Overview

Description

DS1631AU is a Dallas/Maxim DS1631 digital thermometer sensor with an I2C (two‑wire) interface. It provides local temperature readings from -55°C to +125°C with selectable 9–12‑bit resolution. Key features include a programmable conversion rate, on-chip temperature alarm thresholds (TH/TL) and an ALERT output, plus low power operation with a shutdown/power‑down mode. It typically runs from 2.7–5.5 V and is offered in an 8‑pin package (AU suffix indicates a packaging/lead‑free variant; verify exact package in the datasheet).
Usage snapshot:
- Read the TEMP register for the current temperature.
- Configure resolution and conversion rate as needed.
- Set high/low alarm thresholds to trigger ALERT if exceeded.
Applications include battery packs, server and industrial temperature monitoring, and other embedded systems requiring precise, low‑power temperature sensing. For exact timing, current, and pin settings, consult the DS1631AU datasheet.

Features

DS1631AU is a Dallas/Maxim digital temperature sensor with I2C (2-wire) interface and built-in thermostat features. Key features:
- Temperature range: -55°C to +125°C
- Programmable resolution: 9–12 bits (0.5°C to 0.0625°C steps)
- Programmable high/low temperature limits with hysteresis
- Interrupt/alert output for over/under-temperature conditions
- I2C-compatible serial interface (MBus/SMBus compatible)
- Power supply: 2.7V to 5.5V
- Low power operation with very small standby current
- Configurable conversion mode (one-shot or continuous)
- Address select options (for multiple devices on the same bus)
- 8-pin package (DS1631AU variant)
用途: battery packs, temperature monitoring in electronics, thermal protection.

Package

DS1631AU is in an 8-pin Small-Outline IC package (SOIC-8).

Pinout

The DS1631AU is an 8‑pin device. Pin functions (typical SO/PDIP mapping):
- A2, A1, A0 — hardware address inputs (set the I2C/2‑wire slave address)
- GND — ground
- SDA — serial data (I2C bi‑directional)
- SCL — serial clock (I2C)
- V+ (VCC) — supply voltage
- NC — no connect (unused)
Functionally it is a digital temperature sensor/thermostat with a 2‑wire (I2C‑compatible) serial interface, programmable alarm/thermostat limits, and onboard temperature registers.

Manufacturer

Manufacturer: Dallas Semiconductor (DS), an American semiconductor company that designs and manufactures integrated circuits and sensors (the DS1631AU is one of its temperature-sensor/IC products). Dallas Semiconductor later became part of Maxim Integrated (now part of Analog Devices).

Application

DS1631AU is a digital temperature sensor with I2C interface (9–12 bit, alarm). Typical applications:
- Temperature monitoring in embedded systems and microcontrollers
- Battery packs and power-management thermal protection
- Data loggers and environmental monitoring
- HVAC, refrigeration, and cold-chain systems
- Medical devices needing precise temperature sensing
- Industrial process control and monitoring
- Automotive thermal management and cabin sensors
