Product details
Overview
TLC69610QRTWRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive scan MOSFET controller designed for local dimming backlight systems, supporting up to 1024 cascaded devices, delivering 60mA per channel at up to 20V, and operating from 3V to 5.5V supply voltage in automotive display applications.
For engineers reviewing the TLC69610QRTWRQ1 datasheet, TLC69610QRTWRQ1 pinout, TLC69610QRTWRQ1 application, or TLC69610QRTWRQ1 equivalent, this page delivers verified technical context, validated package mapping (WQFN-24), confirmed daisy-chain interface specs (20MHz, 1.8V/3.3V I/O), thermal shutdown diagnostics, and real-world automotive LCD dimming use cases.
Technical Context
The TLC69610QRTWRQ1 implements adaptive headroom voltage control to directly regulate DC/DC converters via a single FB pin from the last device in a serial chain, minimizing layout complexity. It integrates ghost-cancellation circuitry to eliminate upside ghosting in time-multiplexed LED arrays.
It supports two programmable diagnostic readback modes-UART/INT and two-wire CLK_O/SOUT-and provides three error flags: LED open detection (LOD), LED short detection (LSD), and thermal shutdown detection (TSD), enabling robust system-level fault monitoring in automotive displays.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar scan MOSFET controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC69610QPWPRQ1 | HTSSOP-28 package (9.7mm × 4.4mm), MSL Level-3, thermal pad not wettable flank | Preferred where board space allows larger footprint and thermal vias are feasible; less suitable for ultra-thin automotive modules | Select when legacy HTSSOP layout reuse or higher thermal mass is prioritized over miniaturization. |
| TLC69660QRTWRQ1 | Same WQFN-24 package but rated for 60mA/50V output; higher voltage headroom | Required for LED strings exceeding 20V (e.g., >8 white LEDs), not needed for standard 5-LED clusters | Choose only if system-level LED forward voltage exceeds 20V; otherwise, TLC69610QRTWRQ1 offers optimal cost/performance balance. |
Compared with TLC69610QPWPRQ1 and TLC69660QRTWRQ1, the TLC69610QRTWRQ1 uniquely balances compact wettable-flank packaging, 20V/60mA capability, and automotive-grade diagnostics-making it the optimal choice for space-constrained, thermally demanding central display and cluster applications.

FAQ
What is the maximum number of TLC69610QRTWRQ1 devices that can be cascaded in a daisy chain?
The TLC69610QRTWRQ1 supports up to 1024 devices in a single daisy chain, enabling full-array local dimming control across large-format automotive displays with fine-grained zone resolution. This scalability is achieved through deterministic timing and low-latency serial interface design, and is explicitly validated in TI's application documentation for the TLC696x0-Q1 family.
Does the TLC69610QRTWRQ1 support both UART and two-wire diagnostic readback simultaneously?
No - the TLC69610QRTWRQ1 supports UART/INT or CLK_O/SOUT diagnostic readback, selected via register configuration; both modes are not active concurrently. The selection determines whether fault flags (LOD/LSD/TSD) are reported over UART or encoded on the two-wire synchronous interface, allowing system designers to match host controller interface capabilities.
What is the purpose of the FB pin on the TLC69610QRTWRQ1, and how should it be connected?
The FB pin on the TLC69610QRTWRQ1 is used exclusively for adaptive headroom voltage control: only the FB pin of the last device in the daisy chain must be connected to the DC/DC converter feedback node. This simplifies PCB layout and ensures optimal efficiency by regulating output voltage precisely to the highest-forward-voltage LED string in the chain.
Is the thermal pad (pin 25) of the TLC69610QRTWRQ1 electrically connected internally?
No - the exposed thermal pad (pin 25) on the TLC69610QRTWRQ1 is not electrically connected to any internal circuit; it serves solely for mechanical attachment and thermal dissipation. TI's datasheet and land pattern guidelines require it to be soldered to a dedicated PCB copper pour tied to GND for optimal thermal performance and reliability.
How does the ghost-cancellation function in the TLC69610QRTWRQ1 improve display quality?
The ghost-cancellation function in the TLC69610QRTWRQ1 actively suppresses residual charge buildup in time-multiplexed LED scanning, eliminating "upside ghosting" - a visual artifact where lit segments appear faintly in adjacent rows. This is implemented in hardware and requires no external components or firmware intervention, directly enhancing contrast and readability in automotive LCD backlights.
