A. DLP controller and PMIC controls start of DMD operation
B. Mirror park sequence starts
C. Mirror park sequence ends. DLP controller and PMIC disables VBIAS, VOFFSET, and VRESET.
D. Power off.
E. Refer to Table 9-1 and Figure 9-2 for critical power-up sequence delay requirements.
F. When system power is interrupted, the ASIC driver initiates hardware the power-down sequence, that disables VBIAS, VRESET and VOFFSET after the micromirror park sequence is complete. Software the power-down sequence, disables VBIAS, VRESET, and VOFFSET after the micromirror park sequence through software control.
G. To prevent excess current, the supply voltage delta |VBIAS – VRESET| must be less than specified limit shown in Section 6.4.
H. Drawing is not to scale and details are omitted for clarity.
