Product details
Overview
TPS92663QPWPTQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive LED matrix manager IC for adaptive headlight systems, featuring six integrated bypass switches (two sub-strings of three series switches), 4.5 V to 60 V input range, programmable 10-bit PWM dimming with device-to-device synchronization, and on-chip 8-bit ADC with two MUX inputs for LED binning and temperature compensation.
For engineers reviewing the TPS92663QPWPTQ1 datasheet, TPS92663QPWPTQ1 pinout, TPS92663QPWPTQ1 application, or TPS92663QPWPTQ1 equivalent, key selection considerations include its UART/CAN-physical-layer interface compatibility, open/short LED fault reporting, slew-rate-controlled PWM switching for EMI mitigation, and HTSSOP-24 package with PowerPAD for thermal management in high-brightness LED matrix control.
Technical Context
The TPS92663QPWPTQ1 implements a multi-drop UART interface with CAN-compatible physical layer support, enabling robust communication across up to 16 daisy-chained devices on a single bus alongside TPS92662-Q1. Its internal charge pump supplies gate drive voltage for low-RDS(on) bypass switches rated for ≤20 V across switch and ≤62 V from switch to GND.
Each of the six bypass switches supports individual phase-shifted and pulse-width-programmable 10-bit PWM dimming, synchronized across multiple devices via register-controlled timing alignment. The integrated 8-bit ADC measures two multiplexed inputs-typically used for system temperature sensing and LED bin-code reading-to enable closed-loop brightness calibration and thermal derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 60 V - supports direct connection to automotive battery rail including cold-crank and load-dump transients. |
| Bypass Switch Count | 6 switches in two independent 3-switch sub-strings - enables pixel-level LED bypass for ADB/Glare-Free High Beam patterns. |
| PWM Resolution & Control | 10-bit programmable dimming with per-LED phase shift and pulse width - allows fine-grained intensity and timing control per matrix element. |
| ADC Capability | 8-bit with 2-channel MUX - provides real-time binning value readback and temperature compensation without external sensors. |
| Communication Interface | Multi-drop UART with CAN PHY compatibility - reduces harness wiring count while maintaining noise immunity in ECU environments. |
| Fault Detection | Programmable open-LED and short-LED detection - reports faults via serial interface for system-level diagnostics and fail-safe response. |
| Thermal Rating | AEC-Q100 Grade 1 (–40°C to +125°C ambient) - qualified for under-hood ECU placement in automotive headlight modules. |
Pinout & Package
TPS92663QPWPTQ1 uses a thermally enhanced 24-pin HTSSOP (PWP) package with exposed PowerPAD (7.70 mm × 4.40 mm body size, 0.65 mm pitch), optimized for high-current LED driver thermal dissipation in compact headlight ECU layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| VDD | Digital core supply | 3.3 V internal LDO output; powers logic, UART, ADC, and control registers. |
| GND | Analog/digital ground | Common reference for all circuits; tied to PowerPAD for low-impedance thermal and electrical path. |
| TX / RX | UART serial interface | Half-duplex UART pins compatible with external CAN transceivers for noise-immune bus communication. |
| CANH / CANL | CAN physical layer I/O | Direct connection points for external CAN transceiver; not internal CAN controller - requires external PHY. |
| LED1–LED6 | Bypass switch terminals | Source/drain connections for six integrated N-channel MOSFETs; each controls one LED segment in matrix string. |
| XTALI / XTALO | Clock oscillator interface | Drives external crystal (typically 1–4 MHz) for precise PWM timing and UART baud rate generation. |
| ADCIN1 / ADCIN2 | Analog MUX inputs | Two dedicated analog inputs for binning code reading and temperature sensor voltage measurement. |
| CPP1–CPP6 | Charge pump outputs | Internal charge pump rails supplying boosted gate voltage to respective bypass switches for full enhancement. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED matrix management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS92662QPWPRQ1 | Same pinout and UART/CAN PHY interface; lacks internal crystal oscillator driver and second ADC input. | Designed for simpler matrix topologies without on-module binning or standalone clocking; lower BOM cost where external crystal not required. | Select when system already provides stable clock source and binning compensation is handled externally. |
| MAX20052ATP/V+T | 4-channel LED controller with integrated boost converter; no bypass switches or UART/CAN interface; uses SPI. | Targets smaller LED arrays (≤4 strings); integrates power conversion but lacks pixel-level bypass capability and multi-drop communication. | Select for cost-sensitive, non-ADB applications requiring integrated power stage and minimal external components. |
Compared with TPS92663QPWPTQ1, the TPS92662QPWPRQ1 offers identical communication and switching architecture but omits crystal drive and dual ADC functionality - suitable for streamlined ADB implementations. The MAX20052ATP/V+T provides integrated power conversion but cannot replace pixel-level matrix control, making it appropriate only for fixed-pattern LED drivers without adaptive capability.

FAQ
What is the maximum number of TPS92663QPWPTQ1 devices supported on a single UART bus?
The TPS92663QPWPTQ1 supports up to 16 addressable devices on a single multi-drop UART bus. Each device is assigned a unique 4-bit address via external resistors or configuration pins, enabling centralized control of large LED matrices across multiple headlamp modules without additional MCU resources or complex routing.
Does the TPS92663QPWPTQ1 integrate a CAN controller or require an external transceiver?
The TPS92663QPWPTQ1 does not include an integrated CAN controller. It provides CAN-physical-layer-compatible signal levels on its CANH/CANL pins and requires an external CAN transceiver (e.g., TCAN1042-Q1) to interface with a CAN network. Its UART interface remains the primary command channel, with CAN used solely for robust physical layer transmission.
How does the TPS92663QPWPTQ1 handle LED open-circuit faults?
The TPS92663QPWPTQ1 continuously monitors each of its six LED channels for open-circuit conditions using internal comparators with programmable thresholds. Upon detection, it flags the fault in a dedicated status register and reports it via the UART interface - enabling immediate system-level response such as pattern recalibration or warning message generation in the vehicle dashboard.
Can the TPS92663QPWPTQ1 operate without an external crystal?
No - the TPS92663QPWPTQ1 requires an external crystal connected between XTALI and XTALO pins (typically 1–4 MHz) to generate its internal clock for PWM timing and UART baud rate accuracy. The device includes a crystal oscillator driver circuit but no internal RC oscillator; operation without a crystal is not supported.
What thermal management features does the TPS92663QPWPTQ1 package provide?
The TPS92663QPWPTQ1 uses an HTSSOP-24 (PWP) package with an exposed PowerPAD thermal pad. When soldered to a properly designed PCB copper pour, this pad conducts heat from the internal power switches directly to the board, enabling sustained operation at full load in ambient temperatures up to +125°C - critical for under-hood automotive headlight ECU placement.
