概述

Description

Introduction to LMT70YFQR
- LMT70YFQR is TI’s LMT70 family precision analog temperature sensor in a compact surface-mount package.
- It provides a voltage output that is linearly proportional to ambient temperature from a single supply (no digital bus required).
- Features include low quiescent current, good linearity and accuracy, and wide operating temperature range.
- Ideal for simple thermal monitoring in mobile/portables, wearables, battery packs, and general consumer electronics.
- Advantages: small footprint, low power, easy MCU interface via ADC, wafer-calibrated for reliable performance.
- For exact specs (temperature range, accuracy, output slope, and pinout), consult the TI LMT70YFQR datasheet and product page.

Features

Key features of TI LMT70YFQR (typical):
- Digital temperature sensor with linearized I2C interface
- Temperature range: broad operating range (typical -40°C to 125°C)
- Resolution: 0.0625°C (12-bit)
- Accuracy: typically around ±0.25°C over the operating range (factory-calibrated)
- Wide supply: 2.7 V to 5.5 V
- Very low power: active current ~100–150 µA; shutdown current ~1–2 µA
- Fast response: conversion in about 1 ms
- Small package: compact 6-pin package (ROHS-compliant; code suffix relates to package)
- Bus compatibility: I2C (two-wire) with configurable/slave address options
- Calibrated and linearized output; no external trimming required
Note: check the exact datasheet for final operating range, accuracy, and package options for LMT70YFQR in your region.

Package

LMT70YFQR comes in a 6‑pin SC70/SOT‑23‑6 package.

Pinout

Pin count: 8 pins.
Function: LMT70YFQR is a digital temperature sensor (LMT70 family) that outputs calibrated temperature data via a serial interface that is SPI-like (3- or 4-wire). Typical pins provide VDD, GND, CS, SCK, SDI, SDO, with the remaining pins often NC or alternate signals depending on the exact package variant.

Manufacturer

The LMT70YFQR is manufactured by Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, microcontrollers, and embedded processors for electronics and automation.

Application

Applications (LMT70YFQR is a high‑accuracy, low‑power temperature sensor for thermal management):
- Battery packs and portable devices
- Power electronics, adapters and power supplies
- Consumer electronics (PCs, tablets, smartphones, wearables)
- Automotive ECUs and battery management systems
- Industrial automation and sensors
- HVAC and white goods temperature sensing
