Description
The LM89 is an 11-bit digital temperature sensor with a 2-wire System Management Bus (SMBus) serial interface. The LM89 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 LM89EVAL is the evaluation board for the LM89
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
