PRODUCTION DATA
The following power supplies are all required to operate the DMD: VDD, VDDI, and VCC2. VSS must also be connected. DMD power-up and power-down sequencing is strictly controlled by the DLPC4420 display controller.
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. VDD, VDDI and VCC2 power supplies have to be coordinated during power-up and power-down operations. VSS 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.
