Product details
Overview
TPS26600PWPR from Texas Instruments is a 60-V, 2-A industrial eFuse IC with integrated reverse input polarity protection down to –60 V, 150-mΩ total RON, ±5% current-limit accuracy at 1 A, and selectable fault response (circuit breaker with auto-retry). It serves as a high-voltage load switch and protection controller in programmable logic controllers and redundant power ORing systems.
For engineers reviewing the TPS26600PWPR datasheet, TPS26600PWPR pinout, TPS26600PWPR application, or TPS26600PWPR equivalent, key selection criteria include its adjustable 0.1–2.23-A current limit, 300-µA operating quiescent current, reverse-current blocking capability, and HTSSOP-16 package compatibility with industrial surge (IEC 61000-4-5) requirements.
Technical Context
The TPS26600PWPR integrates back-to-back MOSFETs for bidirectional voltage tolerance (±60 V) and reverse-current blocking, enabling holdup-capable systems during brownouts. Its internal protection control block implements programmable UVLO (14.9 V nominal), OVP cut-off (adjustable up to 55 V), and dV/dt-controlled output slew rate via external capacitor.
Functional safety support includes documentation for system-level design, UL 2367 recognition (File No. 169910), and UL60950 compliance with open/short ILIM detection. The MODE pin configures fault behavior-circuit breaker with auto-retry for TPS26600-while IMON provides ±8.5% accurate analog current monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.2 V to 60 V - supports wide DC bus voltages including 24 V, 36 V, and 48 V industrial supplies |
| Current Limit Accuracy | ±5% at 1 A - enables precise overcurrent protection without calibration overhead |
| Total RON | 150 mΩ max - minimizes conduction loss and thermal rise at 2 A continuous load |
| Quiescent Current | 300 µA typical in operation - sustains low-power monitoring in always-on systems |
| Reverse Polarity Protection | Down to –60 V - eliminates need for external diodes or MOSFETs in negative supply fault conditions |
| Output Slew Rate Control | Adjustable via dVdT pin capacitor - prevents inrush current damage during hot-plug events |
| Operating Temperature | –40°C to +125°C - qualified for harsh industrial environments including control cabinets and DCS nodes |
Pinout & Package
TPS26600PWPR is housed in a 16-pin HTSSOP (PWP) package with 5.00 mm × 4.40 mm body size and exposed PowerPad™ for enhanced thermal performance. The PowerPad must be connected to RTN via multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power input | Main high-voltage supply connection; withstands –60 V to +62 V transients |
| OUT | Power output | Switched load output with integrated back-to-back FETs and reverse-current blocking |
| GND | Ground reference | System ground connection for internal bias circuits and thermal path |
| RTN | Reference node | Analog reference for UVLO, OVP, ILIM, IMON, and dVdT circuits; not signal ground |
| ILIM | Current limit programming | Resistor-to-RTN sets 0.1–2.23-A overload threshold with ±5% accuracy at 1 A |
| IMON | Current monitor output | Analog output sourcing 78.28 µA/A (±8.5%) - converts load current to proportional voltage |
| SHDN | Shutdown control | Active-low enable; pulls device into 20-µA shutdown mode and resets latched faults |
| MODE | Fault response selector | Configures circuit breaker with auto-retry (open), latch-off (402 kΩ), or current-limit (short) |
| UVLO | Undervoltage lockout input | Resistor-to-RTN sets 14.9 V nominal trip point; asserts FLT on brownout |
| OVP | Overvoltage protection input | Resistor-to-RTN sets adjustable cut-off threshold up to 55 V; TPS26600 uses cut-off, not clamp |
| dVdT | Output ramp control | Capacitor-to-RTN sets controlled VOUT rise time; gain = 24.6 V/V |
| FLT | Fault indicator | Open-drain output asserted low on UVLO, OVP, overcurrent, thermal shutdown, or reverse fault |
Key Features

IC Role / Device Role / Timing Role: Bidirectional protection controller managing input selection, inrush control, and fault reporting across dual-supply paths. Use Value: Delivers reverse-current blocking and programmable current limit (±5% at 1 A) to prevent cross-conduction and cascade failures. |
| Industrial Redundant Supply ORing | Control & Automation Power Sequencing |
|
Use Scenario: Implementing N+1 redundant 24/48 V DC supplies in motion control drives where seamless switchover and fault containment are critical. IC Role / Device Role / Timing Role: ORing controller with fast-trip comparator (250 ns) and auto-retry circuit breaker mode for rapid recovery after transient overloads. Use Value: Achieves <10 ms fault response and <540 ms retry delay, minimizing downtime while avoiding nuisance trips on motor startup surges. |
Use Scenario: Managing power-up sequencing of FPGA, MCU, and analog subsystems in industrial HMIs and edge gateways with strict voltage ramp requirements. IC Role / Device Role / Timing Role: Programmable slew-rate limiter using dVdT pin capacitor to enforce controlled VOUT rise time (e.g., 10 ms with 47 nF). Use Value: Prevents simultaneous inrush across multiple rails, eliminating voltage droop and reset glitches without discrete timing components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS26601PWPR | Latch-off fault response instead of auto-retry; identical pinout, RON, and voltage ratings | Suitable where permanent shutdown is required after first overcurrent event (e.g., safety-critical actuators) | Select TPS26601PWPR only if system architecture mandates non-recoverable fault handling |
| TPS25982LARVTR | Higher 3.5-A rating, 2.9-V min input, no reverse polarity protection, different 20-pin VQFN package | Better suited for low-voltage, high-current applications like server POLs; lacks –60 V reverse tolerance | Choose TPS25982LARVTR only when input is ≤36 V and reverse protection is handled externally |
Compared with TPS26600PWPR, TPS26601PWPR offers deterministic latch-off behavior for fail-safe shutdown, while TPS25982LARVTR trades reverse polarity support for higher current capacity and lower minimum input voltage-neither is pin-compatible, and both require layout changes and revised protection strategy validation.

FAQ
What is the maximum input voltage rating for the TPS26600PWPR?
The TPS26600PWPR has an absolute maximum input voltage rating of 62 V and a recommended operating maximum of 60 V. It also withstands –60 V reverse input voltage continuously and –70 V for 10-ms transients. This rating enables robust operation across 24 V, 36 V, and 48 V industrial DC buses without external clamping.
Does the TPS26600PWPR provide reverse current blocking?
Yes, the TPS26600PWPR provides active reverse current blocking via integrated back-to-back MOSFETs. When VIN – VOUT falls below –10 mV (typical), the device disables the internal FETs within 1.5 µs to prevent reverse conduction-critical for maintaining output holdup during input brownouts or failures.
How is the current limit set on the TPS26600PWPR?
The TPS26600PWPR current limit is set by connecting a resistor between the ILIM pin and RTN. With RILIM = 5.36 kΩ, the device delivers 2.23-A limit (±5% at 1 A); values from 120 kΩ (0.1 A) to 5.36 kΩ (2.23 A) are supported. Open or shorted RILIM yields defined fail-safe limits per UL60950.
What fault response mode does the TPS26600PWPR use by default?
The TPS26600PWPR defaults to circuit breaker mode with auto-retry when the MODE pin is left open. After an overcurrent event, it shuts off for 540 ms (typical), then automatically attempts reconnection-ideal for recovering from transient surges in motor or solenoid loads without manual reset.
Can the TPS26600PWPR be used in systems requiring functional safety certification?
Yes, the TPS26600PWPR is functional safety capable. Texas Instruments provides documentation-including FIT rate data, failure mode analysis, and diagnostic coverage guidance-to support IEC 61508 and ISO 13849 system-level functional safety certification for industrial machinery and process control applications.
