9.3 DMD Power Supply Power-Down Procedure

  • During power-down, VDD must be supplied until after VBIAS, VRESET, and VOFFSET are discharged to within the specified limit of ground. See Section 9.1.
  • During power-down, it is a strict requirement that the voltage difference between VBIAS and VOFFSET must be within the specified limit shown in Section 6.4.
  • During power-down, there is no requirement for the relative timing of VRESET with respect to VBIAS.
  • Power supply slew rates during power-down are flexible, provided that the transient voltage levels follow the requirements specified in Section 6.1, in Section 6.4, and in Figure 9-1.
  • During power-down, LVCMOS input pins must be less than specified in Section 6.4.
A. See the Pin Functions table.
B. To prevent excess current, the supply voltage difference |VBIAS – VOFFSET| must be less than the specified limit in Section 6.4.
C. To prevent excess current, the supply difference |VBIAS – VRESET| must be less than the specified limit in Section 6.4.
D. VBIAS must power up after VOFFSET has powered up, per tDELAY1 specification in Section 9.1.
E. VRESET, VOFFSET and VBIAS ramps must start after VDD and VDDA are powered up and stable.
F. After the DMD micromirror park sequence is complete, the DLP controller software initiates a hardware power-down that activates DMD_EN_ARSTZ and disables VBIAS, VRESET and VOFFSET.
G. Under power-loss conditions where emergency DMD micromirror park procedures are being enacted by the DLP controller hardware DMD_EN_ARSTZ goes low.
H. VDD must remain powered on and stable until after VOFFSET, VBIAS, and VRESET are powered off, per tDELAY3 specification in Section 9.1.
I. To prevent excess current, the supply voltage delta |VDDA – VDD| must be less than specified limit in Section 6.4.
J. Not to scale. Details omitted for clarity.
