MAX6604AAHA+

The MAX6604AAHA+ is a high precision temperature monitor for DDR memory module in 8 pin TSSOP package. Three address inputs set the bus address for the temperature sensor to provide up to eight devices on one bus. The internal thermal sensor continuously monitors temperature and updates temperature data eight times per second. The master can read the temperature data at any time. Since thermal sensor is located on the memory module, temperature data recorded accurately represents the temperature of components on the module. Consequently, the MAX6604 provides a much more accurate measurement of module temperature than techniques involving temperature sensors on motherboard. In addition, it responds more quickly to temperature changes on module than a motherboard sensor. The threshold levels are programmable through digital interface. It is used in memory modules, desktop and notebook computers, workstations and networking equipment.
