资 源 简 介

The LM84 is a remote diode temperature sensor,Delta-Sigma analog-to-digital converter, and digitalover-temperature detector with an SMBus™ interface. TheLM84 senses its own temperature as well as the temperatureof 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. Ahost can query the LM84 at any time to read the temperatureof this diode as well as the temperature state of the LM84itself. A T_CRIT_A interrupt output becomes active when thetemperature is greater than a programmable comparatorlimit, T_CRIT.
