Texas Instruments DLP472TPFQY

Overview

DLP472TPFQY from Texas Instruments is a 0.47-inch diagonal digital micromirror device (DMD) enabling 4K UHD (3840 × 2160) projection with ±17° micromirror tilt, 5.4 µm mirror pitch, and bottom illumination architecture - deployed in compact mobile smart TVs and portable projectors requiring high-resolution spatial light modulation.

For engineers reviewing the DLP472TPFQY datasheet, DLP472TPFQY pinout, DLP472TPFQY application, or DLP472TPFQY equivalent, this page delivers verified electrical specs (VBIAS = –14 V, VOFFSET = 10 V), thermal limits (TARRAY ≤ 70°C), SubLVDS interface timing (720 MHz clock), and chipset integration guidance with DLPC8445 and DLPA3085.

Technical Context

The DLP472TPFQY implements a MEMS-based spatial light modulator with four independent SubLVDS data lanes (A–D), each carrying 8-bit differential pairs plus dedicated differential clocks, supporting 4K UHD at 60 Hz or 1080p at 240 Hz. Its optical architecture relies on precise HVCMOS-level voltage control (VOFFSET, VBIAS, VRESET) to drive micromirror electrostatic actuation.

Thermal management centers on micromirror array temperature calculation using TP1 test point and 1.2 °C/W thermal resistance; illumination must stay within ILLVIS ≤ 20.5 W/cm² and marginal ray angle ≤ 55° to avoid lifetime degradation. The device requires coordinated power sequencing across five supplies and uses an integrated temperature diode (TEMP_P/TEMP_N) for closed-loop thermal monitoring.

FAQ

What is the primary function of the DLP472TPFQY in a display system?

The DLP472TPFQY serves as a digitally controlled MEMS spatial light modulator that converts digital video data into visible light patterns using an array of 3840 × 2160 microscopic mirrors. Each mirror in the DLP472TPFQY tilts ±17° to reflect or block light, enabling high-contrast 4K UHD projection. It operates exclusively as part of the TI DLP 0.47-inch 4K chipset with DLPC8445 and DLPA3085.

Which power supplies are mandatory for DLP472TPFQY operation?

Five power supplies are mandatory for DLP472TPFQY operation: VDD (1.8 V core logic), VDDI (1.8 V SubLVDS receivers), VOFFSET (10 V HVCMOS logic), VBIAS (–14 V mirror electrode), and VRESET (–14 V reset signal). All VSS ground connections are also required. Failure to meet |VBIAS – VOFFSET| ≤ 10.5 V or |VBIAS – VRESET| ≤ 33 V risks permanent damage to the DLP472TPFQY.

How does the DLP472TPFQY handle thermal management during continuous operation?

The DLP472TPFQY uses a calculated micromirror array temperature derived from ceramic test point TP1 and a documented 1.2 °C/W thermal resistance. Long-term operation requires TARRAY ≤ 70°C, enforced via illumination limits (ILLVIS ≤ 20.5 W/cm²) and marginal ray angle ≤ 55°. The integrated TEMP_P/TEMP_N diode enables real-time thermal feedback to the DLPC8445 controller for dynamic brightness or frame-rate throttling.

Can the DLP472TPFQY be used without the DLPC8445 display controller?

No - the DLP472TPFQY is not a standalone display IC and cannot operate without the DLPC8445 display controller. The DLP472TPFQY lacks internal frame memory, timing generation, or video decoding; it accepts only serialized SubLVDS image data and command sequences generated exclusively by the DLPC8445. TI specifies no alternative controller compatibility for the DLP472TPFQY.

What is the significance of the FQY package designation for DLP472TPFQY?

The FQY package identifies the DLP472TPFQY as a 166-pin LGA (land grid array) with 163 functional pads, measuring 24.50 mm × 11.00 mm, designed for bottom-side optical illumination and direct thermal coupling to heatsinks. This package is mechanically and electrically unique to the 0.47-inch DLP chipset and is not interchangeable with other DLP device packages such as FQL or FQM - confirming the DLP472TPFQY's role in ultra-compact 4K optical engines.
