TI 德州仪器 电子元器件分类

具有 SMBus 和 I2C 接口的 ±1°C 远程和本地温度传感器

The is a remote diode temperature sensor, Delta-Sigma analog-to-digital converter, and digital over-temperature detector with an SMBus™ interface. The LM84 senses its own temperature as well as the temperature of a target IC with a diode junction, such as a Pentium® II processor or a diode connected 2N3904. A diode junction semiconductor junction is required on the target IC"s die. A host can query the LM84 at any time to read the temperature of this diode as well as the temperature state of the LM84 itself. A T_CRIT_A# interrupt output becomes active when the temperature is greater than a programmable comparator limit, T_CRIT.

The host can program as well as read back the state of the T_CRIT register. Three state logic inputs allow two pins ADD0, ADD1 to select up to 9 SMBus address locations for the LM84. The sensor powers up with default thresholds of 127°C for T_CRIT.
