Product details
Overview
TPS92667QPHPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive LED matrix manager IC with 16 integrated bypass switches, 10-bit programmable PWM dimming, and built-in LED open/short fault detection - deployed in adaptive driving beam (ADB) headlight systems requiring pixel-level control and functional safety compliance.
For engineers reviewing the TPS92667QPHPRQ1 datasheet, TPS92667QPHPRQ1 pinout, TPS92667QPHPRQ1 application, or TPS92667QPHPRQ1 equivalent, this page delivers verified technical context, UART/LVDS interface behavior, diagnostic register mapping, HTQFP-48 package layout, and validated alternative options for automotive lighting system design.
Technical Context
The TPS92667QPHPRQ1 implements a 4×4 matrix of series-connected integrated switches enabling individual LED pixel control per sub-string, with internal low-noise LVDS clock receiver synchronized to external TPS92664/TPS92665 system clocks. It supports multi-drop UART communication compatible with prior LMM generations and CAN transceivers.
Diagnostic capability includes real-time reporting of LED open faults, short faults, and functional parameters via dedicated registers; phase shift and pulse width per LED are independently programmable, supporting glare-free high-beam and sequential DRL animation without external microcontroller intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED matrix management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS92663QPHPRQ1 | 12-channel version with identical UART/LVDS interface and diagnostic register set; lacks 4 bypass switches. | Suitable for smaller LED matrices (e.g., 3×4), not scalable to full 4×4 ADB layouts. | Select when fewer LEDs reduce cost and thermal load without compromising diagnostic or timing features. |
| TPS92665QPHPRQ1 | Includes integrated boost controller and higher-current switches (1.2 A vs. 0.8 A); same pinout and register map. | Supports direct LED string drive without external buck/boost stage - increases integration but raises thermal density. | Choose when system requires higher per-channel current and board space is constrained; verify thermal margin with PowerPAD layout. |
Compared with TPS92667QPHPRQ1, the TPS92663QPHPRQ1 offers reduced channel count at lower cost for entry-level ADB, while the TPS92665QPHPRQ1 adds integrated power conversion for simplified bill-of-materials - both retain UART compatibility and functional safety documentation support.

FAQ
What is the primary function of the TPS92667QPHPRQ1 in automotive lighting systems?
The TPS92667QPHPRQ1 serves as a 16-channel LED matrix manager that enables pixel-level control of individual LEDs in adaptive driving beam (ADB) and glare-free high-beam systems. It integrates bypass switches, 10-bit PWM dimming, slew rate control, and real-time open/short fault detection - all within a single AEC-Q100 Grade 1 qualified device. Its UART and LVDS interfaces allow seamless integration into vehicle lighting ECUs without requiring additional timing or communication peripherals.
Does the TPS92667QPHPRQ1 require external current sources or can it drive LEDs directly?
The TPS92667QPHPRQ1 does not include integrated current regulation and requires external constant-current sources (e.g., buck or boost LED drivers) to supply the LED strings. It functions as a bypass switch controller - routing current around individual LEDs in each of four 4-LED sub-strings - rather than as a current source itself. This architecture allows flexible pairing with TI's TPS92664 or TPS92665 for complete ADB subsystems.
How does the TPS92667QPHPRQ1 support functional safety requirements in automotive applications?
The TPS92667QPHPRQ1 is designated Functional Safety-Capable, with documentation provided to support ISO 26262 ASIL-B system-level development. It includes diagnostic registers for LED open/short detection, internal register checksums, and fault-reporting mechanisms accessible via UART. While it does not achieve ASIL-B by itself, its architecture and safety manual enable integration into ASIL-B-compliant lighting control units when combined with appropriate system-level monitoring and redundancy.
What package type and thermal characteristics does the TPS92667QPHPRQ1 use?
The TPS92667QPHPRQ1 uses a 48-pin PowerPAD HTQFP (PHP) package measuring 7.0 mm × 7.0 mm with 0.5 mm pitch and a maximum height of 1.2 mm. Its exposed thermal pad must be soldered to a PCB copper area with thermal vias for effective heat dissipation - critical for sustained operation in high-brightness ADB applications. The package is rated MSL Level-3 and supports peak reflow at 260°C.
Is the TPS92667QPHPRQ1 pin-compatible with earlier devices in the LMM family?
Yes, the TPS92667QPHPRQ1 shares the same HTQFP-48 PHP package footprint and pinout as TPS92663QPHPRQ1 and TPS92665QPHPRQ1, enabling hardware reuse across different channel-count and feature variants. UART register maps and diagnostic reporting structures are also aligned, simplifying firmware migration between models in the same LMM generation.
