DLP4500FQD

Specialized ICS Overview

The DLP4500FQD is a digital micromirror device (DMD) featuring a 0.45-inch diagonal micromirror array with 912 × 1140 resolution, exceeding one million individually addressable mirrors. It utilizes a 7.6-µm pitch and ±12° tilt angle with a 5-µs crossover time. The FQD package provides a 98-pin LCCC form factor measuring 9.1 mm × 20.7 mm, incorporating an enhanced thermal interface area of 7 mm × 7 mm for improved heat dissipation compared to the standard connector-only variant. Designed as a spatial light modulator, it steers visible light with high efficiency and precision.

Specialized ICS Feature Summary

• Diamond array orientation supports side illumination for simplified optical designs
• Window transmission efficiency of 96% nominal across 420 to 700 nm wavelengths
• Polarization-independent aluminum micromirrors with a 92% nominal fill factor
• Integrated micromirror driver circuitry requiring dedicated DLPC350 controller

Specialized ICS Applications

• Machine vision including 3-D depth measurement and robotic guidance
• Medical instruments such as 3-D dental scanners and vascular imaging
• 3-D biometrics for fingerprint identification and facial recognition
• Virtual gauges, augmented reality, interactive displays, and microscopes

Specialized ICS Procurement Notes

Verify that the specific ordering suffix matches the required package type. The FQD designation indicates the 98-pin LCCC package with an enhanced thermal interface, distinct from the FQE variant which lacks this thermal pad. Confirm compatibility with the DLPC350 chipset for reliable operation. Ensure handling procedures meet ESD requirements, specifically the ±2000 V human-body model rating.

Specialized ICS Selection Notes

Select the DLP4500FQD when active thermal management is critical due to high incident light energy or dense packaging constraints. The enhanced thermal interface allows for higher operational reliability under demanding duty cycles compared to the FQE package. Ensure the system design accommodates the 98-pin LCCC footprint and provides necessary power supplies: VCC, VREF, VOFFSET, VBIAS, and VRESET.

Specialized ICS Part Context

The DLP4500 series includes variants like the DLP4500AFQE and DLP4500NIRAFQD. The FQD suffix specifically denotes the 98-pin LCCC package with a 7 mm × 7 mm thermal interface area, whereas the FQE suffix denotes an 80-pin LCCC package without the thermal pad. Both are part of the same DLP chipset ecosystem requiring compatible controllers.
