7.3.6 Temperature Sensing Diode

The DMD includes a temperature sensing diode designed to be used with the TMP411-Q1 or equivalent temperature monitoring device.

Figure 7-1 shows the typical connection between the DLP products controller, TMP411-Q1, and the DLP2021-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.

Figure 7-1 Temperature Sense Diode Typical Circuit Configuration

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