    Products Detail

    The LM89 is a digital temperature sensor that accurately measures its own temperature and the temperature of an external device (such as a processor thermal diode or diode-connected transistor) via a two-wire SMBus interface. It features an offset register for sensing a variety of thermal diodes, on-board local temperature sensing, and a 10-bit plus sign remote diode temperature data format with 0.125°C resolution. The device provides T_CRIT_A output for system shutdown and ALERT output supporting SMBus 2.0 protocol. It is compatible with SMBus 2.0 and supports TIMEOUT. The LM89 is available in 8-pin MSOP and SOIC packages.

    Key Features

    • Accurately senses die temperature of remote ICs or diode junctions
    • Offset register allows sensing a variety of thermal diodes accurately
    • On-board local temperature sensing
    • 10-bit plus sign remote diode temperature data format, 0.125°C resolution
    • T_CRIT_A output useful for system shutdown
    • ALERT output supports SMBus 2.0 protocol
    • SMBus 2.0 compatible interface, supports TIMEOUT
    • 8-pin MSOP and SOIC packages

    Application scenarios

    • Processor/Computer System Thermal Management (e.g. Laptop, Desktop, Workstations, Server)
    • Electronic Test Equipment
    • Office Electronics
