DLP5531AAFYSQ1

Specialized ICS Overview

The DLP5531A-Q1 is a 0.55-inch automotive Digital Micromirror Device (DMD) featuring a 1.3-megapixel array with a 2:1 aspect ratio. It comprises 1152 columns by 1152 rows of micromirrors with a 7.6-μm diagonal pitch and ±12° tilt angle. The device operates within an array temperature range of -40°C to +105°C and utilizes bottom illumination for optical efficiency. It interfaces via a 600-MHz Sub-LVDS bus and supports a 10-kHz refresh rate. The component is housed in a 149-pin CPGA package and requires the DLPC230-Q1 controller and TPS99001-Q1 system management IC for operation.

Specialized ICS Feature Summary

• Automotive-grade qualification with -40°C to +105°C operating temperature range
• 1.3-MP resolution (1152x1152) configured in a 2:1 aspect ratio
• 600-MHz Sub-LVDS interface enabling <100 µs full array update times
• Bottom illumination design supporting compact optical engine packaging

Specialized ICS Applications

• High-resolution adaptive driving beam headlights
• LIDAR optical filtering systems

Specialized ICS Procurement Notes

Verify that the complete chipset includes the DLPC230-Q1 controller and TPS99001-Q1 system management IC, as the DMD requires these specific components for reliable function. Confirm AEC-Q100 qualification status and ensure thermal management solutions maintain the array temperature within the specified -40°C to +105°C operational limits during high-load conditions.

Specialized ICS Selection Notes

Select this device for applications requiring wide aspect ratio projection and high resolution in exterior lighting. Ensure the optical system supports bottom illumination geometry. Verify compatibility with the required 1.8-V logic supplies (VDD/VDDI) and high-voltage mirror bias levels (VBIAS/VOFFSET/VRESET). Consider the 10-border micromirror Pond of Micromirrors (POM) when designing active image boundaries.

Specialized ICS Part Context

This component belongs to the DLP5531-Q1 automotive chipset series designed specifically for exterior lighting. It succeeds previous automotive DMDs like the DLP3030-Q1, offering more than three times the optical throughput. The device is part of Texas Instruments' DLP technology portfolio tailored for safety-critical automotive environments.

Specialized ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The DLP5531A-Q1 is specified to be used exclusively with the DLPC230-Q1 and TPS99001-Q1 controllers; alternative DMDs may require different control architectures.
