | ±6% gain error (27.9 µA/A typical) - enables high-fidelity real-time load current monitoring for predictive maintenance. |
| PGOOD Timing | 1.3 ms deglitch delay on falling edge - ensures stable downstream DC-DC enable signaling after valid output voltage establishment. |
Pinout & Package
RGE package: 24-pin VQFN (4.00mm × 4.00mm) with exposed PowerPad™ thermally connected to PCB ground plane for 2.8°C/W junction-to-case (bottom) resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power input | Connects to drain of internal 31mΩ FET; accepts 4.5–60V supply with 67V transient rating. |
| B_GATE | Blocking FET gate driver | Drives external N-FET gate for reverse polarity protection; clamped to 8.3–14V above IN_SYS. |
| DRV | Pulldown switch driver | Fast pulldown control for external N-FET gate; ensures rapid reverse current cutoff (<0.17µs). |
| IN_SYS | Device supply & reference | Provides bias for internal circuitry; connects to source of external blocking FET when used. |
| ILIM | Current limit programming | Resistor-to-GND sets 0.6–6A limit (±7%); 3kΩ yields 6A nominal trip point. |
| MODE | Fault response selector | Open = latch-off; grounded = auto-retry - configures behavior after overcurrent event. |
| IMON | Analog current monitor | Sources 27.9 µA/A scaled current; resistor-to-GND converts to voltage for ADC reading. |
| PGOOD | Power status flag | Active-high open-drain output asserts when OUT exceeds PGTH threshold (1.2V ±2%). |
| FLT | Fault indicator | Open-drain output pulled low during UVLO, OVP, overcurrent, thermal, or reverse fault conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable output slew rate | dVdT pin controls ramp time (e.g., 8.35 ms with 22nF cap) - eliminates inrush-induced voltage droop across system capacitance. |
| Programmable overvoltage cutoff | OVP pin sets trip threshold (33.2–35.4V rising) - disables FET before downstream components exceed safe voltage ratings. |
| Reverse polarity protection | B_GATE + DRV interface enables <1µs reverse current blocking - protects against miswired 24V/48V field connections. |
| UL 2367 recognition | File E169910 certified with RILIM ≥ 3kΩ - satisfies safety requirements for industrial equipment without additional external certification effort. |
| Thermal regulation | Activates at 136–154°C to throttle current before shutdown - maintains partial functionality during sustained overload. |
Applications
| PLC Power Distribution | Motor Drive Encoder Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS26630RGET | No pulse overcurrent support; single-cycle current limiting only. | Lacks 2× transient surge handling - unsuitable for motor start-up or solenoid actuation loads. | Select when steady-state overload protection suffices and cost optimization is prioritized over surge margin. |
| TPS26633RGER | Includes output power limiting (PLIM) and 35V fixed overvoltage clamp. | Enables IEC61010-1 compliance for measurement equipment; clamp protects downstream LDOs from overvoltage. | Choose when combined current + power limiting is required, or when fixed 35V clamp better matches system rail tolerance than adjustable OVP. |
Compared with TPS26630RGET, the TPS26631RGET adds 2× pulse overcurrent support for motor/solenoid loads, while TPS26633RGER trades adjustable OVP for fixed 35V clamping and PLIM - making TPS26631RGET optimal for general-purpose industrial surge resilience without power-limiting complexity.

FAQ
What is the maximum continuous current rating for the TPS26631RGET?
The TPS26631RGET supports continuous output current up to 6A, with RON of 30.44 mΩ typical at 25°C. At 6A, conduction loss remains below 183 mW, enabling reliable operation within thermal limits when mounted on a 2-layer PCB with adequate copper pour. Derating applies above 85°C ambient per the RθJA = 31.4°C/W specification.
Does the TPS26631RGET support reverse polarity protection without external components?
No - the TPS26631RGET requires an external N-channel MOSFET and its associated DRV pulldown switch to implement reverse polarity protection. The B_GATE pin drives the external FET's gate, while DRV actively pulls it low during reverse events. Without these components, the device provides forward-only protection and cannot block reverse current.
How does the MODE pin configure fault response on the TPS26631RGET?
The MODE pin on the TPS26631RGET selects between two overcurrent fault behaviors: open-circuit configuration latches off permanently after a fault, requiring manual reset; grounding MODE enables auto-retry mode with 550–800 ms delay between attempts. This setting directly determines system recovery strategy during transient overloads like motor startup.
What is the accuracy of the IMON current monitor output on the TPS26631RGET?
The IMON output on the TPS26631RGET has a gain accuracy of ±6% across 0.6–6A output current, with typical gain of 27.9 µA/A. At 6A, IMON sources 167.4 µA ±10 µA - sufficient for 12-bit ADC resolution with appropriate scaling resistor. Gain error remains stable over temperature (–40°C to +125°C) per Figure 6-13.
Can the TPS26631RGET be used in 48V telecom applications?
Yes - the TPS26631RGET operates from 4.5V to 60V and withstands 67V absolute maximum, making it suitable for 48V nominal telecom distribution. Its 31mΩ RON limits power loss to 900 mW at 48V/6A, and IEC61000-4-5 Class-A surge immunity meets GR-1089-CORE requirements when paired with appropriate TVS diodes on the input.
