TMP105 SLLS648D – FEBRUARY 2005 – REVISED SEPTEMBER 2011 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure.

TMP105 SLLS648D – FEBRUARY 2005 – REVISED SEPTEMBER 2011 www.ti.com APPLICATIONS INFORMATION The TMP105 is a digital temperature sensor that is optimal for thermal management and thermal protection applications. The TMP105 is Two-Wire and SMBus interface-compatible, and is specified over a temperature range of –40°C to +125°C. The TMP105 requires no external components for operation except for pull-up resistors on SCL, SDA, and ALERT, although a 0.1μF bypass capacitor is recommended, as shown in Figure 1.

TMP105 SLLS648D – FEBRUARY 2005 – REVISED SEPTEMBER 2011 www.ti.com CONFIGURATION REGISTER The Configuration Register is an 8-bit read/write register used to store bits that control the operational modes of the temperature sensor. Read/write operations are performed MSB first. The format of the Configuration register for the TMP105 is shown in Table 6, followed by a breakdown of the register bits. The power-up/reset value of the Configuration Register is all bits equal to 0. Table 6.

TMP105 SLLS648D – FEBRUARY 2005 – REVISED SEPTEMBER 2011 www.ti.com FAULT QUEUE (F1/F0) A fault condition is defined as when the measured temperature exceeds the user-defined limits set in the THIGH and TLOW Registers. Additionally, the number of fault conditions required to generate an alert may be programmed using the fault queue. The fault queue is provided to prevent a false alert as a result of environmental noise.

TMP105 SLLS648D – FEBRUARY 2005 – REVISED SEPTEMBER 2011 www.ti.com Both operational modes are represented in Figure 3. Table 9 and Table 10 describe the format for the THIGH and TLOW Registers. Note that the most significant byte is sent first, followed by the least significant byte. Power-up reset values for THIGH and TLOW are: THIGH = 80°C and TLOW = 75°C The format of the data for THIGH and TLOW is the same as for the Temperature Register. Table 9.

TMP105 SLLS648D – FEBRUARY 2005 – REVISED SEPTEMBER 2011 www.ti.com BUS OVERVIEW The device that initiates the transfer is called a master, and the devices controlled by the master are slaves. The bus must be controlled by a master device that generates the serial clock (SCL), controls the bus access, and generates the START and STOP conditions. To address a specific device, a START condition is initiated, indicated by pulling the data-line (SDA) from a HIGH to LOW logic level while SCL is HIGH.
PAGE 11
TMP105 www.ti.com SLLS648D – FEBRUARY 2005 – REVISED SEPTEMBER 2011 SMBus ALERT FUNCTION The TMP105 supports the SMBus Alert function. When the TMP105 is operating in Interrupt Mode (TM = 1), the ALERT pin of the TMP105 may be connected as an SMBus Alert signal. When a master senses that an ALERT condition is present on the ALERT line, the master sends an SMBus Alert command (00011001) on the bus.
