TPS26631PWPR 개요
An electronic fuse (eFuse) is a semiconductor protection device that replaces legacy mechanical fuses and PTC resettable devices. Compared with discrete hot-swap designs (MOSFET + sense resistor + op-amp + comparator), an integrated eFuse combines inrush limiting, current limit, over-voltage clamp, thermal fold-back and fault output in a single IC. eFuse devices sit in the protection hierarchy between TVS/TVS-diode (transient suppressor) and discrete hot-swap controllers, and they are classified within power management ICs for industrial systems. They are widely adopted in 24-V factory automation backplanes, 48-V telecom and battery-powered industrial loads where hot-plug, surge and reverse-polarity events are routine.
Key features of the TPS26631PWPR include programmable output power limiting (dV/dT controlled turn-on), integrated surge protection, fault output flag, thermal shutdown, and ±7% ILIM accuracy over temperature. The HTSSOP-20 PowerPAD provides a low thermal resistance path, enabling continuous 6-A operation on moderate copper area. Power limiting lets the device ride through large transient overloads without nuisance tripping while still protecting upstream supplies.
The TPS26631PWPR uses TI's HotSwap architecture with an integrated charge pump gate driver for the internal N-FET. The reference design supports either independent mode (ILIM resistor to GND) or closed-loop power limiting via the PLIM resistor. A fault timer programs the retry/delay behavior after an OCP/OVP event, and the IMON pin provides analog load-current monitoring for system telemetry.
Typical applications include 24-V industrial PLC I/O protection, factory-automation sensor and actuator rails, 48-V telecom rectifier secondary protection, motor-driver pre-regulation, and battery-powered industrial equipment with hot-plug battery packs. The wide 4.5-V to 60-V operating window also suits solar and renewable energy harvesters.
Designers should size upstream capacitance so that inrush (dV/dT programmed by CDEV) does not exceed the current-limit threshold at power-on, and they should connect the PowerPAD to a sufficient copper pour to keep junction rise below 100 °C at 6-A continuous load.

일반적인 애플리케이션
TPS26631PWPR 적합 용도: 7 애플리케이션s: 24-V Industrial PLC I/O Protection, 48-V Telecom Rectifier Secondary Protection, Industrial Motor-Driver Pre-Regulation, Battery-Powered Industrial Equipment / Hot-Plug Packs, Solar / Renewable Energy Harvesting Rail Protection, Factory-Automation Sensor / Actuator Bus, Portable Industrial Test & Measurement Equipment.
24-V Industrial PLC I/O Protection
The TPS26631PWPR fits 24-V PLC I/O protection because its 4.5-V to 60-V operating range fully encompasses the 24-V nominal industrial bus plus ±20% tolerance transients. Its integrated 31 mΩ N-FET carries up to 6 A continuously for solenoid, relay and actuator loads without external MOSFETs. The adjustable current limit (0.6-6 A, ±7%) lets the designer set ILIM just above the steady actuator current to trip on stall, while the power-limit feature rides through motor start-up surges without nuisance shutdown. Reverse-polarity protection using an external N-FET protects PLC modules from miswired field wiring - a frequent cause of field failures - and the FLT pin feeds the PLC's diagnostic input for predictive maintenance.

48-V Telecom Rectifier Secondary Protection
The TPS26631PWPR fits 48-V telecom rectifier secondary protection because its 60-V maximum operating voltage and 67-V abs-max rating cover the nominal -48-V backplane plus transient ringing. The integrated 31 mΩ FET drops only ~280 mV at 6 A, leaving ample margin for downstream Point-of-Load converters. Power limiting prevents the eFuse from tripping during load-step transients that exceed ILIM for tens of milliseconds, while still protecting the upstream OR-ing controller from a shorted downstream POL. The FLT and IMON outputs feed the system supervisor for telemetry and remote fault reporting required in telecom-grade hardware.
추천
Industrial Motor-Driver Pre-Regulation
The TPS26631PWPR fits motor-driver pre-regulation because the integrated 31 mΩ FET handles the inrush of bulk DC-link capacitance at start-up, while the dV/dT-controlled turn-on (CDEV pin) prevents the input supply from collapsing when multiple drives are hot-plugged into a shared 24-V or 48-V bus. The 0.6-6 A adjustable ILIM matches typical stepper and small servo drive rails, and the ±7% current-limit accuracy avoids nuisance trips during normal load transients. Reverse-polarity protection via an external N-FET defends against motor back-EMF events that can pull the bus below ground.
추천
Battery-Powered Industrial Equipment / Hot-Plug Packs
The TPS26631PWPR fits hot-plug battery pack protection because its reverse-current blocking (with an external N-FET in the return path) prevents the bus from back-driving a depleted or removed battery - a critical safety requirement for hot-swappable industrial battery systems. The 4.5-V to 60-V operating window spans 12-V, 24-V and 48-V battery stacks, and the integrated 31 mΩ FET keeps conduction loss low enough that thermal rise is acceptable without a heatsink. The FLT pin signals the BMS host MCU when the eFuse has latched off due to OCP, OVP, or thermal shutdown, enabling graceful system shutdown.
추천
Solar / Renewable Energy Harvesting Rail Protection
The TPS26631PWPR fits solar PV and renewable energy harvesting rail protection because the wide 4.5-V to 60-V input window covers 12-V, 24-V, and 48-V PV string rails, and the 67-V abs-max rating tolerates open-circuit PV voltage spikes under cold conditions. The integrated 31 mΩ FET minimizes steady-state loss on energy-harvested rails where every milliwatt matters. Programmable dV/dT inrush control prevents the input capacitor from drawing a surge that exceeds the panel's short-circuit current capability, and the FLT output signals the system controller when the rail has been disconnected due to a fault.
추천
Factory-Automation Sensor / Actuator Bus
The TPS26631PWPR fits factory-automation sensor and actuator bus protection because the integrated 31 mΩ FET plus 0.6-6 A adjustable current limit handles a wide range of field devices on a shared 24-V backplane. Reverse-polarity protection via an external N-FET defends against miswired field cabling, and the surge-protection feature absorbs transient over-voltage events caused by inductive load switching on adjacent lines. The IMON pin provides analog load-current telemetry for predictive maintenance, allowing the controller to detect a failing actuator before it fully shorts the rail.
추천
Portable Industrial Test & Measurement Equipment
The TPS26631PWPR fits portable industrial test and measurement equipment because the wide 4.5-V to 60-V input allows the instrument to operate from a 12-V battery, a 24-V bench supply, or a 48-V PoE-derived rail. The integrated 31 mΩ FET delivers up to 6 A to internal analog and digital subsystems with minimal drop. The HTSSOP-20 PowerPAD package keeps the design compact for handheld form factors, while the FLT pin and IMON pin feed diagnostic data to the host controller for battery-life optimization and fault logging.

주요 차별점
- Integrated 31 mΩ N-FET at 60 V abs-max — eliminates external MOSFET for 6-A loads (vs TPS26631PWPT (same die, but smaller reel size))
- Drop-in same-package variants cover alternative fault-response profiles without PCB rework (vs TPS26636PWPR / TPS26632PWPR / TPS26630PWPR / TPS26633PWPR)
- Programmable power limiting rides through surge transients that would trip a current-limit-only eFuse (vs Discrete MOSFET + comparator + sense resistor hot-swap)
설계 노트
Estimated: at 6 A continuous through the integrated 31 mΩ FET, conduction loss is approximately 1.1 W (I² × R = 36 × 0.031). The HTSSOP-20 PowerPAD typically achieves θJA around 30-35 °C/W on a 1-oz, 4-layer board with a 1-sq-inch thermal pour. At 1.1 W and θJA ≈ 32 °C/W, junction rise above ambient is about 35 °C, leaving ample margin below the 125 °C thermal shutdown threshold. For continuous 6-A operation in still air, expand the PowerPAD copper pour to at least 2 sq inches and add thermal vias to internal ground planes.
Place the input bulk capacitor (≥ 1 μF X7R 100 V) and output bulk capacitor (≥ 1 μF X7R 100 V) within 5 mm of the IN and OUT pins to minimize parasitic inductance in the high-current path. Connect the PowerPAD to a continuous ground copper pour on the top layer with at least 4 thermal vias (0.3 mm drill) to an internal ground plane to keep θJA low. Route the ILIM, PLIM, CDEV, and TIMER traces away from the IN/OUT switching node to avoid noise coupling into the analog control loop.
Common pitfalls when designing with the TPS26631PWPR: (1) sizing the ILIM resistor at the wrong value - use the TI datasheet formula ILIM(A) ≈ 12 / RILIM(kΩ) and 1% tolerance resistors; (2) forgetting the dV/dT capacitor on CDEV, which causes uncontrolled inrush that exceeds ILIM and trips the part on power-up; (3) neglecting reverse-polarity protection - the GATE pin requires an external N-FET in the return path for reverse-current blocking; (4) using the wrong TVS clamping voltage for surge - select a 60-V or 65-V working voltage TVS to coordinate with the 67-V abs-max input rating.
