Product details
Overview
TPS26635RGER 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 fast reverse current blocking (0.17µs). It delivers power path protection in PLC I/O modules and motor drive encoder supplies under IEC61000-4-5 surge conditions.
For engineers reviewing the TPS26635RGER datasheet, TPS26635RGER pinout, TPS26635RGER application, or TPS26635RGER equivalent, this device supports precise output power limiting (±6%), programmable slew rate control, latch-off/auto-retry fault response selection, and reverse polarity protection via external N-FET - critical for robust industrial power rail design.
Technical Context
The TPS26635RGER implements a dual-stage protection architecture: fast-trip short-circuit detection (1µs) combined with active current limiting (2.2–4.5µs soft-short response) and thermal regulation (136–154°C set point). Its PLIM pin enables programmable output power limiting up to 160W at 54V input, meeting IEC61010-1 and UL1310 compliance requirements.
It integrates a B-GATE driver (8.3–14V clamp, 16–23µA drive) and DRV pulldown switch for external reverse-current-blocking N-FET control, while PGOOD provides enable/disable signaling for downstream DC-DC converters. The device achieves Class-A performance during IEC61000-4-4/4-5 surge events without external TVS dependency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5V to 60V input range; supports 24V/48V industrial rails with 67V absolute max rating. |
| RON | 30.44mΩ typical (25°C); ensures <1.8W conduction loss at 6A, enabling compact thermal design. |
| Current Limit Range | 0.6A–6A adjustable via ILIM resistor (±7% accuracy); supports scalable load protection across system variants. |
| Overvoltage Clamp | Fixed 39V clamp (TPS26635-specific); limits transient overvoltage to safe levels for downstream 36V-rated components. |
| Power Limit Accuracy | ±6% output power limiting (PLIM pin); enables precise compliance with safety standards like UL1310 without recalibration. |
| Reverse Current Blocking | 0.17µs detection delay; prevents backfeed during hot-swap or supply failure in redundant power systems. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power input | Connects to drain of internal 31mΩ FET; accepts 4.5–60V supply with 67V transient tolerance. |
| B_GATE | Blocking FET gate driver | Drives external N-FET gate for reverse polarity protection; 8.3–14V clamp prevents gate overstress. |
| PLIM | Power limit programming input | Resistor-to-GND sets max output power (e.g., 100kΩ = 100W); enables IEC61010-1-compliant design. |
| ILIM | Current limit programming input | Resistor-to-GND configures 0.6–6A trip threshold (±7%); supports factory-set or field-adjustable protection. |
| MODE | Fault response selector | Open = latch-off; grounded = auto-retry; determines system recovery behavior after overcurrent event. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS26633RGER | Same 24-pin RGE package and 35V overvoltage clamp; identical PLIM and pulse-overcurrent support. | Lower 35V clamp suits 36V-rated downstream ICs; requires revalidation of overvoltage margin in 48V systems. | Select when system maximum bus voltage is ≤40V and tighter overvoltage clamping is required. |
| TPS26637RGER | Same RGE package, 39V clamp, and PLIM functionality; lacks OVP cutoff option but adds 2x pulse overcurrent support. | Optimized for high-pulse-load applications (e.g., solenoid drivers); no OVP cutoff simplifies design where clamp-only protection suffices. | Choose for systems with intermittent high-current loads and no requirement for overvoltage cutoff behavior. |
Compared with TPS26635RGER, TPS26633RGER offers lower overvoltage clamping (35V vs. 39V) for tighter downstream voltage margins, while TPS26637RGER retains the 39V clamp but removes OVP cutoff - making it ideal for pulse-dominated loads where sustained overvoltage is not a concern.

FAQ
What is the overvoltage protection behavior of the TPS26635RGER?
The TPS26635RGER features a fixed 39V overvoltage clamp - not a cutoff - meaning it regulates output voltage at ~39V during overvoltage events rather than disconnecting the load. This behavior is confirmed in the Electrical Characteristics table (VOVC = 35.7–39V) and distinguishes it from TPS26630/31 variants that offer adjustable OVP cutoff. The clamp remains active until input voltage falls below the hysteresis threshold.
How does the TPS26635RGER implement reverse polarity protection?
The TPS26635RGER enables reverse polarity protection using its B_GATE and DRV pins to drive an external N-channel FET. When reverse voltage is detected (VIN_SYS – VOUT < –9 mV), the device asserts DRV within 0.17µs to pull down the external FET's gate, blocking reverse current. This is distinct from internal FET-based protection and requires external component selection per the datasheet's RCB section.
What is the accuracy and range of the adjustable current limit on the TPS26635RGER?
The TPS26635RGER supports 0.6A to 6A adjustable current limiting via the ILIM pin resistor, with ±7% accuracy across temperature (–40°C to +125°C). For example, a 3kΩ resistor sets 6A nominal (5.58–6.42A), while a 30kΩ resistor sets 0.6A (0.54–0.66A). This range is validated in Table 6-5 and Figure 6-9 of the datasheet.
Does the TPS26635RGER support both auto-retry and latch-off fault responses?
Yes, the TPS26635RGER supports both fault responses via the MODE pin: open-circuit configures latch-off (requires SHDN toggle to reset), while grounding MODE enables auto-retry with 550–800ms retry delay. This dual-mode capability is explicitly documented in the Device Functional Modes section and Table 4 (Device Comparison Table).
What certifications apply to the TPS26635RGER?
The TPS26635RGER is UL 2367 recognized (File No. E169910, RILIM ≥ 3kΩ) and IEC 62368-1 certified. These certifications validate its safety compliance for industrial end-equipment, including insulation, flammability, and fault-condition behavior - critical for CE-marked PLCs and motor drives.
