System Power-Up Sequence (continued)
Figure 36 shows the recommended DLPC900 system power-up sequence of the regulators:
Figure 36. Power Sequencing
9.3.1 Power-On Sense (POSENSE) Support
It is difficult to set up a power monitor to trip exactly on the controller minimum supply voltage specification. Thus
for practical reasons, the external power monitor generating POSENSE should target its threshold to 90% of the
minimum supply voltage specifications and ensure that POSENSE remains low a sufficient amount of time for all
supply voltages to reach minimum DLPC900 and DMD requirements and stabilize. The trip voltage for detecting
the loss of power, as well as the reaction time to respond to a low voltage condition is critical for powering down
the DMD. Refer to Power-Up and Power-Down Timing Requirements for details on powering up and powering
down the DLPC900 and the DMD.
9.3.2 Power Good (PWRGOOD) Support
The PWRGOOD signal is defined as an early warning signal that alerts the DLPC900 of the DC supply voltages
will drop below specifications. This warning lets the DLPC900 park the DMD mirrors and place the system into
reset. For revision "B" DMDs and later, PWRGOOD can no longer be used as an early warning signal, and must
follow the power-down requirements in Power-Up and Power-Down Timing Requirements.
9.3.3 5-V Tolerant Support
With the exception of USB_DAT, the DLPC900 does not support any other 5-V tolerant I/O. However, I2C
typically have 5V requirements and special measures must be taken to support them. It is recommended that a
5-V to 3.3-V level shifter be used.
