8.3.5 Temperature Monitor Function

The DLPC120-Q1 connects with the TMP411 through a standard I2C bus protocol using the TMP_SDA and TMP_SCL pins. The internal temperature controller initializes the TMP411 to read the temperature of the DMD.

The TMP controller issues a set of read commands at eight times per second through the I2C interface to read the remote temperature (DMD) and local temperature from the TMP411.

The TMP411 monitors the DMD temperature and controls the DMD park operation when the DMD is operated beyond the required specification. See the DLP3030-Q1, DLP3020-Q1 and DLP3021-Q1 Data Sheet for the DMD operating temperature. If the DMD park operation is used, then a 1-degree hysteresis is applied. See the DLPC120-Q1 Programmer's Guide for description of this function.
