Product details
Overview
TPS16410DRCR from Texas Instruments is a 40V, 1.8A power-limiting eFuse IC with integrated IN-to-OUT short detection, ±5% accurate 15W power limiting, 152mΩ typical RON, and configurable blanking time for transient loads. It operates from 4.5V to 40V input, delivers diagnostics via FLT pin, and supports IEC60335/UL60730-compliant low-power circuit protection in appliance control modules.
For engineers reviewing the TPS16410DRCR datasheet, TPS16410DRCR pinout, TPS16410DRCR application, or TPS16410DRCR equivalent, this page provides verified functional specifications, validated pin-level circuit roles, confirmed thermal and timing behavior under load transients, and real-world implementation constraints for industrial appliance power rail protection.
Technical Context
The TPS16410DRCR implements a precision power-limiting architecture using an internal 152mΩ N-channel FET and analog feedback loop that regulates output power (POUT = VOUT × IOUT) to a resistor-programmed setpoint on PLIM. It features dedicated PDLY pin for blanking time configuration and FLT pin that asserts low on IN-to-OUT short, overvoltage, or thermal shutdown.
Unlike current-limiting variants, TPS16410DRCR uses power limiting as its primary fault response-triggering after sustained overload exceeding programmed POUT for tPDLY (6.5ms typ.), with auto-retry recovery. Its OVP input accepts external resistive divider for up to 60V protection when driving external PFET, and dVdT pin enables slew-rate-controlled ramp-up to limit inrush into large capacitive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Input Voltage | 4.5V to 40V - supports wide-range DC bus inputs including 12V, 24V, and 36V industrial systems without external regulation. |
| Power Limit Accuracy | ±5% at 15W - meets IEC60335 and UL60730 requirements for low-power circuit (LPC) protection in safety-critical appliances. |
| RON (Typical) | 152mΩ - minimizes conduction loss (≤0.5W at 1.8A), enabling compact thermal design in QFN 3×3mm package. |
| IN-to-OUT Short Detection | Detects ≤30mΩ shorts within 135ms (FET ON) or 20ms (FET OFF) - eliminates need for secondary protection in IEC compliance testing. |
| Blanking Time (tPDLY) | 6.5ms (typ.) with 12nF capacitor - allows motor startup surges or relay coil energization without false trip. |
| Thermal Shutdown Threshold | 155°C with 12°C hysteresis - protects against sustained overload or poor PCB thermal layout while enabling automatic recovery. |
| FLT Output Type | Open-drain, 73Ω pull-down - directly interfaces with MCU GPIO or drives external PFET for cascaded overvoltage protection up to 60V. |
Pinout & Package
TPS16410DRCR is housed in a thermally enhanced VSON-10 (DRC) package: 3.00mm × 3.00mm body, 0.5mm pitch, exposed PowerPAD™ thermal pad requiring multiple vias to GND plane for optimal junction-to-board thermal resistance (15.8°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power input | High-side switch input node; connects to upstream supply rail (4.5–40V); must be decoupled with ≥10nF ceramic capacitor. |
| Vcc | Internal regulator supply | Internally regulated supply for control logic; rated to 60V; requires local 100nF bypass capacitor. |
| OVP | Overvoltage sense input | Resistive divider input for programmable OVP threshold; connect to GND to disable; open-circuit disables FET. |
| FLT | Fault indicator output | Active-low open-drain output signaling IN-OUT short, OVP, OTP, or power-limit fault; sinks ≥10mA. |
| EN/SHDN | Enable/shutdown control | Logic input: >1.2V enables FET; <0.59V disables; 24ms low pulse enters ultra-low-IQSD (36µA) shutdown mode. |
| PDLY | Power-limit blanking timer | Capacitor-connected input setting 6.5ms blanking window before power-limit activation during transients. |
| dVdT | Output slew rate control | Capacitor-connected input controlling output ramp rate; open = fastest slew; GND = no turn-on. |
| PLIM | Power limit setpoint | Resistor-connected input programming 3–40W power limit range; 255kΩ yields 37W nominal at 25°C. |
| IOCP/IMON | Current monitor & OCP input | Bi-directional pin: sets IOCP trip point (e.g., 2.23A with 7.32kΩ) and outputs 50µA/A current-sense signal. |
| OUT | Switched power output | Drives protected load; withstands –1V reverse voltage; requires output capacitance ≥100nF for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Accurate 15W power limiting | ±5% tolerance across –40°C to +85°C enables certified LPC protection per IEC60335 and UL60730 without calibration. |
| IN-to-OUT short detection | Identifies ≤30mΩ faults in <135ms and asserts FLT - removes need for external test circuitry during safety certification. |
| Configurable output slew rate | dVdT pin controls ramp time (e.g., 105µs with no cap); prevents connector arcing and system supply droop during hot-plug events. |
| Auto-retry fault recovery | After power-limit trip, device automatically retries every 8×tPDLY (52ms) - maintains uptime in intermittent overload conditions. |
| 60V overvoltage protection support | OVP pin + FLT-driven external PFET extends input protection beyond 40V rating - critical for HVAC and industrial 48V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse power-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS16411DRCR | Latch-off fault behavior instead of auto-retry; identical power limiting accuracy and pinout. | Suitable where permanent isolation is required after first fault (e.g., non-resettable safety interlocks). | Select TPS16411DRCR when system architecture mandates manual reset after overcurrent event. |
| TPS25942ARVCR | Higher 2.7A current limit (not power limit); 28V max input; no IN-OUT short detection; different pinout and footprint. | Better suited for high-current digital load switching where precise power capping is not required. | Choose TPS25942ARVCR only if application prioritizes current limiting over power limiting and operates below 28V. |
Compared with TPS16410DRCR, TPS16411DRCR offers identical protection specs but latches off permanently on fault-requiring external reset-while TPS25942ARVCR trades power accuracy and IN-OUT short detection for higher current capacity and simpler configuration, making it unsuitable for IEC60335-certified 15W LPC designs.

FAQ
What is the maximum input voltage supported by TPS16410DRCR?
TPS16410DRCR supports an operating 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 PFETs for overvoltage protection up to 60V-though the internal FET itself is limited to 40V. Absolute maximum rating for IN is 42V.
How does TPS16410DRCR implement IN-to-OUT short detection?
TPS16410DRCR detects IN-to-OUT shorts with ≤30mΩ resistance, asserting the FLT pin low within 135ms when the internal FET is ON, or within 20ms when OFF. This feature replaces external test circuitry required for IEC60335 and UL60730 compliance verification, and is exclusive to TPS16410/11/12/13 variants.
Can TPS16410DRCR be used for current limiting instead of power limiting?
No-TPS16410DRCR is a dedicated power-limiting device. It regulates POUT = VOUT × IOUT to a resistor-programmed setpoint on PLIM. For current limiting, TI specifies TPS16412/13/16/17 variants, which use ILIM pin and different internal architecture; TPS16410DRCR lacks current-limiting functionality.
What is the purpose of the PDLY pin on TPS16410DRCR?
The PDLY pin on TPS16410DRCR sets the blanking time window (6.5ms typical with 12nF) before power limiting activates. This allows temporary overloads-such as motor startup currents or relay coil energization-to pass without triggering protection, preventing nuisance trips in dynamic loads.
Does TPS16410DRCR support thermal shutdown and auto-recovery?
Yes-TPS16410DRCR includes overtemperature protection with thermal shutdown at 155°C and 12°C hysteresis. After shutdown, it automatically retries every 52ms (8×tPDLY). This auto-retry behavior distinguishes it from latch-off variants like TPS16411DRCR and supports resilient operation in intermittently overloaded systems.
