The following power supplies are all required to operate the DMD: VCC, VCCI, and VCC2. VSS must also be connected. DMD power-up and power-down sequencing is strictly controlled by the DLPC4430 display controller.
Note: For reliable operation of the DMD, the following power supply sequencing requirements must be followed. Failure to adhere to the prescribed power-up and power-down procedures may affect device reliability. V
CC, V
CCI and V
CC2 power supplies have to be coordinated during power-up and power-down operations. V
SS must also be connected. Failure to meet any of the below requirements results in a significant reduction in the reliability and lifetime of the DMD. Refer to
Figure 9-1.
