Product details
Overview
TPS16630RGER from Texas Instruments is a 60V, 6A industrial eFuse with integrated 31mΩ hot-swap FET, adjustable current limit (0.6–6A ±7%), and programmable undervoltage lockout/overvoltage cutoff. It delivers precise inrush control via dVdT pin, thermal regulation during power-up, and fault signaling via open-drain FLT and active-high PGOOD - deployed in PLC I/O modules, motor drive encoder supplies, and telecom radio power rails.
For engineers reviewing the TPS16630RGER datasheet, TPS16630RGER pinout, TPS16630RGER application, or TPS16630RGER equivalent, key selection criteria include its 4.5–60V operating range, ±2% UVLO/OVP threshold accuracy, 21µA shutdown quiescent current, and VQFN-24 package compatibility with industrial thermal and layout constraints.
Technical Context
The TPS16630RGER implements a precision current-limiting architecture with dual-stage overcurrent protection: fast-trip comparator (45A threshold, 1µs response) for short circuits and programmable overload limit (0.6–6A) with ±7% accuracy. Its gate control logic integrates thermal regulation at 145°C (typical), automatically throttling output slew rate to maintain junction temperature within safe limits during capacitive load charging.
It features independent analog monitoring paths: IMON provides ±6% accurate current sensing (27.9 µA/A gain), while UVLO and OVP inputs accept resistor-divider networks for ±2% threshold setting. Unlike TPS16632/TPS16637, it lacks PLIM functionality but supports adjustable overvoltage cutoff (not clamp) and fixed 39V max clamp only on other variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5V to 60V input range; enables direct use with 24V/48V industrial DC supplies and SELV-compliant systems. |
| Current Limit Range | 0.6A to 6A (±7%); set by ILIM-to-GND resistor; allows precise coordination with downstream fuse ratings and PCB trace ampacity. |
| RON | 30.44 mΩ typical (25°C); minimizes conduction loss (≤1.1W at 6A), reducing thermal stress in compact industrial enclosures. |
| Shutdown Quiescent Current | 21 µA; enables low-power system standby without compromising protection readiness. |
| UVLO/OVP Accuracy | ±2% threshold tolerance; eliminates need for external supervisor IC in brown-out and overvoltage detection. |
| Thermal Regulation Setpoint | 145°C typical; actively modulates output ramp during hot-plug to prevent thermal runaway with large COUT. |
| Fast-Trip Response | 1 µs; isolates shorted loads before wiring or connector damage occurs in high-energy industrial buses. |
Pinout & Package
TPS16630RGER is housed in a 4mm × 4mm, 24-pin VQFN (RGE) package with exposed PowerPAD™ thermally connected to PCB ground plane. Pin count and layout match TI's standard RGE footprint for mechanical and thermal interoperability across the TPS1663x family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN / P_IN | Power input & device supply | Must be shorted externally; connects to internal FET drain and powers bias circuitry - requires low-inductance path to source. |
| OUT | Protected output | Source of regulated, current-limited power to load; routed with wide copper to handle up to 6A continuous. |
| ILIM | Current limit programming | Analog input accepting 3–30kΩ resistor to GND; sets trip point with ±7% accuracy across temperature. |
| dVdT | Output slew rate control | Capacitor-to-GND here defines voltage ramp time; floating enables fastest startup (24V/500µs); critical for EMI-controlled hot-plug. |
| UVLO / OVP | Threshold programming inputs | Resistor dividers set undervoltage lockout and overvoltage cutoff points; ±2% accuracy ensures tight bus supervision. |
| SHDN | Enable/disable control | Active-high logic input; pulls internal FET gate low when <0.8V; resets latched faults when cycled. |
| PGOOD | Power status indicator | Open-drain, active-high signal asserting when FET is fully enhanced; used to enable downstream DC/DC converters. |
| FLT | Fault event flag | Open-drain, active-low output asserted on UVLO, OVP, overcurrent, or thermal fault; debounced for noise immunity. |
| IMON | Analog current monitor | Current-source output (27.9 µA/A typical); converts load current to voltage via external resistor for health monitoring. |
| MODE | Fault response selection | Open = latch-off; grounded = auto-retry; determines system recovery behavior after sustained overload. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 60V, 31mΩ FET | Eliminates external MOSFET and gate driver, reducing BOM count and layout area in space-constrained I/O modules. |
| Adjustable output slew rate | Configurable inrush control prevents backplane voltage sag and avoids false resets during hot-plug insertion. |
| Thermal regulation loop | Automatically throttles output during high-power startup to hold junction at 145°C, enabling reliable charge of >1000µF loads. |
| ±6% analog current monitor (IMON) | Enables real-time load diagnostics and predictive maintenance without adding shunt resistors or amplifiers. |
| 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 |
|---|---|---|---|
| TPS26631RGER | 48V max rating, 4.5A limit, no PLIM, same 24-pin VQFN; lower RON (22mΩ), higher IQ (100µA in operation). | Suitable for 24V/48V systems where 60V headroom is unnecessary; lacks thermal regulation loop and fast-trip comparator. | Select when operating voltage ≤48V and simplified protection suffices; avoid for 60V SELV compliance or aggressive inrush control. |
| MAX17613ATG+T | 60V, 6A, 35mΩ RON, ±8% current limit, 40µA shutdown IQ; uses 16-pin TQFN; includes power limiting but no dVdT control. | Targets space-constrained designs; lacks slew-rate programmability and thermal regulation, relying on fixed foldback. | Prefer for minimal footprint where dVdT-based inrush tuning isn't required; verify IMON accuracy (±10%) if load monitoring is critical. |
Compared with TPS16630RGER, TPS26631RGER trades 60V capability and thermal regulation for lower conduction loss and simpler control, while MAX17613ATG+T offers smaller package size at the cost of programmable slew rate and tighter current limit accuracy.

FAQ
What is the maximum input voltage rating for the TPS16630RGER?
The TPS16630RGER has an absolute maximum input voltage rating of 67V, with recommended operating range from 4.5V to 60V DC. This 60V operational ceiling enables direct integration into industrial 48V and 60V SELV power systems while maintaining margin against transient overvoltages. Exceeding 67V risks permanent damage per Absolute Maximum Ratings.
Does the TPS16630RGER support adjustable output power limiting (PLIM)?
No, the TPS16630RGER does not support adjustable output power limiting. PLIM functionality is exclusive to TPS16632 and TPS16637 variants. The TPS16630RGER provides adjustable current limiting (0.6–6A), overvoltage cutoff, and undervoltage lockout - but lacks the PLIM pin and associated internal power-limit amplifier circuitry found in those variants.
How is the current limit set on the TPS16630RGER?
The current limit on the TPS16630RGER is set by connecting a resistor between the ILIM pin and GND. Values from 3kΩ to 30kΩ yield limits from 6A to 0.6A respectively, with ±7% accuracy across –40°C to +125°C. For example, a 4.02kΩ resistor sets ~4.5A limit. The relationship is linear and documented in the Electrical Characteristics table of the datasheet.
What package type is used for the TPS16630RGER?
The TPS16630RGER uses a 4mm × 4mm, 24-pin VQFN package (RGE suffix), with an exposed PowerPAD™ thermally connected to PCB ground. This package is distinct from the HTSSOP-20 option offered for other TPS1663x variants and provides superior thermal performance (RθJA = 31.4°C/W) for high-current industrial applications.
Can the TPS16630RGER be used in functional safety–compliant systems?
Yes, the TPS16630RGER is functional safety-capable: TI provides documentation including FIT rate data, failure mode analysis, and safety manual guidance to support IEC 61508 and ISO 13849 system-level certification. While the device itself is not ASIL-certified, its diagnostic coverage and predictable fault responses make it suitable for use in safety-related subsystems under architect-level validation.
