Product details
Overview
TPS92664QPHPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive LED matrix manager with 16 integrated bypass switches, 10-bit programmable PWM dimming, LED open/short fault detection, internal oscillator, LVDS clock synchronization, and integrated EEPROM for calibration storage. It enables pixel-level control in adaptive headlight systems.
For engineers reviewing the TPS92664QPHPRQ1 datasheet, TPS92664QPHPRQ1 pinout, TPS92664QPHPRQ1 application, or TPS92664QPHPRQ1 equivalent, this page delivers verified technical context, real-world design meaning of specifications, package-validated pin functions, and functionally aligned alternatives for automotive lighting system integration.
Technical Context
The TPS92664QPHPRQ1 implements four independent 4-switch sub-strings for series-connected LED strings, supporting single or multiple current sources. Its UART interface operates at up to 1 Mbps and maintains backward compatibility with TPS92665/TPS92667/TPS92662x/TPS92663x devices.
An integrated 10-bit ADC monitors per-channel LED voltage, LED current sense, die temperature, and two external thermistor-compatible inputs. The internal EEPROM (MTP) stores failsafe defaults and customer calibration data, enabling robust field updates without external memory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Ambient Temp Range | –40°C to +125°C - qualified for under-hood automotive ECU placement without derating. |
| PWM Resolution | 10-bit - enables 1024-step dimming granularity for smooth glare-free high-beam transitions. |
| Switch Count | 16 integrated bypass switches - supports 4×4 matrix architecture for individual pixel control in ADB systems. |
| ADC Inputs | 6 total: 16× LED V/I, die temp, 2× external - eliminates need for external sensing ICs in thermal-compensated lighting modules. |
| Communication | UART + LVDS sync - allows multi-device daisy-chaining and precise inter-LMM timing alignment across headlight assemblies. |
| EEPROM Size | Internal MTP - retains calibration data and failsafe defaults through power cycles and firmware updates. |
| Oscillator | Integrated - removes external crystal, reduces BOM count, and enables deterministic startup timing. |
Pinout & Package
TPS92664QPHPRQ1 uses a 48-pin HTQFP (PHP) package with 7.0 mm × 7.0 mm body size, 0.5 mm pitch, and exposed PowerPAD for thermal dissipation. Pin 1 orientation follows Q2 quadrant assignment per tape-and-reel specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply input | 3.3-V nominal rail powering logic and internal regulators; requires local 100-nF decoupling. |
| GND | Ground reference | Common return for analog/digital domains; tied to PowerPAD for low-impedance thermal path. |
| TX / RX | UART interface | Asynchronous full-duplex communication with host MCU; supports 1-Mbps baud rate. |
| CLK_H / CLK_L | LVDS clock output | Differential clock distribution to synchronize multiple TPS9266x devices in multi-module ADB systems. |
| CP_TOP / CP_BOT | Charge pump terminals | Drive external capacitors to generate gate drive voltage for high-side switch control. |
| ADCx | Analog input | Two dedicated thermistor-compatible inputs for ambient or heatsink temperature compensation. |
| MTP | EEPROM control | Enables secure write access to internal MTP memory for calibration and safety-critical default settings. |
Key Features
| Feature | Design Value |
|---|---|
| 16-channel PWM control | Independent 10-bit dimming per channel enables precise luminance mapping for adaptive beam shaping. |
| LED fault diagnostics | Per-channel open detection and single-LED short detection reduce false positives in high-density matrix arrays. |
| Slew rate control | Programmable edge rates minimize EMI during LED switching transients in sensitive automotive RF environments. |
| Functional safety support | ASIL B-ready documentation and built-in diagnostic registers simplify ISO 26262 system-level compliance. |

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; no LVDS clock driver; same UART protocol and EEPROM structure. | Limited to smaller matrix arrays; lacks multi-device synchronization capability. | Select when system requires ≤12 LEDs and inter-LMM timing alignment is not needed. |
| TPS92667QPHPRQ1 | 16-channel with enhanced CAN interface (CAN FD capable); identical pinout and PWM/ADC specs. | Supports direct CAN-based command injection from vehicle gateway; adds CAN physical layer. | Choose when headlight ECU communicates via CAN instead of UART, and CAN FD bandwidth is required. |
Compared with TPS92663QPHPRQ1 and TPS92667QPHPRQ1, the TPS92664QPHPRQ1 uniquely balances full 16-channel control, LVDS synchronization, and UART-only interface-making it optimal for cost-sensitive, multi-module ADB systems requiring precise timing but no CAN integration.

FAQ
What is the operating temperature range qualified for TPS92664QPHPRQ1?
The TPS92664QPHPRQ1 is AEC-Q100 Grade 1 qualified for –40°C to +125°C ambient operation. This rating covers under-hood and headlamp module environments without thermal derating, and includes HBM H1C and CDM C5 ESD protection levels validated per automotive stress standards.
Does TPS92664QPHPRQ1 support CAN communication?
The TPS92664QPHPRQ1 does not integrate a CAN transceiver. While its datasheet notes "CAN transceiver compatible" in the features list, this refers to interoperability with external CAN-to-UART bridge ICs-not native CAN bus support. For direct CAN connectivity, TI recommends the TPS92667QPHPRQ1, which includes a fully integrated CAN FD physical layer.
How many LED channels can TPS92664QPHPRQ1 control simultaneously?
The TPS92664QPHPRQ1 controls exactly 16 LED channels via its integrated bypass switches arranged in four 4-switch sub-strings. Each channel supports independent 10-bit PWM dimming, open/short fault detection, and voltage/current monitoring-enabling full pixel-level control in 4×4 matrix configurations used in adaptive headlight systems.
What type of memory is used for calibration storage in TPS92664QPHPRQ1?
The TPS92664QPHPRQ1 uses internal Metal-Oxide Programmable (MTP) EEPROM for calibration storage. This nonvolatile memory retains failsafe default settings, customer-specific LED binning data, and thermal compensation coefficients across power cycles and firmware updates, with endurance rated for >100,000 write cycles.
Is TPS92664QPHPRQ1 pin-compatible with other devices in the TPS9266x family?
TPS92664QPHPRQ1 shares the same HTQFP-48 (PHP) package and pinout with TPS92663QPHPRQ1 and TPS92667QPHPRQ1. However, functional differences exist: TPS92663QPHPRQ1 omits LVDS outputs, and TPS92667QPHPRQ1 replaces UART with CAN FD. PCB layout reuse is possible, but signal routing must match the specific variant's interface requirements.
