Thermal Management datasheet and documents for DS1629S/T&R

DS1629S/T&R

Thermal Management Overview

The DS1629S/T&R is a digital thermometer and real-time clock integrated in an 8-pin SO package. It measures temperatures from -55°C to +125°C with ±2.0°C typical accuracy and 9-bit resolution. The RTC counts seconds, minutes, hours, date, month, day of week, and year with leap year compensation through 2100. It features a 2-wire serial interface, user-definable thermostatic and time alarms via an open-drain output, and 32 bytes of SRAM for data storage. Operating voltage ranges from 2.2V to 5.5V.

Thermal Management Feature Summary

Integrates a factory-calibrated digital thermometer and a real-time clock/calendar with automatic date adjustments.
Provides user-configurable alarm outputs triggered by temperature thresholds or specific time events.
Includes 32 bytes of non-volatile SRAM for general system data logging and storage.
Communicates via a standard 2-wire serial interface requiring minimal external components.

Thermal Management Applications

Personal computers and PDAs
Cellular telephones
Office equipment
Thermal data loggers

Thermal Management Procurement Notes

Verify the component matches the exact DS1629S+T&R designation, ensuring the T&R suffix indicates tape and reel packaging. Confirm the lead-free/RoHS-compliant status indicated by the plus sign. Check that the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the 8-pin SO package dimensions align with your PCB layout requirements before finalizing procurement.

Thermal Management Selection Notes

Select this component when a combined temperature monitoring and timekeeping solution is required in a compact form factor. It is suitable for battery-powered applications due to its wide supply voltage range and low power consumption options. Consider the 2-wire interface compatibility with your microcontroller. Ensure the operating temperature range of -55°C to +125°C meets your environmental specifications.

Thermal Management Part Context

The DS1629 belongs to the Maxim Integrated (now Analog Devices) family of digital thermal sensors and real-time clocks. It combines the functionality of the DS1620 thermometer and DS1672 RTC into a single device. This integration reduces board space and component count compared to using separate ICs for temperature sensing and timekeeping functions in embedded systems.
