LM86CIMMX Datasheet

±0.75˚C Accurate, Remote Diode and Local Digital Temperature Sensor with Two-Wire Interface


General Description
The LM86 is an 11-bit digital temperature sensor with a 2-wire System Management Bus (SMBus) serial interface. The LM86 accurately measures its own temperature as well as the temperature of an external device, such as processor thermal diode or diode connected transistor such as the 2N3904. The temperature of any ASIC can be accurately determined using the LM86 as long as a dedicated diode (semiconductor junction) is available on the target die.

■ 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

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