概述

Description

TMP103EYFFR is a Texas Instruments digital temperature sensor (I2C) in the TMP103 family. It provides a 12‑bit temperature result with a 0.0625°C LSB, typically ranging from −40°C to +125°C, and operates on 2.7–5.5V. It supports low‑power modes (shutdown/one‑shot) and an alert/interrupt output; the I2C address may be configurable via pins in many TMP103 variants. The YFFR suffix indicates RoHS, lead‑free packaging with a Tape & Reel option. To read temperature, fetch two bytes from the temperature register and convert using two’s complement: temp = (raw >> 4) × 0.0625°C. Common applications include embedded temperature sensing in consumer electronics, industrial controls, and battery packs. For exact package type, address options, and electrical characteristics, consult the TMP103 datasheet.

Features

Here are the typical features of the TMP103EYFFR (digital temp sensor):
- I2C two-wire interface (standard/fast modes)
- Temperature range: -40°C to +125°C
- 12-bit temperature data with 0.0625°C LSB (also supports 9–12 bit resolution modes)
- Configurable conversion rate and operation modes (continuous or single-shot)
- Programmable high/low threshold for an alert/interrupt output
- Low power consumption with a shutdown/low-power mode
- 2.7V to 5.5V supply voltage range
- Small, RoHS-compliant package suitable for compact designs
Note: exact package variant and address options may vary by revision; refer to the datasheet for final specifics.

Package

8-pin VSSOP package (VSSOP-8). The suffix FFR indicates tape-and-reel packaging.

Pinout

TMP103EYFFR is a 6‑pin digital temperature sensor (SOT‑23‑6 style). Pin functions:
- V+ (VCC): sensor supply voltage.
- GND: ground.
- SDA: I2C/SMBus data line (bidirectional).
- SCL: I2C/SMBus clock line.
- ADDR: device address select (tie to V+, GND or other levels to set LSB of I2C address).
- ALERT/INT: open‑drain temperature comparator/interrupt output (active low, configurable).
(Per datasheet: I2C interface, factory-configurable resolution/thresholds; ADDR selects the device address on the bus.)

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits and related semiconductor products, serving industrial, automotive, consumer and communications markets.
