    Thermal Shutdown PRODUCT FEATURES Datasheet General Description Applications The EMC2112 is an SMBus, closed-loop, RPM-based
    fan driver with hardware (HW) thermal shutdown and
    reset controller. The EMC2112 offers a single High Side
    fan driver capable of sourcing up to 600mA from a 5V
    supply. „ The EMC2112 utilizes Beta Compensation (an
    implementation of the BJT or transistor model for
    thermal diodes) and Resistance Error Correction (REC)
    to accurately monitor up to three (3) external
    temperature zones. These features allow great accuracy
    for CPU substrate thermal diodes on multiple process
    geometries as well as with discrete diode-connected
    transistors. Both Beta Compensation and REC can be
    disabled on the EMC2112 to maintain accuracy when
    monitoring AMD thermal diodes. „ „
    „ Features The EMC2112 also provides 5V supply ‘power good’
    function with a threshold of 4.5V. This function is
    provided on the RESET pin. 1% accuracy with external clock input
    3% accuracy with internal clock
    Internal clock can be used as a source
