Product details
Overview
TPS26630RGET from Texas Instruments is a 60V, 6A industrial eFuse with integrated 31mΩ hot-swap FET, adjustable 0.6–6A current limiting (±7%), fast reverse current blocking (0.17µs), and IEC61000-4-4/4-5 surge immunity. It delivers power path protection in PLC I/O modules and motor drive encoder supplies.
For engineers reviewing the TPS26630RGET datasheet, TPS26630RGET pinout, TPS26630RGET application, or TPS26630RGET equivalent, key selection criteria include its 67V absolute maximum input rating, programmable UVLO/OVP thresholds, PGOOD output for DC-DC enable control, and MODE-selectable auto-retry vs latch-off fault response.
Technical Context
The TPS26630RGET implements a precision current-limiting architecture with fast-trip comparator (2×IOL) and thermal regulation at 136–154°C. Its B-GATE driver supports external N-FET reverse polarity protection, while dV/dT control enables inrush management via external capacitor.
It features dual-stage overvoltage protection: programmable cutoff (adjustable threshold) and robust system-level surge handling per IEC61000-4-5 at 24V supply. The analog IMON output provides ±6% accurate current monitoring, and PGOOD asserts only after VPGTH exceeds 1.2V with deglitch timing of 1.07–1.6ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 60V operating; 67V absolute max - supports wide industrial rail voltages including 24V and 48V systems. |
| RON (IN to OUT) | 26–34.5 mΩ at 25°C - minimizes conduction loss and thermal rise under 6A continuous load. |
| Current Limit Range | 0.6A to 6A adjustable via ILIM resistor (±7%) - enables precise overload protection across diverse load profiles. |
| Reverse Current Blocking | 0.17 µs detection delay - prevents backfeed during input brownout or hot-swap events in redundant power architectures. |
| Surge Immunity | IEC61000-4-5 compliant with Class-A performance - sustains 24V supply surges without latch-off or damage. |
| PGOOD Output | Active-high with 1.07–1.6ms deglitch - enables safe sequencing of downstream DC-DC converters after stable output ramp. |
| Thermal Regulation | 136–154°C setpoint with 2.3–2.9s timeout - maintains safe operation during sustained overload without immediate shutdown. |
Pinout & Package
RGE package: 24-pin VQFN (4.00mm × 4.00mm) with exposed PowerPad™ thermal pad connected to GND. Pin 1 = IN, Pin 24 = PowerPad™.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power input | Connects to drain of internal 31mΩ FET; accepts 4.5–60V supply. |
| B_GATE | Blocking FET gate driver | Drives external N-FET gate for reverse polarity protection; floats if unused. |
| IN_SYS | Device supply & input reference | Provides bias for internal circuitry; tied to IN when no external FET is used. |
| UVLO / OVP | Programmable threshold inputs | Resistor-divider sets undervoltage lockout (15.1–15.9V) or overvoltage cutoff (33.2–35.4V). |
| ILIM | Current limit programming | Resistor to GND sets 0.6–6A limit; tolerance ±7% over temperature. |
| MODE | Fault response selector | Open = latch-off; grounded = auto-retry - determines recovery behavior after overcurrent event. |
| PGOOD | Power status indicator | Active-high open-drain output signals valid output voltage after PGTH threshold crossing. |
| IMON | Analog current monitor | Sources 27.9 µA/A (±6%) scaled current; converts to voltage with external resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 60V, 31mΩ FET | Eliminates discrete MOSFET and gate driver, reducing BOM count and layout area in space-constrained industrial modules. |
| Adjustable output slew rate | dV/dT pin controls output ramp time (e.g., 8.35ms with 22nF cap) to prevent inrush-induced voltage droop on large capacitive loads. |
| Fast reverse current blocking | 0.17µs response blocks backfeed before energy transfer occurs - critical for hot-swap redundancy and battery backup systems. |
| UL 2367 & IEC 62368-1 certified | Meets safety standards for industrial equipment without requiring additional certification effort from end-equipment designers. |
| Electrical fast transients immunity | IEC61000-4-4 level 4 compliance ensures reliable operation in electrically noisy factory automation environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS26631RGET | Same RGE package; adds 2× pulse overcurrent support and identical UVLO/OVP cutoff architecture. | Preferred where brief inrush surges exceed steady-state limit but require continued operation (e.g., solenoid actuation). | Select TPS26631RGET if pulse-current tolerance is required; otherwise TPS26630RGET offers simpler fault response. |
| TPS26632RGET | Replaces OVP cutoff with 35V fixed overvoltage clamp; adds adjustable output power limiting (±6%). | Required for IEC61010-1 compliance where clamping-not cutoff-is mandated for overvoltage protection. | Choose TPS26632RGET only when power limiting and clamping are mandatory; TPS26630RGET retains full cutoff flexibility. |
Compared with TPS26631RGET and TPS26632RGET, the TPS26630RGET provides the most flexible programmable OVP/UVLO thresholds and simplest latch-off fault behavior-ideal for deterministic protection in safety-critical I/O modules where auto-retry is undesirable.

FAQ
What is the absolute maximum input voltage rating for the TPS26630RGET?
The TPS26630RGET has an absolute maximum input voltage rating of 67V on the IN_SYS pin for continuous operation, and 75V for 10ms transients at TA = 25°C. Exceeding these ratings may cause permanent damage. The recommended operating range remains 4.5V to 60V, aligning with standard industrial 24V and 48V rails. Always observe derating guidelines in the thermal section when operating near limits.
How does the TPS26630RGET implement reverse polarity protection?
The TPS26630RGET supports reverse polarity protection using its B_GATE and DRV pins to drive an external N-channel FET. When reverse voltage is detected (VIN_SYS – VOUT < –9 mV), the device asserts DRV within 0.17 µs to pull down the external FET's gate, blocking reverse current. No internal reverse-blocking FET is present-the function requires external components and is disabled if B_GATE and DRV are left floating.
Can the TPS26630RGET be used without an external blocking FET?
Yes, the TPS26630RGET operates fully without an external blocking FET. In that configuration, IN_SYS is shorted to IN, and B_GATE/DRV pins are left floating. Reverse polarity protection is then disabled, but all other functions-including current limiting, surge immunity, UVLO/OVP, PGOOD, and IMON-remain active and operational per datasheet specifications.
What is the purpose of the MODE pin on the TPS26630RGET?
The MODE pin configures the TPS26630RGET's overcurrent fault response: open circuit selects latch-off (requires SHDN toggle or power cycle to reset), while grounding selects auto-retry (attempts restart after ~1ms delay). This selection directly affects system reliability strategy-latch-off prevents repeated fault cycling in persistent shorts, whereas auto-retry suits intermittent overload conditions like motor startup.
Does the TPS26630RGET provide output power limiting functionality?
No, the TPS26630RGET does not support output power limiting (PLIM). That feature is exclusive to variants TPS26632, TPS26633, TPS26635, TPS26636, and TPS26637. The TPS26630RGET implements only adjustable current limiting (via ILIM) and programmable overvoltage cutoff (via OVP), with no PLIM pin or associated circuitry. Use TPS26632RGET if power-based limiting is required.
