    EMC1438 1В°C Multiple Temperature Sensor
    with Hardware Controlled Standby &
    Hottest of Multiple Zones
    PRODUCT FEATURES Datasheet General Description Features The EMC1438 is a high accuracy, low cost, System
    Management Bus (SMBus) temperature sensor.
    Advanced features such as Resistance Error Correction
    (REC), Beta Compensation (to CPU diodes requiring the
    BJT or transistor model) and automatic diode type
    detection combine to provide a robust solution for
    complex environmental monitoring applications.
    Additionally, the hardware controlled STANDBY pin
    allows for system level power shutdown to support
    energy saving initiatives. В„ Hardware Set Standby Mode В„ Designed to support 45nm, 65nm, and 90nm CPU
    diodes
    Supports diodes requiring the BJT or transistor model
    Resistance Error Correction (up to 100 Ohms)
    Up to seven External Temperature Monitors The EMC1438 monitors up to eight temperature
    channels (up to seven external and one internal). The
    device provides В±1В°C accuracy for the internal and
    external diode temperatures.
    Temperature monitoring includes two tiers of protection:
    one that can be masked and causes the ALERT pin to
    be asserted, and the other that cannot be masked and ...
