LM95214 Overview
The LM95214 device is an 11-bit digital temperature sensor with a 2-wire System Management Bus (SMBus) interface that can very accurately monitor the temperature of four remote diodes as well as its own temperature. The four remote diodes can be external devices such as microprocessors, graphics processors that target the ideality of a 2N3904 transistor or diode-connected 2N3904s. Two LM95214 remote temperature channels have programmable digital filters while the other two remote channels use a fault-queue to minimize unwanted TCRIT events when temperature spikes are encountered. For optimum flexibility and accuracy, each LM95214 channel includes registers for offset correction. A three-level address pin allows connection of up to 3 LM95214s to the same SMBus master. The LM95214 includes power saving functions such as: programmable conversion rate, shutdown mode, and disabling of unused...
