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 |V_BIAS – V_OFFSET| must be less than specified in Recommended Operating Conditions. OEMs may find that the most reliable way to ensure this is to power V_OFFSET prior to V_BIAS during power-up and to remove V_BIAS prior to V_OFFSET 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 |V_BIAS – V_RESET| must be less than specified limit shown in Section 6.4.

D. When system power is interrupted, the DLPA3000/DLPA3005 initiates hardware power-down that disables V_BIAS, V_RESET and V_OFFSET after the Micromirror Park Sequence.

E. Drawing is not to scale and details are omitted for clarity.

Table 9-1 Power-Up Sequence Delay Requirement

PARAMETER		MIN	MAX	UNIT
t_DELAY	Delay requirement from V_OFFSET power up to V_BIAS power up	2		ms
V_OFFSET	Supply voltage level at beginning of power–up sequence delay (see Figure 9-2)		6	V
V_BIAS	Supply voltage level at end of power–up sequence delay (see Figure 9-2)		6	V

Refer to Table 9-1 for V_OFFSET and V_BIAS supply voltage levels during power-up sequence delay.
