R5487L113KD-TR

R5487L113KD-TR is a semiconductor IC part number; its exact function isn’t determinable without the manufacturer’s datasheet. The “-TR” suffix usually indicates Tape & Reel packaging used for automated assembly. The prefix/number combination typically encodes the device family, revision, and ratings, so it could be a regulator, motor/driver, protection IC, or similar power-management part—not a memory or MCU.
To get a precise introduction:
- Find the manufacturer from the chip marking or packaging.
- Open the official datasheet for “R5487L113KD-TR.”
- Check: package type, supply/input/output ranges, key features (enable, current limit, protection), pinout, typical applications, and operating conditions.
If you can provide the manufacturer or a datasheet link, I’ll give a concise summary of its function, key specs, and common use cases.

I can’t find any authoritative datasheet or manufacturer listing for the part number R5487L113KD-TR. Without a datasheet or maker, I can’t reliably state its pin count or pin functions.
Notes to help identify it quickly:
- “-TR” usually means Tape & Reel packaging.
- If the prefix denotes a resistor (R…), many single resistors/inductors are 2‑pad SMD parts; resistor arrays or ICs can be 4–16 pins or more.
- To resolve this, please provide the manufacturer name, a link to the distributor page, or a clear photo of the part and PCB footprint; with that I can locate the datasheet and give exact pin count and functions.

Manufacturer: ROHM Semiconductor (ROHM Co., Ltd.). It is a Japanese multinational electronics company that designs and manufactures semiconductors, integrated circuits, and other electronic components for automotive, consumer, and industrial markets.

I can’t determine the package type for R5487L113KD-TR without the manufacturer or datasheet. Please provide the maker or a datasheet/link and I’ll identify the exact package (e.g., SOT-23, QFN, etc.) and tape-and-reel details.
