19-3837; Rev 0; 10/05 Precision Temperature Monitor for DDR Memory Modules MAX6604 General Description Features The MAX6604 high-precision temperature sensor is JEDEC Compliant designed for thermal monitoring functions in DDR memo- ±1°C Temperature-Monitoring Accuracy ry modules. The device is readable and programmablethrough the 2-wire SMBusTM/I2C-compatible interface. Overtemperature Interrupt with Programmable Three address inputs set the bus address for the temper- Threshold ature sensor to provide up to eight devices on one bus. +2.7V to +3.6V Operating Voltage Range The internal thermal sensor continuously monitors the SMBus/I2C-Compatible Interface temperature and updates the temperature data eight 300µA Typical Operating Current times per second. The master can read the tempera-ture data at any time. Since the thermal sensor is locat- 3µA Typical Shutdown Current ed on the memory module, temperature data recorded -20°C to +125°C Operating Temperature Range accurately represents the temperature of the compo- 8-Pin TSSOP and TDFN (MO-229-WCED-2) nents on the module. Consequently, the MAX6604 pro- Packages vides a much more accurate measurement of moduletemperature than techniques involving temperature Ordering Information sensors on the motherboard. In addition, the deviceresponds more quickly to temperature changes on the PKG module than a motherboard sensor. PART TEMP RANGE PIN-PACKAGE CODE The MAX6604 also features an interrupt-output indica- 8 TDFN-EP** tor for temperature-threshold monitoring. The threshold MAX6604ATA -20°C to +125°C T823-1 (MO229-WCED-2) levels are programmable through the digital interface. MAX6604AHA -20°C to +125°C 8 TSSOP H8-1 The MAX6604 operates from -20°C to +125°C, and isavailable in JEDEC-standard 8-pin TSSOP and TDFN **EP = Exposed paddle. (MO-229-WCED-2) packages.
