DLP4500 Présentation
A digital micromirror device (DMD) is an array of microscopic mirrors that reflect light to create patterns or images. Each mirror represents one pixel and can be tilted between two states to modulate light. DMDs are the core of DLP projection technology and are used in spatial light modulation for structured light, 3D scanning, and optical patterning. The DLP4500 is a WXGA (912 × 1140) array, offering high resolution in a compact form factor.
Key features include a 912 × 1140 micromirror array, 7.6-µm mirror pitch, ±12° tilt angle, and support for a 30-bit parallel RGB interface for image data transfers. The device operates with a DLPC350 controller and requires proper generation of PWRGOOD and POSENSE inputs for reliable operation. The DLP4500 is available in a 98-pin LCCC package (20.7 × 9.1 mm) and is designed for visible light applications.
The DLP4500 uses a MEMS (micro-electromechanical systems) architecture where each micromirror is electrostatically actuated. The mirrors are arranged in a 912 × 1140 array with a uniform band of border micromirrors that are not user-addressable. The device supports high-speed pattern rates, making it suitable for applications requiring fast light modulation. The DLPC350 controller generates internal mirror reset pulses, ensuring precise timing.
Typical applications include 3D scanning and measurement, structured light for machine vision, augmented reality, and optical patterning. The DLP4500 is also used in medical imaging and spectroscopy. Its high resolution and fast switching make it ideal for industrial and scientific applications where precise light control is essential.
When designing with the DLP4500, ensure proper thermal management and signal integrity. The device requires a clean power supply and careful PCB layout to minimize noise. The DLPC350 controller must be configured correctly to achieve optimal performance.

Notes de conception
The DLP4500 requires multiple power rails with specific sequencing. Ensure PWRGOOD and POSENSE signals are properly generated to avoid unreliable operation. Use low-noise LDOs for analog supplies and decouple each rail with 100nF and 10uF capacitors close to the pins.
The DLP4500 dissipates heat through the LCCC package. Provide adequate thermal vias and a copper pour on the PCB to keep the device within operating temperature. For high pattern rates, consider active cooling to prevent overheating.
Route the 30-bit parallel RGB interface with matched trace lengths to maintain signal integrity. Keep high-speed signals away from the micromirror array to avoid interference. Follow the layout guidelines in the TI datasheet for optimal performance.
