8.2 Typical Application

The DLPA300 micromirror driver controls the switching of the bias, offset and reset voltage levels on the MBRST pins to assure correct DMD operation. It is a controlled by a DLP display controller which synchronizes the display data sent to the DMD with the correct sequencing of the bias, offset and reset voltage levels by the DLPA300 micromirror driver. The typical application shown in Figure 8-1 is a Full-HD display using the DLP780NE chipset. The application is the same for the DLP800RE, DLP781NE or DLP801RE/DLPC4430 chipsets and the DLP780TE, DLP781TE or DLP801XE/dual-DLPC4420 chipsets. The DLPA300 micromirror driver creates VBIAS and VOFFSET with internal voltage regulators. VRESET is created by an external regulator. These voltages are switched by the DLPA300 micromirror driver on the OUT[0:14] pins which are connected to the MBRST pins on the DMD.
