The chipset consists of three components—the DLP4620S-Q1 automotive DMD, the DLPC231S-Q1, and the TPS99000S-Q1. The DMD is a light modulator consisting of tiny mirrors that are used to form and project images. The DLPC231S-Q1 is a controller for the DMD; it formats incoming video and controls the timing of the DMD illumination sources and the DMD in order to display the incoming video. The TPS99000S-Q1 is a high-performance voltage regulator for the DMD, a controller for the illumination sources (for example, LEDs or lasers), and a management IC for the entire chipset. In conjunction, the DLPC231S-Q1 and the TPS99000S-Q1 can be used for system-level monitoring, diagnostics, and failure detection features. Figure 7-1 is a system-level block diagram with these devices in the DLP head-up display configuration and displays the primary features and functions of each device.
