Product details
Overview
TPS16630PWPR from Texas Instruments is a 60V, 6A industrial eFuse with integrated 31mΩ hot-swap FET, adjustable current limit (0.6–6A ±7%), and programmable UVLO/OVP cutoff. It delivers precise inrush control via dVdT pin, thermal regulation during capacitive load charging, and PGOOD signaling - deployed in PLC I/O modules, motor drive encoder supplies, and telecom radio power rails.
For engineers reviewing the TPS16630PWPR datasheet, TPS16630PWPR pinout, TPS16630PWPR application, or TPS16630PWPR equivalent, this page provides verified functional context, validated pin roles for the 20-pin HTSSOP package, confirmed protection thresholds, and real-world implementation constraints including thermal regulation timeout (1.25s) and fast-trip response (1µs).
Technical Context
The TPS16630PWPR implements dual-stage overcurrent protection: fast-trip comparator (45A threshold) for sub-µs short-circuit isolation 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 large-capacitance power-up.
UVLO and OVP are independently adjustable via resistor dividers on UVLO and OVP pins, each with ±2% threshold accuracy and dedicated fault timing (UVLO turnoff delay: 9–16µs; OVP turnoff delay: 8.5–14µs). Unlike TPS16632/TPS16637, the TPS16630 lacks PLIM functionality and uses OVP cutoff-not clamp-making it suitable for systems requiring full shutdown on overvoltage rather than clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5V to 60V input range; absolute max 67V - supports industrial 48V DC systems with margin for transients. |
| RON | 30.44 mΩ typical (25°C), ≤53 mΩ across –40°C to +125°C - enables <1.8W conduction loss at 6A, reducing heatsink requirements. |
| Current Limit Accuracy | ±7% over 0.6–6A range - minimizes overdesign of upstream power supplies while ensuring reliable trip margins. |
| Quiescent Current | 21 µA in shutdown - enables always-on monitoring without battery drain in low-power industrial nodes. |
| Fast-Trip Response | 1 µs detection of >45A short-circuit - isolates faults before PCB trace fusing or connector arcing occurs. |
| Thermal Regulation Setpoint | 145°C typical (136–154°C range) - dynamically controls dV/dt to prevent thermal runaway during hot-plug into 1000µF+ loads. |
| PGOOD Delay | 8–13 ms deglitched assertion - ensures stable output before enabling downstream DC/DC converters. |
Pinout & Package
TPS16630PWPR is housed in a 20-pin HTSSOP package (6.50mm × 4.40mm) with exposed PowerPAD™ thermally connected to GND. Pin 1 is top-left corner (marking dot adjacent), and PowerPAD™ must be soldered to a thermal pad for junction-to-board RθJB = 10°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 1, 2, 4, 5) | Power input | Connects to DRAIN of internal 60V FET; multiple pins reduce IR drop and improve thermal spreading. |
| P_IN (Pin 6) | Device supply rail | Must be tied directly to IN; powers internal bias circuitry and gate driver - not a separate supply. |
| OUT (Pins 17, 18) | Protected output | SOURCE of internal FET; dual pins handle 6A continuous with low inductance path to load. |
| SHDN (Pin 13) | Enable/disable control | Pull low to enter 21µA shutdown; rising edge above 2V resets latched faults - enables MCU-controlled power sequencing. |
| ILIM (Pin 11) | Overload threshold set | Resistor to GND sets current limit (3kΩ → 6A; 30kΩ → 0.6A); ±7% accuracy enables precise trip calibration. |
| dVdT (Pin 10) | Output slew rate control | Capacitor to GND sets ramp time (22nF → 8.35ms); floating enables fastest charge (350–700µs) with thermal regulation fallback. |
| UVLO (Pin 7) | Undervoltage lockout input | Resistor divider sets turn-on threshold (1.2V ±2%); falling edge below 1.122V asserts FLT and disables FET. |
| OVP (Pin 8) | Overvoltage protection input | Resistor divider sets cutoff threshold (1.2V ±2%); rising edge above 1.224V disables FET and asserts FLT - no clamp function. |
| PGOOD (Pin 16) | Power status indicator | Active-high open-drain output; goes high only when FET is fully enhanced and VOUT ≥ 90% of VIN. |
| FLT (Pin 15) | Fault event flag | Open-drain active-low signal asserting UVLO, OVP, overcurrent, thermal, or short-circuit faults - debounced per timing specs. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable UVLO/OVP cutoff | ±2% threshold accuracy enables precise bus supervision without external supervisors - reduces BOM count in PLC backplanes. |
| Thermal regulation loop | Automatically modulates dV/dt during power-up to hold TJ at 145°C (typ), preventing thermal runaway when charging >1000µF loads. |
| Selectable fault response | MODE pin configures latch-off (safe for critical systems) or auto-retry (resilient for transient faults) - no firmware required. |
| Analog current monitor (IMON) | ±6% gain accuracy (27.9 µA/A typical) provides real-time load current feedback for predictive maintenance in motor drives. |
| UL 2367 & IEC 62368-1 certified | Pre-certified safety compliance simplifies end-equipment certification for industrial automation and telecom infrastructure. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS16632RGER | Includes adjustable output power limiting (PLIM) and fixed 39V overvoltage clamp; same 24-pin VQFN package. | Required for IEC 61010-1 compliance where power-limited outputs are mandated (e.g., lab equipment). | Select TPS16632RGER if system-level safety standards require output power capping - TPS16630PWPR lacks PLIM and uses OVP cutoff only. |
| TPS26631PWPR | Lower 40V max rating, 3.5A current limit, and no thermal regulation; 20-pin HTSSOP package with identical footprint. | Suitable for cost-sensitive 24V systems without large capacitive loads or stringent transient immunity needs. | Choose TPS26631PWPR for simpler 24V applications where 60V rating and thermal regulation are unnecessary - lower BOM cost but reduced robustness. |
Compared with TPS16630PWPR, TPS16632RGER adds PLIM and OVP clamp for safety-critical compliance, while TPS26631PWPR trades voltage/current rating and thermal regulation for lower cost in non-industrial 24V designs - all three share pin-compatible HTSSOP packaging but differ in protection architecture and spec coverage.

FAQ
What is the maximum continuous current rating of the TPS16630PWPR?
The TPS16630PWPR supports 6A continuous output current with RON ≤ 53 mΩ across –40°C to +125°C. At 6A and 25°C, conduction loss is ~1.1W. Thermal design must account for ambient temperature, PCB copper area, and airflow to maintain junction temperature below 150°C - the datasheet specifies RθJA = 32.2°C/W for the HTSSOP package.
Does the TPS16630PWPR support output power limiting (PLIM)?
No, the TPS16630PWPR does not support output power limiting. PLIM is exclusive to TPS16632 and TPS16637 variants. The TPS16630PWPR provides adjustable current limiting (0.6–6A), UVLO, and OVP cutoff only - confirmed by TI's Device Comparison Table and Pin Functions table, which omits PLIM pin assignment for TPS16630.
How does the TPS16630PWPR handle inrush current into large capacitive loads?
The TPS16630PWPR uses its dVdT pin to control output slew rate: a capacitor from dVdT to GND sets ramp time (e.g., 22nF → 8.35ms), while leaving dVdT floating enables fastest charge (350–700µs) with automatic thermal regulation fallback if junction temperature exceeds 145°C. This prevents tripping during hot-plug into 1000µF+ loads.
What is the fault response behavior of the TPS16630PWPR during overcurrent events?
The TPS16630PWPR offers selectable fault response via the MODE pin: open = latch-off (FET stays disabled until SHDN cycle), grounded = auto-retry (attempts restart after 500–800ms). Overcurrent triggers either mode within 2.2–4.5µs for soft shorts or 1µs for hard shorts - independent of PLIM, since TPS16630PWPR lacks that feature.
Is the TPS16630PWPR UL 2367 recognized and IEC 62368-1 certified?
Yes, the TPS16630PWPR is UL 2367 recognized (File No. E169910, RILIM ≥ 3kΩ) and IEC 62368-1 certified. These certifications cover construction, flammability, and electrical safety - enabling direct use in end equipment without additional safety component qualification, provided layout follows TI's thermal and creepage guidelines.
