7.3.6 Temperature Sensing Diode

The DMD includes a temperature sensing diode designed to be used with the TMP411-Q1 temperature monitoring device. The DLP products controller may monitor the DMD array temperature via the TMP411-Q1 and temperature sense diode.

Figure 7-1 shows the typical connection between the DLP products controller, TMP411-Q1, and the DLP3021-Q1 DMD. The signals to the temperature sense diode are sensitive to system noise, and care should be taken in the routing and implementation of this circuit. See the TMP411-Q1 data sheet for detailed PCB layout recommendations.

It is recommended that the host controller manage parking of the DMD based on the allowable temperature specifications and temperature measurements.
