Product details
Overview
TPS26632RGET 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%), analog current monitor (±6%), and power-good output. It provides reverse polarity protection via external N-FET control and fast reverse-current blocking (0.17µs), deployed in PLC I/O modules and motor drive encoder supplies.
For engineers reviewing the TPS26632RGET datasheet, TPS26632RGET pinout, TPS26632RGET application, or TPS26632RGET equivalent, key selection criteria include its 35V fixed OV clamp, programmable output power limiting (±6%), B-GATE/DRV dual gate driver for reverse protection, thermal regulation at 145°C, and VQFN-24 package with PowerPad™ for thermal management.
Technical Context
The TPS26632RGET implements a precision current-limiting architecture with fast-trip comparator (2×IOL) and soft-short response (2.2–4.5µs), coupled with programmable output power limiting (PLIM) that enforces compliance with IEC 61010-1 and UL 1310 standards. Its B-GATE/DRV dual-output gate driver enables active reverse-current blocking using an external N-channel FET.
It features robust surge immunity per IEC 61000-4-4 and IEC 61000-4-5 Class-A system performance, with dV/dT-controlled output slew rate, adjustable UVLO/OVP thresholds, and selectable fault response (latch-off or auto-retry via MODE pin). Thermal shutdown triggers at 165°C with 11°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5V to 60V input range; supports 67V absolute max transient - enables use in 24V/48V industrial rails with surge margin. |
| RON (Total) | 26–34.5 mΩ at 25°C - minimizes conduction loss and self-heating under 6A continuous load. |
| Current Limit Range | 0.6A to 6A ±7% via ILIM resistor - allows precise overload protection tuning across diverse loads. |
| Overvoltage Clamp | Fixed 35V max (TPS26632-specific) - clamps transients without external components, simplifying design vs adjustable OVP variants. |
| Output Power Limit | Adjustable 94–160W ±6% via PLIM resistor - enforces safe power delivery during fault conditions per safety standards. |
| Reverse Current Blocking | 0.17µs detection delay - prevents backfeed damage in redundant supply or hot-swap systems. |
| Thermal Regulation | Activates at 136–154°C junction temperature - sustains operation under overload without immediate shutdown. |
Pinout & Package
TPS26632RGET uses a 24-pin VQFN (RGE) package measuring 4.00mm × 4.00mm with exposed PowerPad™ thermally connected to PCB ground plane. The PowerPad must be soldered for effective heat dissipation; it is not an electrical GND connection alone.
| 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; floats if unused. |
| DRV | Pulldown switch driver | Controls external pulldown switch for fast reverse-current blocking; floats if unused. |
| IN_SYS | Device supply & input reference | Provides bias for internal circuitry; connects to source of external blocking FET when used. |
| PLIM | Power limit programming input | Resistor-to-GND sets output power limit (94–160W); tied to GND to disable feature. |
| ILIM | Current limit programming input | Resistor-to-GND sets overload threshold (0.6–6A); determines trip point accuracy and timing. |
| MODE | Fault response selector | Open = latch-off; grounded = auto-retry - configures behavior after overcurrent event. |
| IMON | Analog current monitor output | Sources 25.66–30.14 µA/A scaled current; converts to voltage with external resistor for real-time monitoring. |
| PGOOD | Power status indicator | Active-high open-drain output signaling valid output voltage; used to enable downstream DC-DC converters. |
| FLT | Fault flag output | Open-drain active-low signal indicating UVLO, OV, thermal, or overcurrent fault condition. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 31mΩ FET | Reduces board space and BOM count vs discrete hot-swap solutions; enables compact 6A power path designs. |
| Programmable output power limiting | Enables compliance with IEC 61010-1 energy-limited circuits by capping delivered power independent of voltage or current alone. |
| Fast reverse current blocking (0.17µs) | Prevents destructive backfeed in dual-supply or battery-backup systems before downstream protection reacts. |
| IEC 61000-4-5 Class-A surge immunity | Validated for 24V supply surge testing - eliminates need for external TVS or MOV in many industrial applications. |
| Thermal regulation with timeout | Maintains regulated current during overload up to 2.54s before thermal shutdown - avoids nuisance trips during brief transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS26633RGET | Same RGE package; adds 2× pulse overcurrent support and same 35V clamp + PLIM. | Required where transient overloads (e.g., motor startup inrush) exceed steady-state limits. | Select TPS26633RGET if pulse current handling beyond 6A is needed; otherwise TPS26632RGET suffices for steady-state protection. |
| TPS26635RGET | Same RGE package; features 39V fixed overvoltage clamp instead of 35V; retains PLIM and 2× pulse support. | Suitable for higher-voltage 36V nominal systems where 35V clamp would trigger unnecessarily. | Choose TPS26635RGET only when system operating voltage exceeds 35V but remains below 39V; otherwise TPS26632RGET offers tighter clamp margin. |
Compared with TPS26633RGET and TPS26635RGET, the TPS26632RGET provides optimal balance of cost, thermal performance, and protection specificity for 24V/48V industrial systems requiring fixed 35V clamping and steady-state current limiting without pulse-overcurrent capability.

FAQ
What is the overvoltage protection method implemented in the TPS26632RGET?
The TPS26632RGET uses a fixed 35V overvoltage clamp - not adjustable cutoff - meaning it actively limits output voltage to ≤35V during overvoltage events without disconnecting the load. This is confirmed in the Device Comparison Table and Electrical Characteristics section (VOVC = 32–35V), distinguishing it from TPS26630/31 which use adjustable OVP cutoff.
Does the TPS26632RGET support reverse polarity protection without external components?
No. The TPS26632RGET requires an external N-channel FET and associated DRV/B_GATE connections to implement 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 mandatory external components for RCB functionality.
How is output power limiting configured on the TPS26632RGET?
Output power limiting on the TPS26632RGET is configured using a resistor from the PLIM pin to GND. Values between 60.4kΩ and 150kΩ set the maximum output power from 94W to 160W (±6%). Connecting PLIM directly to GND disables the feature. This is exclusive to TPS26632 and other PLIM-enabled variants per Table 5-1 and Section 6.5.
What thermal protection mechanisms does the TPS26632RGET provide?
The TPS26632RGET provides two-tier thermal protection: thermal regulation activates at 136–154°C to limit power and sustain operation, while hard thermal shutdown triggers at 165°C with 11°C hysteresis. Both are specified in Section 6.5 and validated across temperature ranges, ensuring reliable operation under overload without premature failure.
Can the TPS26632RGET be used in 48V telecom applications?
Yes - the TPS26632RGET supports 4.5–60V operation with 67V absolute maximum rating and IEC 61000-4-5 surge immunity, making it suitable for 48V telecom power distribution. However, its 35V overvoltage clamp means it will activate during normal 48V transients exceeding 35V; verify system surge profile compatibility or consider TPS26635RGET (39V clamp) for higher-margin 48V use.
