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 (RTC) in an 8-pin SO package. It measures temperatures from -55°C to +125°C with ±2.0°C 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 thermostat 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 thermal and time alarms through a dedicated open-drain output pin.
Includes 32 bytes of non-volatile SRAM for general system data logging or histogram 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 specific suffix T&R indicates tape and reel packaging containing 2500 pieces per manufacturer specifications. Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the host system supports the required 2-wire serial protocol and operates within the specified voltage range for reliable EEPROM writes and temperature conversions.

Thermal Management Selection Notes

Select this component when simultaneous timekeeping and local temperature monitoring are required in a compact footprint. It is suitable for battery-powered applications due to its wide supply voltage range and low power requirements. Consider the fixed hardware address limitation which restricts bus topology to a single device or devices with different control codes.

Thermal Management Part Context

This device belongs to the DS1629 series of integrated sensors manufactured by Analog Devices/Maxim Integrated. It combines chronograph functions with thermal sensing capabilities. The T&R suffix denotes the specific tape and reel packaging format used for automated surface-mount assembly processes.
