DS1629集成电路（IC）的热管理规格书PDF中文资料

DESCRIPTION

The DS1629 2-Wire Digital Thermometer and Real Time Clock integrates the critical functions of a real time clock and a temperature monitor in a small outline 8-pin SOIC package. Communication to the DS1629 is accomplished via a 2-wire interface. The wide power supply range and minimal power requirement of the DS1629 allow for accurate time/temperature measurements in battery-powered applications.

FEATURES

Measures temperatures from -55°C to +125°C; Fahrenheit equivalent is -67°F to 257°F

Real time clock counts seconds, minutes, hours, date of the month, month, day of the week, and year with leap year compensation through the year 2100

Thermometer accuracy is ±2.0°C (typ)

Thermometer resolution is 9 bits (expandable)

Thermostatic and time alarm settings are user definable. Dedicated open-drain Alarm output

32 bytes SRAM for general data storage

Data is read from/written to via a 2-wire serial interface. (open drain I/O lines)

Wide power supply range (2.2V - 5.5V)

Applications include personal computers/PDAs, cellular telephones, office equipment, dataloggers, or any thermally sensitive system
