9 Power Supply Recommendations

The following power supplies are all required to operate the DMD:

VSS
VCC
VCCI
VBIAS
VOFFSET
VRESET

DMD power-up and power-down sequencing is very important. Sequencing is controlled by the DLPC900 Controller and through the DMD power supply design.

CAUTION:

For reliable operation of the DMD, the following power supply sequencing requirements must be followed. Failure to adhere to any of the prescribed power-up and power-down requirements may affect device reliability. See Figure 9-1 in Section 9.2.

VBIAS, VCC, VCCI, VOFFSET, and VRESET power supplies must be coordinated during power-up and power-down operations. Failure to meet any of the below requirements results in a significant reduction in the DMD reliability and lifetime. Common ground VSS must also be connected.
