Pulldown resistors are required on the pins in the below table to avoid a floating input during the power-up and power-down conditions.

(1) If these pins are not connected to the DLPC23xS-Q1 (as in a headlight configuration), then they may be tied directly to ground without a pulldown resistor.
(2) Resistor pulldowns are required to create a minimum load for DMD_VOFFSET, DMD_VBIAS, and DMD_VRESET. Each of these pulldowns should provide a load from 0.1mA to 1mA. If the –8V LDO is used, then the pulldown for DMD_VRESET may be eliminated. If only one or zero TIAs are used, then these pulldowns may draw up to 1mA of current.
