9.3 Power Supply Sequencing Requirements

(1)

Refer to Table 3 and Figure 23 for critical power-up sequence delay requirements.

(2)

To prevent excess current, the supply voltage delta |VBIAS – VOFFSET| must be less than specified in

Recommended Operating Conditions. 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 3 and

Figure 23 for power-up delay requirements.

(3)

To prevent excess current, the supply voltage delta |VBIAS – VRESET| must be less than specified limit shown in

Recommended Operating Conditions.

(4)

When system power is interrupted, the DLPA3000/DLPA3005 initiates hardware power-down that disables VBIAS,

VRESET and VOFFSET after the Micromirror Park Sequence.
