When the ALERT pin is cleared, the above cycle repeats, with the ALERT pin becoming active when the

temperature equals or exceeds T(HIGH). The ALERT pin can also be cleared by resetting the device with the

general-call Reset command. This action also clears the state of the internal registers in the device, returning the

device to comparator mode (TM = 0).

Both operating modes are represented in Figure 7-9 and Figure 7-10. Table 7-12 and Table 7-13 list the format

for the THIGH and TLOW registers. The most significant byte is sent first, followed by the least significant byte. The

power-up reset values for T(HIGH) and T(LOW) are:

• THIGH = +80°C

• TLOW = +75°C

The format of the data for THIGH and TLOW is the same as for the Temperature Register.

8 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification, and

TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining

suitability of components for their purposes. Customers should validate and test their design

implementation to confirm system functionality.

8.1 Application Information

The TMP112 family is used to measure the PCB temperature of the board location where the device is mounted.

The programmable address options allow up to four locations on the board to be monitored on a single serial

bus.
