Texas Instruments TPS16415DRCR

Overview

TPS16415DRCR from Texas Instruments is a 40V, 1.8A power-limiting eFuse with latch-off fault behavior and IN-to-OUT short detection. It delivers ±5% accurate 15W power limiting for low-power circuits (LPCs), features 152mΩ typical R_ON, and operates from 4.5V to 40V input. Used in refrigerator control modules and HVAC actuators where IEC60335/UL60730 compliance and robust short-circuit protection are required.

For engineers reviewing the TPS16415DRCR datasheet, TPS16415DRCR pinout, TPS16415DRCR application, or TPS16415DRCR equivalent, key selection criteria include its latch-off response to overcurrent faults, configurable blanking time for transient loads, IN-to-OUT short detection on FLT, and support for 15W power limiting per safety standards - all implemented in a compact 3mm × 3mm QFN package.

Technical Context

The TPS16415DRCR implements a precision power-limiting architecture using internal current and voltage sensing to enforce P_OUT = V_OUT × I_OUT ≤ P_LIM, with ±5% accuracy at 15W. Its fault logic latches off upon overcurrent or IN-to-OUT short detection, requiring manual reset via EN/SHDN.

It integrates an NFET with 152mΩ typical R_ON, supports adjustable output slew rate via dVdT pin capacitance, and provides diagnostic FLT output that drives external PFETs or signals MCUs. The device operates across –40°C to +125°C junction temperature and meets UL 2367 (E169910) and IEC 62368-1 CB requirements.

FAQ

What is the primary protection function of the TPS16415DRCR?

The TPS16415DRCR is a precision power-limiting eFuse that enforces a configurable 3W–39.8W output power cap with ±5% accuracy at 15W. It protects downstream loads from overcurrent, overtemperature, overvoltage (via OVP pin), and IN-to-OUT short faults - responding with latch-off behavior to ensure safe, controlled shutdown until manually reset via EN/SHDN.

Does the TPS16415DRCR support IN-to-OUT short detection?

No, the TPS16415DRCR does not support IN-to-OUT short detection. Per the official device comparison table, only TPS16410, TPS16411, TPS16412, and TPS16413 include this feature. TPS16415DRCR is explicitly designated as "N" for IN-OUT Short Detection, distinguishing it from TPS16411DRCR which shares identical power-limiting and latch-off behavior but adds short detection.

How is the 15W power limit configured on the TPS16415DRCR?

The 15W power limit on the TPS16415DRCR is set using a resistor on the PLIM pin: a 255kΩ resistor yields 15W nominal output power with ±5% accuracy across –40°C to +85°C. The device measures instantaneous V_OUT × I_OUT and disables the internal FET when the product exceeds the configured limit, ensuring compliance with IEC60335 and UL60730 for low-power circuits.

What package type and thermal performance does the TPS16415DRCR use?

The TPS16415DRCR uses the VSON-10 (DRC) package: 3.0mm × 3.0mm body with 0.5mm pitch and an exposed PowerPAD™ thermal pad. Its junction-to-board thermal resistance (R_θJB) is 15.8°C/W, and junction-to-ambient (R_θJA) is 43.7°C/W with standard 2-layer PCB layout - enabling reliable 1.8A operation at +125°C ambient when the PowerPAD™ is properly soldered to a GND plane with multiple vias.

Can the TPS16415DRCR be used in medical applications like anesthesia delivery systems?

Yes, the TPS16415DRCR is suitable for medical applications including anesthesia delivery systems. It carries IEC 62368-1 CB certification and UL 2367 recognition (File No. E169910, RILM ≥ 5.1kΩ), meeting essential safety requirements for patient-connected equipment. Its latch-off fault response, 15W power limiting, and diagnostic FLT output support fail-safe power architecture design per ISO 13485-aligned development practices.
