9.3 Power Supply Sequencing Requirements

A. Refer to Table 9-1 and Figure 9-2 for critical power-up sequence delay requirements.
B. To prevent excess current, the supply voltage delta |VBIAS – VOFFSET| must be less than specified in Section 6.4. OEMs may find that the most reliable way to ensure this is to power VOFFSET prior to VBIAS during power-up and to remove VBIAS prior to VOFFSET during power-down. Refer to Table 9-1 and Figure 9-2 for power-up delay requirements.
C. To prevent excess current, the supply voltage delta |VBIAS – VRESET| must be less than the specified limit shown in Section 6.4.
D. When system power is interrupted, the DLPA2000/2005/3000 initiates hardware power-down that disables VBIAS, VRESET and VOFFSET after the micromirror park sequence.
E. Drawing is not to scale and details are omitted for clarity.
