Product details
Overview
TPS16411DRCR from Texas Instruments is a 40V, 1.8A power-limiting eFuse with integrated IN-to-OUT short detection, ±5% accurate 15W power limiting (at 15W), 152mΩ typical RON, and latch-off fault behavior. It operates from 4.5V to 40V input, supports dV/dt-controlled inrush protection, and delivers robust overvoltage, overtemperature, and transient overload protection in industrial appliance power rails.
For engineers reviewing the TPS16411DRCR datasheet, TPS16411DRCR pinout, TPS16411DRCR application, or TPS16411DRCR equivalent, this device is selected for IEC60335/UL60730-compliant low-power circuit (LPC) protection where precise 15W power limiting, IN–OUT short diagnostics via FLT, and thermal-safe latch-off response are required.
Technical Context
The TPS16411DRCR implements a precision power-limiting architecture using an internal 152mΩ N-channel FET and feedback-controlled current sensing. Its PLIM pin sets output power limit via resistor (e.g., 255kΩ → 37W), while PDLY configures blanking time for transient loads - critical for motor startup in HVAC actuators without false trips.
IN-to-OUT short detection triggers FLT within 135ms (FET ON) or 20ms (FET OFF), enabling immediate system-level fault isolation. The device integrates OVP (1.53V threshold), thermal shutdown at 155°C, and dV/dt slew control via external capacitor - all operating across –40°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 40V - supports wide industrial DC bus inputs including 12V, 24V, and 36V systems. |
| Power Limit Accuracy | ±5% at 15W - meets IEC60335 and UL60730 requirements for low-power circuit (LPC) protection. |
| RON (Typical) | 152mΩ - minimizes conduction loss (≤0.5W at 1.8A), reducing thermal stress in compact PCB layouts. |
| Fault Response | Latch-off - prevents automatic recovery after overcurrent or short-circuit events until EN/SHDN reset. |
| IN–OUT Short Detection | 30mΩ threshold - detects hard shorts between input and output pins, eliminating need for external test circuitry. |
| Operating Junction Temp | –40°C to +125°C - qualified for harsh environments like oven control modules and refrigeration compressors. |
| Package | VSON-10 (DRC), 3.0mm × 3.0mm - small-footprint QFN with PowerPAD™ for enhanced thermal dissipation (RθJA = 43.7°C/W). |
Pinout & Package
VSON-10 (DRC) package: 3.0mm × 3.0mm body, 0.5mm pitch, exposed PowerPAD™ thermal pad requiring GND connection via multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power input | High-side input node connected to upstream supply; withstands up to 40V continuous, –1V negative transients. |
| OUT | Power output | Switched output driving protected load; features ultra-low RON and IN–OUT short detection path. |
| EN/SHDN | Enable/shutdown control | Logic-level input: >1.2V enables, <0.59V disables; 24ms low pulse enters full shutdown (IQSD ≤ 36µA). |
| PLIM | Power limit setpoint | Analog input accepting resistor (12.4kΩ–412kΩ) to configure 3W–39.8W power limit per design. |
| PDLY | Power-limit blanking timer | Capacitor-connected input setting delay before power limiting activates - avoids tripping on motor startup surges. |
| FLT | Active-low fault indicator | Open-drain output signaling OVP, OTP, IOCP, or IN–OUT short; drives MCU GPIO or external PFET gate. |
| IOCP/IMON | Current sense & monitoring | Provides 50µA/A gain for real-time load current readback; also sets overcurrent trip threshold via resistor. |
| dVdT | Output slew rate control | Capacitor-connected pin controlling output ramp rate during turn-on to limit inrush into large COUT. |
| Vcc | Internal regulator supply | Internally generated bias rail; rated to 60V, enabling direct connection to high-voltage OVP divider networks. |
| GND / PowerPAD™ | Ground reference & thermal path | Must be connected to PCB ground plane with ≥4 thermal vias; serves as primary heat dissipation path. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable 15W power limiting | ±5% accuracy at 15W enables compliance with IEC60335/UL60730 LPC safety standards without calibration. |
| IN–OUT short detection | Detects <30mΩ shorts and asserts FLT within 20–135ms - eliminates need for separate short-test circuitry in appliance certification. |
| Latch-off fault behavior | Prevents uncontrolled auto-retry during persistent faults (e.g., stuck relay, wiring short), enhancing system safety integrity. |
| Adjustable dV/dt slew control | External capacitor on dVdT pin sets output ramp rate - limits inrush into 470µF+ capacitive loads without external components. |
| Integrated overvoltage protection | OVP input accepts resistor divider to set thresholds from 5.5V to 60V; FLT output can drive external PFET for extended voltage clamping. |
| Thermal shutdown with hysteresis | 155°C trip with 12°C hysteresis ensures stable recovery after cooling - avoids oscillation near thermal limit in enclosed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse power-limiting applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS16410DRCR | Same 15W power-limiting accuracy and latch-off behavior, but lacks IN–OUT short detection. | Suitable only where short-detection is handled externally or not required by safety standard. | Select TPS16410DRCR if IN–OUT short test is omitted from design validation and board space allows external diagnostic circuitry. |
| TPS25982LDDAR | Higher 2.7A current limit, ±1.5% power accuracy, but no IN–OUT short detection and requires external OVP. | Targeted at higher-power computing/industrial rails; not certified for IEC60335 LPC use cases. | Choose TPS25982LDDAR when >1.8A continuous current and tighter power tolerance are needed, and safety certification scope excludes IN–OUT short testing. |
Compared with TPS16411DRCR, TPS16410DRCR omits critical IN–OUT short detection required for IEC60335 Annex H, while TPS25982LDDAR trades LPC compliance for higher current and accuracy - making TPS16411DRCR uniquely suited for certified appliance control modules.

FAQ
What is the maximum continuous input voltage rating for the TPS16411DRCR?
The TPS16411DRCR supports a continuous input voltage range of 4.5V to 40V on the IN pin. Its Vcc and FLT pins are rated to 60V, enabling use with external PFET-based overvoltage clamping circuits up to that level. Absolute maximum IN voltage is 42V, beyond which permanent damage may occur.
How does the TPS16411DRCR implement IN-to-OUT short detection?
The TPS16411DRCR monitors resistance between IN and OUT pins using an internal comparator with a 30mΩ threshold. When a short occurs, FLT asserts low within 20ms (if FET is off) or 135ms (if FET is on). This feature is exclusive to TPS16410/TPS16411/TPS16412/TPS16413 variants and is integral to IEC60335 Annex H compliance testing.
Can the TPS16411DRCR be used for current limiting instead of power limiting?
No - the TPS16411DRCR is a dedicated power-limiting variant (TPS1641x "power limit" family). It uses the PLIM pin and PDLY timing to regulate POUT = VOUT × IOUT. For current limiting, TI specifies TPS16412/TPS16413/TPS16416/TPS16417, which use ILIM and IDLY pins. Using TPS16411DRCR for current control would result in inaccurate or unstable regulation.
What is the purpose of the dVdT pin on the TPS16411DRCR?
The dVdT pin on the TPS16411DRCR controls output voltage slew rate during turn-on by sinking a 2µA current through an external capacitor. This limits inrush current into large output capacitances (e.g., 470µF), preventing connector arcing and supply droop. Leaving the pin open yields fastest ramp; connecting to GND disables output enable.
Does the TPS16411DRCR meet UL 2367 and IEC 62368-1 certification requirements?
Yes - the TPS16411DRCR carries UL 2367 recognition (File No. E169910, RILM ≥ 5.1kΩ) and IEC 62368-1 CB certification. These approvals validate its suitability in end-equipment requiring recognized component-level safety, including Class II insulated appliances and industrial control panels operating up to 40V.
