JAJSAR0B March 2007 – October 2017 LM95214
PRODUCTION DATA.
The LM95214 operates only as a slave device and communicates with the host through the SMBus serial interface essentially compatible with I2C. SMBCLK is the clock input pin, SMBDATA is a bidirectional data pin, and TCRIT1, TCRIT2, TCRIT3 are the output pins. The LM95214 requires a pullup resistor on the SMBCLK, SMBDATA, and TCRIT1, TCRIT2, TCRIT3 pins due to an open-drain output. It is very important to consider the pullup resistor for the I2C systems. The recommended value for the pullup resistors is in Figure 25. Use a ceramic capacitor type with a temperature rating from –40°C to +125°C, placed as close as possible to the VDD pin of the LM95214. The decoupling capacitor reduces any noise induced by the system. A0 (pin 6) can be connected to either Low, Mid-Supply or High voltages for address selection for configuring three possible unique slave ID addresses; SMBus Interface explains the addressing scheme.
