MAX6604AATA+T

MAX6604AATA+T is a high-precision temperature sensor designed for thermal monitoring functions in DDR memory modules. This device is readable and programmable through the 2-wire SMBus/I²C-compatible interface. Three address inputs set the bus address for the temperature sensor to provide upto eight devices on one bus. The internal thermal sensor continuously monitors the temperature and updates the temperature data eight times per second. The host can read the temperature data at any time. Since the thermal sensor is located on the memory module, the temperature data recorded accurately represents the temperature of the components on the module. Consequently, this device provides a much more accurate measurement of module temperature than techniques involving temperature sensors on the motherboard. It is used in applications such as memory modules, desktop computers, notebook computers, workstations, and networking equipment.
