Figure 14. DMD Power Supply Requirements
1. See Recommended Operating Conditions, Pin Functions.
2. To prevent excess current, the supply voltage delta |VCCI – VCC| must be less than specified limit in
Recommended Operating Conditions.
3. To prevent excess current, the supply voltage delta |VBIAS – VOFFSET| must be less than specified in
Recommended Operating Conditions.
4. To prevent excess current, the supply voltage delta |VBIAS – VRESET| must be less than specified limit in
Recommended Operating Conditions.
5. VBIAS should power up after VOFFSET has powered up, per the Delay1 specification in Table 10.
6. PG_OFFSET should turn off after EN_OFFSET has turned off, per the Delay2 specification in Table 10.
