Figure 9-1. DMD Power Supply Requirements

A. See Section 6.4, and the Pin Functions Table 5-1.

B. To prevent excess current, the supply voltage difference |VOFFSET – VBIAS| must be less than the specified limit in the Section 6.4

C. To prevent excess current, the supply difference |VBIAS – VRESET| must be less than the specified limit in the Section 6.4.

D. VBIAS must power up after VOFFSET has powered up, per the Delay1 specification in Table 9-1

E. PG_OFFSET must turn off after EN_OFFSET has turned off, per the Delay2 specification in Table 9-1

high.

PWRDNZ and disables VBIAS, VRESET, and VOFFSET.

I.

EN_OFFSET may turn off after PG_OFFSET has turned off. The OEZ signal goes high prior to PG_OFFSET turning off to indicate the

DMD micromirror has completed the emergency park procedures.
