Product details
Overview
TPS16630RGET from Texas Instruments is a 60V, 6A industrial eFuse with integrated 31mΩ hot-swap FET, adjustable current limit (0.6–6A ±7%), and programmable output slew rate control via dVdT pin. It provides overcurrent, UVLO, and OVP protection with ±2% threshold accuracy, low 21µA shutdown quiescent current, and PGOOD output - deployed in PLC I/O modules and factory automation power rails.
For engineers reviewing the TPS16630RGET datasheet, TPS16630RGET pinout, TPS16630RGET application, or TPS16630RGET equivalent, key selection criteria include its 4.5–60V operating range, thermal regulation during inrush, latch/auto-retry fault response, and VQFN-24 package compatibility with industrial thermal requirements.
Technical Context
The TPS16630RGET implements a precision current-limiting architecture with fast-trip comparator (1µs response) and thermal regulation loop that maintains junction temperature at 145°C (typ.) during capacitive load charging. Its gate control logic integrates POR, UVLO, and SHDN-driven enable/disable sequencing with deglitched FLT assertion.
Unlike TPS16632/TPS16637, the TPS16630RGET lacks output power limiting (PLIM) functionality and fixed 39V overvoltage clamp; instead it supports adjustable OVP cutoff (via OVP pin) and uses ILIM for current setting only - confirmed by Device Comparison Table and Pin Functions table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5V to 60V input range - supports wide industrial DC bus voltages including 24V, 48V, and 60V SELV systems. |
| Current Limit Range | 0.6A to 6A (±7%) - set by resistor on ILIM pin; enables precise overload sizing without overdesign of upstream supply. |
| RON | 30.44mΩ typical at 25°C - minimizes conduction loss (≤1.1W at 6A), critical for thermal management in compact 4×4mm VQFN. |
| Shutdown Quiescent Current | 21µA - allows long-term system standby without battery drain in always-on industrial controllers. |
| UVLO/OVP Accuracy | ±2% threshold tolerance - eliminates need for external supervisor IC in brown-out and overvoltage monitoring. |
| Thermal Regulation Set Point | 145°C typical - actively throttles inrush current to prevent thermal runaway when charging large output capacitance. |
| Fast-Trip Response | 1µs - isolates short-circuit faults before PCB trace damage or connector arcing occurs. |
Pinout & Package
TPS16630RGET is housed in a thermally enhanced 24-pin VQFN package (4.00mm × 4.00mm) with exposed PowerPAD™ for PCB-level heat sinking. The package supports –40°C to +125°C operation and requires GND connection to PowerPAD™ per TI layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN / P_IN | Power input / device supply | Connects directly to source rail; powers internal circuitry and drives FET gate - must be tied together externally. |
| OUT | Protected output | Delivers regulated, fault-protected power to downstream load; voltage slew rate controlled via dVdT pin. |
| ILIM | Current limit programming | Resistor-to-GND sets trip point (0.6–6A); analog input with ±7% accuracy across temperature. |
| dVdT | Output ramp control | Capacitor-to-GND sets output slew rate; floating enables fastest startup (24V/500µs); enables hot-plug compliance. |
| SHDN | Enable/disable control | Active-high logic input; pulls internal FET OFF and enters 21µA shutdown mode - used for MCU-controlled power sequencing. |
| PGOOD | Power status indicator | Open-drain active-high signal confirms FET enhancement; used to enable downstream DC/DC converters synchronously. |
| FLT | Fault event flag | Open-drain active-low output asserts on UVLO, OVP, overcurrent, or thermal fault - debounced for noise immunity. |
| IMON | Analog current monitor | Sources 27.9µA/A (±6%) proportional current - converts to voltage with external resistor for real-time load health monitoring. |
| UVLO / OVP | Protection threshold inputs | Resistor-divider inputs set undervoltage lockout and overvoltage cutoff thresholds (±2% accuracy); no PLIM or clamp function. |
| MODE | Fault response selection | Open = latch-off; grounded = auto-retry - configures behavior after current-limit fault without firmware intervention. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 31mΩ FET | Eliminates external MOSFET and gate driver, reducing BOM count and layout area in space-constrained I/O modules. |
| Adjustable slew rate control | Prevents backplane voltage sag and EMI during hot insertion of field modules - critical for modular PLC chassis. |
| Thermal regulation loop | Automatically limits inrush current to maintain 145°C junction temperature, enabling safe charge of >1000µF output capacitance. |
| Deglitched fault reporting | Filters transient noise on UVLO/OVP lines to avoid false trips in electrically noisy factory environments. |
| UL 2367 & IEC 62368-1 certified | Meets safety standards for industrial end equipment without requiring additional isolation or certification effort. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS26630RGET | Same 60V/6A rating and VQFN-24 package; adds integrated reverse polarity protection and higher 75V abs max rating. | Required where input reverse voltage risk exists (e.g., battery backup systems); not needed for standard forward-biased industrial rails. | Select TPS26630RGET if reverse polarity protection is mandatory; otherwise TPS16630RGET offers lower cost and identical core protection features. |
| TPS25982LARVRR | 40V max, 8A rating, WQFN-32 package; includes PMBus interface and black-box fault logging not present in TPS16630RGET. | Suitable for digitally managed server or telecom power systems needing telemetry; incompatible with 60V industrial buses. | Choose TPS25982LARVRR only when digital configuration and fault history are required; TPS16630RGET remains optimal for analog-programmed 60V industrial use cases. |
Compared with TPS26630RGET and TPS25982LARVRR, the TPS16630RGET delivers the most cost-effective, pin-compatible solution for analog-configured 60V industrial eFuse applications - retaining full thermal regulation, fast-trip response, and UL/IEC certification without added complexity or voltage derating.

FAQ
What is the absolute maximum input voltage rating for the TPS16630RGET?
The TPS16630RGET has an absolute maximum input voltage rating of 67V across IN and P_IN pins, with a 75V rating for 10ms transients at 25°C. This exceeds its 60V operating range to accommodate industrial supply surges and transient events without damage, as specified in Section 6.1 Absolute Maximum Ratings.
Does the TPS16630RGET support output power limiting (PLIM) functionality?
No, the TPS16630RGET does not support output power limiting. Per the Device Comparison Table and Pin Functions documentation, PLIM is exclusive to TPS16632 and TPS16637 variants. The TPS16630RGET provides only adjustable current limiting via ILIM and overvoltage cutoff via OVP pin.
How is the current limit threshold set on the TPS16630RGET?
The current limit threshold on the TPS16630RGET is set using a resistor connected between the ILIM pin and GND. Resistance values from 3kΩ to 30kΩ yield current limits from 6A down to 0.6A, with ±7% accuracy across temperature - verified in Electrical Characteristics Table 6.5 and Figure 6-5.
What thermal performance can be expected from the TPS16630RGET in its VQFN package?
The TPS16630RGET in RGE (VQFN-24) package has a junction-to-ambient thermal resistance (RθJA) of 31.4°C/W and junction-to-board (RθJB) of 10.2°C/W. With proper PCB copper pour under the PowerPAD™, it sustains 6A continuous current at +85°C ambient - validated in Thermal Information Table 6.4 and Figure 6-1.
Can the TPS16630RGET be used in systems requiring UL 2367 recognition?
Yes, the TPS16630RGET is UL 2367 recognized (File No. E169910), with RILIM ≥ 3kΩ per safety certification requirements. This enables direct use in industrial end equipment requiring recognized component status without additional system-level evaluation.
