Product details
Overview
TLC69600RTWR from Texas Instruments is a 24-pin WQFN-packaged scan MOSFET controller designed for LCD local dimming backlight systems. It delivers 30mA maximum driving current at 20V sustaining voltage, supports daisy-chain interface up to 20MHz, and integrates ghost-cancellation and adaptive headroom voltage control for DC/DC optimization in TV and monitor backlight drivers.
For engineers reviewing the TLC69600RTWR datasheet, TLC69600RTWR pinout, TLC69600RTWR application, or TLC69600RTWR equivalent, this device is selected for high-precision LED scan control in multi-zone dimming architectures requiring thermal shutdown detection, UART/INT or SOUT/CLK_O readback, and programmable black insertion.
Technical Context
The TLC69600RTWR implements a 16-channel constant-current sink architecture synchronized with external TLC696x2/4/8 current-sink drivers to enable 2×, 4×, or 8× time-multiplexed scan control of P-MOSFETs. Its adaptive headroom scheme uses a single FB pin from the last device in the chain to regulate DC/DC output voltage, minimizing layout complexity.
It supports two diagnostic readback modes-UART + INT pin or dual-wire CLK_O/SOUT-and provides three error flags: LED open detection (LOD), LED short detection (LSD), and thermal shutdown detection (TSD). The device operates across 3V–5.5V VCC and interfaces with 1.8V/3.3V logic levels.
Key Specifications

Pinout & Package
Package: WQFN-24 (RTW), 4mm × 4mm body, 0.8mm max height, exposed thermal pad (Pin 25), RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Primary 3V–5.5V supply for internal logic and gate drivers; decoupling required near package. |
| GND | Ground reference | Common return path for logic, analog, and thermal pad; must be low-impedance connection to PCB ground plane. |
| CLK_I | Serial clock input | Accepts master clock for daisy-chain data synchronization; edge-triggered on rising edge. |
| SIN | Serial data input | Receives configuration and command data from upstream device or host controller. |
| SOUT | Serial data output | Drives downstream device in daisy chain; also used for diagnostic readback in CLK_O/SOUT mode. |
| CLK_O | Serial clock output | Passes synchronized clock to next device; doubles as diagnostic readback signal in dual-wire mode. |
| FB | Feedback input | Connects only to FB of final device in chain to regulate DC/DC output voltage via adaptive headroom control. |
| INT | Interrupt output | Active-low open-drain flag indicating LOD, LSD, or TSD event; requires external pull-up. |
| G0–G7 | Scan gate outputs | Drive gates of up to 8 external P-MOSFETs; each paired with D0–D7 current sinks in TLC696x2/4/8. |
| D0–D15 | Constant-current sink outputs | Not present on TLC69600RTWR - these are on companion TLC696x2/4/8 drivers; TLC69600RTWR controls their scan timing only. |
Key Features
| Feature | Design Value |
|---|---|
| Ghost-cancellation function | Eliminates upside ghosting artifacts in time-multiplexed local dimming by synchronizing scan transitions with current sink activation. |
| Adaptive headroom voltage control | Reduces power loss in DC/DC stage by dynamically adjusting output voltage to match minimum required LED forward voltage across active zones. |
| Programmable black insertion | Inserts controlled black frames between refresh cycles to reduce motion blur and improve perceived contrast in fast-moving video content. |
| Variable refresh rate (VRR) support | Enables flicker-free VRR operation by maintaining stable current regulation and timing alignment during dynamic frame-rate changes. |
| Minimum brightness update latency | Ensures rapid response to brightness commands - critical for HDR tone mapping and real-time dimming updates across hundreds of zones. |

FAQ
What is the primary function of the TLC69600RTWR in an LCD backlight system?
The TLC69600RTWR serves as a scan MOSFET controller that sequences gate signals for up to eight external P-MOSFETs, enabling time-multiplexed local dimming in conjunction with TLC696x2/4/8 current-sink drivers. It does not sink LED current itself but precisely times scan activation to minimize ghosting and optimize DC/DC headroom - a core function confirmed in the SNVSCJ8 datasheet for TLC69600RTWR.
Does the TLC69600RTWR integrate LED current regulation?
No, the TLC69600RTWR does not regulate LED current. It exclusively controls the gate timing of external P-MOSFETs used in scan rows. Constant-current sinking is handled by companion devices - TLC696x2/4/8 - which connect to D0–D15 outputs of those drivers. This functional separation is explicitly defined in the "Description" section of the TLC69600RTWR datasheet.
How does the adaptive headroom control work in the TLC69600RTWR?
The TLC69600RTWR implements adaptive headroom by using a single FB pin - connected only from the last device in a daisy chain - to sense the minimum required voltage across active LED strings. This feedback adjusts the DC/DC output to just exceed the highest forward voltage in the currently lit zones, reducing power loss and heat generation. The architecture is validated in the simplified schematic and description sections of the TLC69600RTWR datasheet.
What diagnostic capabilities does the TLC69600RTWR provide?
The TLC69600RTWR provides three hardware-detectable faults: LED open detection (LOD), LED short detection (LSD), and thermal shutdown detection (TSD). These are reported either via UART + INT pin or dual-wire CLK_O/SOUT outputs - selectable by register configuration. All three flags and both readback methods are documented in the "Diagnostics" subsection of the TLC69600RTWR feature list.
Is the TLC69600RTWR pin-compatible with other TLC696x0 variants like TLC69610RTWR?
Yes, the TLC69600RTWR shares identical WQFN-24 (RTW) package dimensions, pinout, and footprint with TLC69610RTWR, TLC69650RTWR, and TLC69660RTWR - as confirmed by TI's PACKAGE OPTION ADDENDUM and mechanical drawings. However, electrical parameters (drive current, sustaining voltage) differ, so validation of gate drive strength and voltage margin is required before substitution.
