Texas Instruments TPS16413DRCR

Overview

TPS16413DRCR from Texas Instruments is a 40V, 1.8A current-limiting eFuse IC with IN-to-OUT short detection, ±6% current limit accuracy at 1A, 152mΩ typical R_ON, and latch-off fault behavior. It operates from 2.7V to 40V input, integrates adjustable dV/dt slew control for inrush management, and delivers robust protection in HVAC actuators, medical ventilators, and appliance motor drives.

For engineers reviewing the TPS16413DRCR datasheet, TPS16413DRCR pinout, TPS16413DRCR application, or TPS16413DRCR equivalent, key selection criteria include its configurable current limit (0.03–1.8A), 10-pin VSON package with thermal PowerPAD™, latch-off response to overcurrent, and integrated IN-to-OUT short detection for IEC 62368-1 and UL 2367 compliant designs.

Technical Context

The TPS16413DRCR implements active current limiting using an internal N-channel FET with 152mΩ typical on-resistance, where output current is set via an external resistor on the ILIM pin and transient overload tolerance is managed by a capacitor on IDLY. Its fault logic latches off upon overcurrent or thermal shutdown, requiring manual reset via EN/SHDN.

IN-to-OUT short detection triggers FLT assertion within 135ms when the FET is ON, enabling system-level diagnostics or external PFET control. The dV/dt pin provides programmable output slew rate using an external capacitor, directly controlling inrush current into large capacitive loads during power-up.

FAQ

What is the maximum input voltage rating for the TPS16413DRCR?

The TPS16413DRCR supports a continuous 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-though the internal FET itself is limited to 40V operation. Absolute maximum IN voltage is 42V.

How does the TPS16413DRCR implement IN-to-OUT short detection?

The TPS16413DRCR detects resistance below 30mΩ between IN and OUT pins and asserts the FLT pin within 135ms when the internal FET is ON, or within 20ms when the FET is OFF. This hardware-based detection eliminates reliance on external comparators or microcontroller polling, fulfilling IEC60335 short-circuit test requirements.

What is the purpose of the IDLY pin on the TPS16413DRCR?

The IDLY pin on the TPS16413DRCR sets the blanking time window for transient overcurrent events. A capacitor connected to IDLY (e.g., 12nF yields 6.5ms) allows startup surges-such as motor inrush-to pass without triggering current limiting, while still enforcing the 1.8A limit after the blanking period expires.

Does the TPS16413DRCR provide current monitoring capability?

Yes, the TPS16413DRCR provides analog current monitoring via the IOCP/IMON pin, delivering a proportional output current with 50µA/A gain and ±0.8µA offset. This enables real-time load current telemetry for diagnostics, predictive maintenance, or closed-loop control without adding external sense resistors or amplifiers.

What fault response behavior does the TPS16413DRCR use?

The TPS16413DRCR uses latch-off fault behavior: upon overcurrent, thermal shutdown, or IN-to-OUT short detection, it disables the internal FET and holds FLT low until the EN/SHDN pin is actively cycled (driven low then high). This prevents uncontrolled auto-retry, ensuring safe, deliberate system recovery in safety-critical applications.
