Product details
Overview
TPS16417DRCR from Texas Instruments is a 40V, 1.8A current-limiting eFuse with IN-to-OUT short detection, ±6% current limit accuracy at 1A, 152mΩ typical RON, and adjustable dV/dt slew rate control for inrush management. It operates from 2.7V to 40V input and delivers robust protection in HVAC actuators, medical ventilators, and appliance motor drives.
For engineers reviewing the TPS16417DRCR datasheet, TPS16417DRCR pinout, TPS16417DRCR application, or TPS16417DRCR equivalent, key selection factors include its latch-off fault behavior, ILIM/IDLY programmable current limiting, FLT-driven external PFET capability, and QFN-10 (3×3mm) thermal performance with RθJA = 43.7°C/W.
Technical Context
The TPS16417DRCR implements active current limiting using an internal N-channel FET with configurable blanking time via IDLY capacitor and precise ILIM setpoint via external resistor (5.49kΩ yields 1.77A typ). Its fault logic latches off on overcurrent or thermal shutdown - no auto-retry - and asserts FLT low to signal faults or drive external protection circuitry.
IN-to-OUT short detection triggers within 135ms when the FET is ON (20ms when OFF), enabling compliance with IEC60335 and UL60730 safety standards without auxiliary components. The dV/dt pin controls output ramp rate using a capacitor, while OVP supports up to 60V protection with external PFET.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit Accuracy | ±6% at 1A - ensures predictable trip threshold across temperature and supply for reliable load protection |
| RON (typ) | 152 mΩ - minimizes conduction loss and self-heating at 1.8A continuous output |
| Operating Input Range | 2.7V to 40V - supports wide industrial input rails including 3.3V, 5V, 12V, 24V, and 36V systems |
| Output Slew Rate Control | Capacitor-programmable dV/dt - prevents inrush damage to connectors and avoids system-wide supply droop |
| Fault Behavior | Latch-off - holds output disabled after fault until EN/SHDN reset, eliminating uncontrolled retries in safety-critical loads |
| IN-to-OUT Short Detection | Validated down to 30mΩ resistance - detects hard shorts between input and output pins per IEC60335 test requirements |
| Junction Temp Range | –40°C to +125°C - qualified for under-hood, industrial, and medical environments with full parameter operation |
Pinout & Package
TPS16417DRCR uses a 10-pin VSON (DRC) package, 3.00mm × 3.00mm, 0.5mm pitch, with exposed PowerPAD™ thermally connected to GND for enhanced heat dissipation (RθJB = 15.8°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power input | High-side switch input node; connects to upstream supply (2.7–40V); withstands –1V negative transient |
| Vcc | Internal regulator supply | Bias rail for control circuitry; rated to 60V; powers internal logic and gate driver independently of IN |
| FLT | Active-low fault indicator | Open-drain output signaling overcurrent, thermal shutdown, or IN-OUT short; pulls down ≤73Ω to drive MCU GPIO or external PFET gate |
| EN/SHDN | Enable/shutdown control | Logic-level input: ≥1.2V enables, ≤0.59V disables; 24ms low pulse enters ultra-low-IQSD shutdown mode (≤36µA) |
| OVP | Overvoltage sense input | Connect resistor divider from IN to set OVP threshold (1.48–1.58V rising); tie to GND to disable OVP function |
| OUT | Protected power output | Switched output to load; voltage follows IN minus I×RON; supports capacitive loads via dV/dt control |
| IOCP/IMON | Overcurrent setpoint & current monitor | Resistor sets IOCP trip level (e.g., 7.32kΩ = 2.23A); voltage on pin provides real-time current sensing (50µA/A gain) |
| ILIM | Current limit setpoint | Resistor sets final current limit (e.g., 5.49kΩ = 1.77A typ); open or grounded disables current limiting and forces FET OFF |
| IDLY | Blanking time capacitor input | Capacitor sets delay before current limiting engages (6.5ms with 12nF); allows motor startup surges without false trips |
| dVdT | Output slew rate control | Capacitor sets output ramp rate (e.g., 150nF → ~1.5V/ms); open = fastest slew; grounded = no turn-on |
Key Features
| Feature | Design Value |
|---|---|
| Latch-off fault response | Ensures single-event fault isolation in life-support and appliance safety systems - no automatic recovery without explicit reset |
| Configurable current limit (0.03–1.8A) | Set via single external resistor on ILIM pin; supports diverse loads from sensors to 24V DC motors without redesign |
| IN-to-OUT short detection (30mΩ threshold) | Eliminates need for separate short-circuit test circuitry during IEC60335/UL60730 certification testing |
| Adjustable dV/dt slew rate | Prevents connector arcing and supply droop during hot-plug or large-capacitance power-up - critical for modular PLC backplanes |
| Integrated overtemperature protection | Thermal shutdown at 155°C with 12°C hysteresis prevents permanent damage during sustained overload or poor PCB heatsinking |
| UL 2367 & IEC 62368-1 certified | Reduces safety certification effort for end equipment - recognized file E169910, RILM ≥ 5.1kΩ |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-limiting eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS16416DRCR | Same 10-pin DRC package and latch-off behavior, but auto-retry fault mode instead of latch-off | Suitable for non-safety-critical loads where automatic recovery after transient overloads is acceptable | Select TPS16416DRCR only if system-level fault handling permits repeated FET cycling without risk of thermal runaway |
| TPS25982LDDAR | Higher 2.7A current rating, 3.5mΩ RON, and integrated telemetry (I/V/T reporting over I²C), but no IN-OUT short detection | Targets data center and telecom power distribution where digital monitoring outweighs safety-test compliance | Choose TPS25982LDDAR when bus telemetry and lower conduction loss are prioritized over IEC60335 short-detection certification |
Compared with TPS16417DRCR, TPS16416DRCR offers identical current limiting and package but sacrifices safety-critical latch-off behavior for auto-retry, while TPS25982LDDAR trades IN-OUT short detection and safety certification for digital interface and lower RON - making TPS16417DRCR optimal for certified white-goods and medical subsystems.

FAQ
What is the maximum input voltage the TPS16417DRCR can withstand?
The TPS16417DRCR supports an operating input voltage range of 2.7V 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 - but the internal FET's safe operating area remains limited to 40V on IN. Exceeding 40V on IN risks permanent damage.
How does the TPS16417DRCR differ from the TPS16412DRCR?
The TPS16417DRCR and TPS16412DRCR share identical current-limiting architecture, pinout, and 1.8A rating, but differ in fault behavior: TPS16417DRCR latches off permanently after overcurrent or thermal fault, while TPS16412DRCR auto-retries after tRETRY delay. Both support IN-OUT short detection and dV/dt control.
Can the TPS16417DRCR be used without connecting the dVdT pin?
Yes - leaving the dVdT pin open enables the fastest possible output slew rate on the TPS16417DRCR. However, this may cause excessive inrush current into large output capacitances. For controlled ramp-up, connect a capacitor (e.g., 150nF) to dVdT; grounding the pin prevents output turn-on entirely.
What is the purpose of the IDLY pin on the TPS16417DRCR?
The IDLY pin on the TPS16417DRCR accepts an external capacitor to set blanking time (6.5ms typical with 12nF) before current limiting activates. This allows brief overcurrent events - such as motor startup surges - to pass without triggering ILIM, preventing nuisance trips while maintaining protection during sustained faults.
Does the TPS16417DRCR provide current monitoring functionality?
Yes - the TPS16417DRCR provides analog current monitoring via the IOCP/IMON pin, delivering 50µA/A (±5µA) output current proportional to load current, with ±0.8µA offset. This enables real-time diagnostics and closed-loop current supervision without additional sense resistors or amplifiers.
