Product details
Overview
TPS26636PWPT from Texas Instruments is a 60V, 6A industrial eFuse with integrated 31mΩ hot-swap FET, fixed 39V overvoltage clamp, adjustable current limit (0.6–6A ±7%), analog current monitor (±6%), and power-good output. It delivers fast reverse-current blocking (0.17µs), IEC 61000-4-4/4-5 surge immunity, and thermal regulation for PLC power path protection.
For engineers reviewing the TPS26636PWPT datasheet, TPS26636PWPT pinout, TPS26636PWPT application, or TPS26636PWPT equivalent, key selection criteria include its HTSSOP-20 package, 39V fixed OVP clamp, single-pulse (1×) overcurrent fault response, and verified compliance with UL 2367 (E169910) and IEC 62368-1.
Technical Context
The TPS26636PWPT implements a precision current-limiting architecture with programmable ILIM resistor input and integrated power-limiting (PLIM) control via external PLIM resistor (60.4–150kΩ), enabling stable 100W max output power at 54V input. Its B_GATE/DRV dual-gate driver supports external N-FET reverse polarity protection with sub-microsecond detection.
It features independent UVLO (14.47–15.46V trip), PGOOD comparator (1.123–1.224V threshold), and fast-trip short-circuit protection (<1µs response). Thermal regulation activates at 136–154°C, with shutdown at 165°C and 11°C hysteresis - all operating across –40°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5V to 60V input; 67V absolute max - supports wide industrial rail voltages including 24V and 48V systems. |
| RON | 30.44 mΩ typical at 25°C - minimizes conduction loss and self-heating under 6A load. |
| Current Limit Range | 0.6A to 6A ±7% via ILIM resistor - enables precise overload protection tuning without firmware. |
| OVP Clamp | Fixed 39V max (TPS26635/TPS26636 only) - clamps transients to protect downstream 40V-rated DC-DC converters. |
| Power Limit Accuracy | ±6% PLIM accuracy with RPLIM = 100kΩ - ensures reliable compliance with IEC 61010-1 energy-limited circuit requirements. |
| Reverse Blocking Speed | 0.17µs detection delay - prevents backfeed damage during hot-swap or supply reversal in redundant power systems. |
| PGOOD Threshold | 1.2V ±2% rising edge - provides clean enable signal for downstream regulators after safe output ramp-up. |
Pinout & Package
TPS26636PWPT uses a 20-pin HTSSOP (PWP) package (6.50mm × 4.40mm) with exposed PowerPad™ for thermal dissipation. Pin 1 is top-left corner (marking dot adjacent), and PowerPad must be soldered to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (pins 1,2,3) | Power input node | Connects to drain of internal 31mΩ FET; accepts up to 60V continuous, 75V transient. |
| B_GATE (pin 4) | Blocking FET gate driver | Drives external N-FET gate for reverse polarity protection; 10.23V clamp limits gate stress. |
| IN_SYS (pin 6) | Device supply reference | Provides bias for internal circuitry; tied to IN when no external FET is used. |
| PLIM (pin 8) | Power limit set input | Resistor-to-GND sets max output power (e.g., 100W @ 100kΩ); unused → connect to GND. |
| ILIM (pin 11) | Current limit programming | Resistor-to-GND configures 0.6–6A limit; 3kΩ yields 6A ±7%. |
| MODE (pin 12) | Fault response selector | Open = latch-off; grounded = auto-retry - determines recovery behavior after overcurrent event. |
| SHDN (pin 13) | Enable/disable control | Pull low to enter 21µA shutdown; rising edge resets latched faults. |
| IMON (pin 14) | Analog current monitor | Sources 27.9µA/A scaled current; 1kΩ-to-GND gives 27.9mV/A for precision sensing. |
| PGOOD (pin 17) | Power status flag | Active-high open-drain output asserts when VOUT exceeds PGTH threshold (1.2V). |
| OUT (pins 18,19) | Protected power output | Dual pins reduce trace resistance; delivers regulated current-limited power to load. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 31mΩ FET | Eliminates discrete MOSFET layout complexity and reduces BOM count in 6A hot-swap designs. |
| 39V fixed overvoltage clamp | Protects downstream 40V-input DC-DCs without external TVS, meeting IEC 61000-4-5 Class A surge immunity. |
| Adjustable output power limiting | Enables compliance with safety standards (IEC 61010-1, UL1310) by capping max delivered energy per fault event. |
| Fast reverse current blocking (0.17µs) | Prevents catastrophic backfeed in dual-supply or battery-backup systems during hot insertion/removal. |
| UL 2367 recognition (E169910) | Validates device suitability for use in end-equipment requiring recognized component certification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS26633PWPT | Same HTSSOP-20 package; supports 2× pulse overcurrent (vs. 1× on TPS26636PWPT); identical 39V OVP clamp and PLIM capability. | Preferred where brief inrush surges (e.g., large capacitive loads) require temporary 2× current allowance without fault assertion. | Select TPS26633PWPT if pulse-overcurrent support is required; otherwise TPS26636PWPT offers simpler fault response. |
| TPS26632PWPT | Same package; fixed 35V OVP clamp (vs. 39V); identical PLIM and current limit range; 1× pulse support. | Suitable for 36V nominal systems where tighter OVP margin is needed to protect 36V-rated downstream ICs. | Choose TPS26632PWPT for 36V-rail designs; TPS26636PWPT is optimal for 48V/60V systems needing higher clamp headroom. |
Compared with TPS26633PWPT and TPS26632PWPT, the TPS26636PWPT uniquely balances 39V overvoltage headroom, single-pulse fault response, and full PLIM functionality - making it ideal for 48V industrial power distribution where predictable latch-off behavior and robust surge tolerance are prioritized.

FAQ
What is the maximum continuous input voltage rating for the TPS26636PWPT?
The TPS26636PWPT supports a continuous input voltage range of 4.5V to 60V, with an absolute maximum rating of 67V (10ms transient) and 75V for shorter transients. Its fixed 39V overvoltage clamp activates above this threshold to protect downstream circuitry, making it suitable for 48V industrial systems with margin for line transients.
Does the TPS26636PWPT support reverse polarity protection without external components?
No - the TPS26636PWPT requires an external N-channel FET and associated B_GATE/DRV connections to implement reverse polarity protection. The device provides dedicated gate drivers (B_GATE and DRV) and a reverse-current comparator, but the blocking FET itself is external. Leaving B_GATE floating disables this feature.
How is the current limit set on the TPS26636PWPT, and what is its accuracy?
The TPS26636PWPT uses an external resistor (RILIM) from ILIM pin to GND to set the current limit between 0.6A and 6A. With RILIM = 3kΩ, the device delivers 6A ±7% over temperature (–40°C to +125°C). Accuracy is specified across full operating conditions, not just room temperature.
What is the purpose of the PLIM pin on the TPS26636PWPT, and how is it configured?
The PLIM pin on the TPS26636PWPT sets output power limiting by connecting a resistor (60.4kΩ to 150kΩ) to GND. For example, 100kΩ yields 100W max output power at 54V input. This feature enforces energy-limited fault behavior per IEC 61010-1 and UL1310, and is distinct from current limiting - it acts when VOUT × IOUT exceeds the programmed threshold.
Can the TPS26636PWPT be used in systems requiring UL or IEC safety certification?
Yes - the TPS26636PWPT is UL 2367 recognized (File No. E169910, RILIM ≥ 3kΩ) and IEC 62368-1 certified. These certifications validate its use as a recognized component in end equipment subject to safety standards, including industrial control panels and factory automation systems.
