Product details
Overview
TLC69600QRTWRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive scan MOSFET controller for local dimming backlight systems, integrating 16 constant-current sinks and supporting up to 1024-device daisy chains. It delivers 30mA per channel at 20V, operates from 3V–5.5V VCC, and features UART/INT and SOUT/CLK_O diagnostic readback for LCD displays in automotive cluster and HUD applications.
For engineers reviewing the TLC69600QRTWRQ1 datasheet, TLC69600QRTWRQ1 pinout, TLC69600QRTWRQ1 application, or TLC69600QRTWRQ1 equivalent, key selection factors include its 24-pin WQFN wettable flank package, ghost-cancellation function, adaptive headroom voltage control for DC/DC optimization, and support for black insertion and VRR display enhancement features.
Technical Context
The TLC69600QRTWRQ1 implements a time-multiplexed scan architecture compatible with TLC696x2/4/8-Q1 current-sink drivers to enable 2×, 4×, or 8× multiplexing. It integrates on-chip thermal shutdown detection and three error flags: LED open (LOD), LED short (LSD), and TSD.
Its high-speed daisy chain interface supports up to 20MHz data transfer with 1.8V/3.3V I/O compatibility and programmable drive strength for EMI reduction. The device uses adaptive headroom control-only the FB pin of the last device in the chain connects to the DC/DC converter-to simplify layout and improve system efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 3V to 5.5V - enables direct integration with common automotive 3.3V or 5V supply rails without level-shifting. |
| Channel Current | 30mA @ 20V - supports driving P-MOSFETs for local dimming zones in mid-voltage automotive LCD backlights. |
| Daisy Chain Speed | Up to 20MHz - allows rapid configuration and status readback across large cascaded arrays (≤1024 devices). |
| Diagnostic Outputs | UART + INT pin or CLK_O + SOUT - provides flexible, register-programmable fault reporting for LOD, LSD, and TSD. |
| Operating Temp | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and instrument cluster environments. |
| ESD Rating | HBM Level 2 (±2kV), CDM Level C4B (±1.5kV) - ensures robustness during board handling and in-vehicle ESD events. |
| Ghost Cancellation | Integrated hardware function - eliminates upside ghosting artifacts in time-multiplexed scanning topologies. |
Pinout & Package
Package: 24-pin WQFN (RTW) with wettable flank, 4mm × 4mm body, 0.5mm pitch, exposed thermal pad (pin 25), and JEDEC MO-220 compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary power return and signal reference; multiple pins (e.g., pins 1, 12, 13, 24) ensure low-impedance path for sink currents and noise immunity. |
| VCC | Supply input | 3V–5.5V logic and internal circuitry supply; decoupling required near pin 2 and pin 23 per layout guidelines. |
| CLK_I / CLK_O | Clock input/output | Asynchronous daisy-chain clock distribution: CLK_I receives master clock; CLK_O drives next device in chain. |
| SIN / SOUT | Serial data in/out | Unidirectional daisy-chain data path: SIN accepts configuration/status from upstream; SOUT forwards downstream. |
| FB | Feedback input | Analog input for adaptive headroom control; only the final device's FB connects to DC/DC converter output. |
| INT | Interrupt output | Open-drain active-low flag indicating LOD, LSD, or TSD event; requires external pull-up for UART/INT mode. |
| NC | No connect | Pins 6, 7, 18, 19 are reserved and must remain unconnected per datasheet; not internally bonded. |
Key Features
| Feature | Design Value |
|---|---|
| Full-array local dimming topology | Supports up to 1024 cascaded devices for fine-grained zone control in large-format automotive displays. |
| Adaptive headroom voltage control | Reduces power loss by dynamically adjusting DC/DC output based on real-time LED forward voltage demands. |
| Minimum brightness update latency | Enables fast frame-rate transitions without visible flicker or brightness lag in dynamic content rendering. |
| Black insertion & VRR support | Improves motion clarity and reduces blur via synchronized blanking intervals and variable refresh rate alignment. |
| Programmable interface drive strength | Adjusts daisy-chain signal slew rate to suppress radiated emissions without sacrificing timing margins. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar scan MOSFET controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC69610QRTWRQ1 | 60mA channel current rating (vs. 30mA), same 20V max, identical pinout and protocol. | Better suited for higher-brightness zones or longer LED strings requiring greater sink current. | Select when design requires >30mA per channel; otherwise, TLC69600QRTWRQ1 offers optimal cost/power trade-off. |
| TLC69650QRTWRQ1 | 30mA channel current but rated for 50V operation (vs. 20V); shares same WQFN-24 package and interface. | Required for high-VF LED stacks or designs needing wider voltage margin in harsh automotive transients. | Choose only if system VLED exceeds 20V; otherwise, TLC69600QRTWRQ1 provides tighter voltage tolerance and lower leakage. |
Compared with TLC69610QRTWRQ1 and TLC69650QRTWRQ1, the TLC69600QRTWRQ1 delivers optimized performance for standard 20V automotive LED backlighting-balancing thermal efficiency, package size, and functional safety diagnostics without over-specifying voltage or current capability.

FAQ
What is the maximum number of TLC69600QRTWRQ1 devices that can be daisy-chained?
The TLC69600QRTWRQ1 supports cascading up to 1024 devices in a single daisy chain, enabling scalable local dimming control for large-area automotive displays. This capacity is achieved through its high-speed 20MHz serial interface and dedicated CLK_O/SOUT outputs, with timing integrity maintained across the full chain per TI's layout and termination guidelines.
Does TLC69600QRTWRQ1 require external current-setting resistors?
No, the TLC69600QRTWRQ1 does not require external current-setting resistors. It implements two digital current control layers: an 8-bit global Maximum Current (MC) setting and individual 8-bit Channel Current (CC) settings, both configured via its serial interface-eliminating component count and calibration drift associated with analog resistor networks.
How does the ghost-cancellation function in TLC69600QRTWRQ1 work?
The TLC69600QRTWRQ1 integrates dedicated hardware-based ghost-cancellation logic that detects and suppresses residual charge buildup during time-multiplexed scanning, specifically eliminating "upside ghosting" artifacts. This function operates autonomously without firmware intervention and is enabled by default per the device's internal scan timing engine.
What diagnostic error flags does TLC69600QRTWRQ1 report?
The TLC69600QRTWRQ1 reports three distinct hardware-monitored faults: LED Open Detection (LOD), LED Short Detection (LSD), and Thermal Shutdown Detection (TSD). These flags are accessible via either UART/INT mode (serial command + interrupt assertion) or SOUT/CLK_O mode (two-wire status shift-out), both programmable through configuration registers.
Is the thermal pad (pin 25) of TLC69600QRTWRQ1 electrically connected?
Yes, the exposed thermal pad (pin 25) of the TLC69600QRTWRQ1 is electrically connected to GND and must be soldered to a PCB thermal plane for both mechanical stability and thermal performance. TI specifies this connection as mandatory-not optional-in all layout examples and thermal design notes for the RTW package.
