Description
DS1631AU is Dallas/Maxim’s digital temperature sensor with a two‑wire I2C/SMBus interface. It provides ambient temperature readings as a digital value in a temperature register and supports low‑power operation suitable for embedded systems.
Key points:
- I2C-compatible interface; read temperature directly from a register
- Programmable resolution (9–12 bits) with data in Celsius
- Temperature range roughly -55°C to +125°C
- Programmable high/low temperature alarms with an alert/flag
- Low power: microamps in standby; operates on 2.7–5.5V
- Available in a compact package (AU variant indicates a specific package/grade)
Common uses: system thermal monitoring in PCs/embedded boards, battery packs, consumer and industrial equipment.
For exact electrical specs, timing, and the register map, refer to the DS1631AU datasheet.
