ZHCSD19A September 2014 – October 2015 DLP9000
PRODUCTION DATA.
The following power supplies are all required to operate the DMD: VCC, VCCI, VOFFSET, VBIAS, and VRESET. VSS must also be connected. DMD power-up and power-down sequencing is strictly controlled by the DLPC900 or DLPC910 Controllers within their associated reference designs.
CAUTION
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. VCC, VCCI, VOFFSET, VBIAS, and VRESET 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 will result in a significant reduction in the DMD’s reliability and lifetime. Refer to Figure 19.
PARAMETER | MIN | MAX | UNIT | |
---|---|---|---|---|
VBIAS | Supply voltage level during power–down sequence | 4.0 | V | |
VOFFSET | 4.0 | V | ||
VRESET | –4.0 | 0.5 | V |
