Product details
Overview
TPS26632RGER from Texas Instruments is a 60V, 6A industrial eFuse with integrated 31mΩ hot-swap FET, fixed 35V overvoltage clamp, adjustable current limit (0.6–6A ±7%), output power limiting (±6%), and fast reverse current blocking (0.17µs). It protects PLC I/O modules and motor drive encoder supplies against surge (IEC 61000-4-5 Class A), short circuits, and reverse polarity.
For engineers reviewing the TPS26632RGER datasheet, TPS26632RGER pinout, TPS26632RGER application, or TPS26632RGER equivalent, key selection considerations include its VQFN-24 package, PLIM-enabled compliance with IEC 61010-1, programmable dV/dt control for inrush management, and dual fault response modes (latch-off/auto-retry) via MODE pin.
Technical Context
The TPS26632RGER implements a precision analog current monitor (IMON, ±6% gain accuracy) and a dedicated PLIM input that sets output power limit via external resistor (e.g., 100 kΩ → 100 W at 54 V). Its B_GATE/DRV interface drives an external N-channel FET for reverse polarity protection and fast reverse current blocking.
It features dual-stage overcurrent protection: fast-trip comparator (2×IOL) for hard shorts (<1 µs response) and thermal-regulated current/power limiting (129–202 ms timeout). The fixed 35-V overvoltage clamp activates during transients while maintaining Class-A system-level surge immunity per IEC 61000-4-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5 V to 60 V input range; supports 24 V and 48 V industrial rails with 67 V absolute max rating. |
| RON | 30.44 mΩ typical (25°C); enables <1.8 W conduction loss at 6 A, reducing thermal stress in compact layouts. |
| Current Limit Range | 0.6 A to 6 A adjustable via ILIM resistor (±7% tolerance); supports scalable protection across sensor, logic, and actuator loads. |
| Overvoltage Clamp | Fixed 35 V clamp (TPS26632-specific); limits downstream voltage during surges without requiring external components. |
| Power Limit Accuracy | ±6% output power limiting (PLIM); ensures precise compliance with safety standards like IEC 61010-1 energy thresholds. |
| Reverse Blocking Speed | 0.17 µs detection delay; prevents damaging reverse current flow during hot-swap or supply reversal events. |
| PGOOD Output | Active-high status signal with 1.3 ms deglitch; enables safe sequencing of downstream DC-DC converters in multi-rail systems. |
Pinout & Package
RGE package: 24-pin VQFN (4.00 mm × 4.00 mm) with exposed PowerPad™ for thermal dissipation. Pin 1 = IN, Pin 24 = PowerPad™ (must be connected to GND plane).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power input | Connects to drain of internal 31mΩ FET; accepts 4.5–60 V supply. |
| B_GATE | Blocking FET gate driver | Drives external N-FET gate for reverse polarity protection; floats if unused. |
| PLIM | Power limit programming input | Resistor-to-GND sets output power limit (e.g., 100 kΩ → 100 W); unique to TPS26632/33/35/36/37. |
| ILIM | Current limit programming input | Resistor-to-GND sets overload threshold (0.6–6 A); ±7% accuracy enables repeatable trip points. |
| MODE | Fault response selector | Open = latch-off; grounded = auto-retry; determines system recovery behavior after overcurrent. |
| IMON | Analog current monitor output | Sources 27.9 µA/A (±6%) scaled current; converts to voltage with external resistor for real-time load monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 31mΩ FET | Eliminates need for discrete hot-swap MOSFET and gate driver, reducing BOM count and layout area by >30%. |
| Adjustable dV/dt control | Capacitor on dVdT pin sets output slew rate; prevents inrush into large unknown capacitive loads (e.g., fieldbus terminations). |
| IEC 61000-4-5 Class-A surge immunity | Validated performance at 24 V supply; simplifies system-level EMC certification for industrial environments. |
| UL 2367 recognition & IEC 62368-1 certification | Meets end-equipment safety standards out-of-the-box; reduces qualification time for factory automation equipment. |
| Thermal regulation + shutdown | Regulates current above 145°C (TJ_REG) and shuts down at 165°C (TTSD) with 11°C hysteresis; prevents catastrophic failure under sustained overload. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS26633RGER | Same RGE package and 35 V clamp, but adds 2× pulse overcurrent support (vs. 1× in TPS26632). | Preferred for motor start-up or capacitor charging events requiring temporary 2× current headroom. | Select TPS26633RGER if pulsed loads exceed steady-state current limit; otherwise TPS26632RGER offers tighter cost and simpler design. |
| TPS26635RGER | Same RGE package and 2× pulse support, but uses 39 V overvoltage clamp (vs. 35 V). | Suitable for higher-voltage 48 V systems where 35 V clamp may cause nuisance tripping. | Choose TPS26635RGER for 48 V nominal rails; TPS26632RGER is optimized for 24 V/36 V systems with stricter clamp margin. |
Compared with TPS26633RGER and TPS26635RGER, the TPS26632RGER provides the most cost-effective solution for 24 V industrial systems requiring fixed 35 V clamping and single-cycle current limiting-without sacrificing accuracy, surge immunity, or thermal robustness.

FAQ
What is the overvoltage protection method used in the TPS26632RGER?
The TPS26632RGER uses a fixed 35 V overvoltage clamp-not cutoff-to limit output voltage during transients. This is confirmed in the Device Comparison Table and Electrical Characteristics section, where VOVC is specified as 32.8 V (typical) with 35 V maximum. Unlike TPS26630/31 variants, it does not implement adjustable OVP cutoff.
Does the TPS26632RGER support reverse polarity protection without external components?
No. The TPS26632RGER requires an external N-channel FET connected via B_GATE and DRV pins to provide reverse polarity protection and reverse current blocking. The datasheet explicitly states this capability is enabled "with an external N-channel FET", and the simplified schematic shows the external FET as mandatory for RCB functionality.
How is output power limiting configured on the TPS26632RGER?
Output power limiting on the TPS26632RGER is configured using a resistor from the PLIM pin to GND. For example, a 100 kΩ resistor sets a 100 W limit at 54 V input (per Electrical Characteristics table). The PLIM feature is exclusive to TPS26632, TPS26633, TPS26635, TPS26636, and TPS26637 variants.
What fault response modes does the TPS26632RGER support?
The TPS26632RGER supports two configurable fault responses via the MODE pin: open = latch-off (requires manual reset), and grounded = auto-retry (attempts recovery after ~670 ms). This is documented in the Device Functional Modes section and confirmed in the Device Comparison Table under "OVERLOAD FAULT RESPONSE".
Is the TPS26632RGER certified for safety-critical industrial use?
Yes. The TPS26632RGER is UL 2367 recognized (File No. E169910) and IEC 62368-1 certified, as stated in the Features section. These certifications validate its suitability for safety-related functions in factory automation, motor drives, and other industrial equipment requiring third-party safety approval.
