Product details
Overview
TLC69610YBHR from Texas Instruments is a 24-pin DSBGA scan MOSFET controller designed for LCD local dimming backlight systems, delivering 60mA sustaining current at 20V per channel, supporting daisy-chain interface up to 20MHz, and integrating thermal shutdown detection and UART/INT diagnostics. It pairs with TLC696x2/4/8 current-sink drivers to enable 2×/4×/8× time-multiplexed control of up to 8 scan MOSFETs in TV, monitor, and notebook displays.
For engineers reviewing the TLC69610YBHR datasheet, TLC69610YBHR pinout, TLC69610YBHR application, or TLC69610YBHR equivalent, key selection criteria include its 60mA/20V P-MOSFET drive capability, programmable black insertion and VRR support, ghost-cancellation function, adaptive headroom voltage control for DC/DC optimization, and dual diagnostic readback options (UART/INT or SOUT/CLK_O).
Technical Context
The TLC69610YBHR implements a serial daisy-chain interface with 1.8V/3.3V I/O compatibility and 20MHz maximum data rate, enabling high-speed configuration and status reporting across multi-device chains. Its architecture integrates 16 constant-current sinks and supports global + individual 8-bit current programming for precise LED current control.
It features adaptive headroom voltage control that simplifies system layout by requiring FB connection only from the last device in the chain to regulate DC/DC output. Diagnostic functions include LED open (LOD), LED short (LSD), and thermal shutdown (TSD) detection, with two configurable readback paths: UART + INT pin or two-wire CLK_O/SOUT.

Equivalent & Alternatives
The following parts are listed as comparable options for similar scan MOSFET controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC69610RTWR | Same electrical specs but in 4mm × 4mm WQFN-24 package with NIPDAU finish and different thermal pad layout. | Better suited for manual rework or thermal-intensive designs due to larger exposed pad and higher thermal mass. | Select when board-level thermal management or hand-soldering feasibility is prioritized over footprint size. |
| TLC69660YBHR | Higher 60mA/50V drive rating; identical pinout, package, and feature set otherwise. | Required for systems using higher-VLED rails (>20V) or demanding enhanced voltage margin in industrial displays. | Choose only if 50V sustaining voltage is needed; not drop-in compatible for 20V-only designs due to over-spec voltage handling. |
Compared with TLC69610YBHR, TLC69610RTWR offers superior thermal dissipation in WQFN but occupies 4× more board area, while TLC69660YBHR provides extended voltage headroom at identical footprint-neither is pin-compatible with automotive-Q1 variants nor supports direct substitution without validation of voltage and thermal constraints.

FAQ
What is the primary function of the TLC69610YBHR in an LCD backlight system?
The TLC69610YBHR serves as a scan MOSFET controller that coordinates high-side P-MOSFET switching for time-multiplexed local dimming zones. It interfaces with TLC696x2/4/8 current-sink drivers to manage up to 8 scan lines, providing 60mA/20V drive capability, ghost cancellation, and adaptive headroom control. Its role is critical for synchronizing LED current regulation with row-select timing in the TLC69610YBHR-based backlight architecture.
Does the TLC69610YBHR support daisy-chaining, and what is the maximum data rate?
Yes, the TLC69610YBHR supports high-speed daisy-chaining via dedicated CLK_I, SIN, SOUT, and CLK_O pins. It operates at up to 20MHz data transfer rate with 1.8V/3.3V I/O compatibility, enabling rapid configuration and diagnostic readback across multi-device chains. This capability is essential for scaling local dimming zones without adding host GPIO overhead, and the TLC69610YBHR maintains timing integrity across all linked devices.
How does the adaptive headroom voltage control work in the TLC69610YBHR?
The TLC69610YBHR implements adaptive headroom voltage control by monitoring sink current demand and dynamically adjusting the VLED rail via feedback to the DC/DC converter. Only the FB pin of the last device in the daisy chain must be connected to the DC/DC, simplifying routing and reducing component count. This scheme minimizes power loss across the current sinks and improves overall system efficiency-key for thermal-constrained designs using the TLC69610YBHR.
What diagnostic features does the TLC69610YBHR provide, and how are they accessed?
The TLC69610YBHR provides three hardware diagnostics: LED open detection (LOD), LED short detection (LSD), and thermal shutdown detection (TSD). These are reported either through UART + INT pin (active-low interrupt) or two-wire CLK_O/SOUT outputs-configurable via register. The choice allows flexibility depending on host processor resources; both methods deliver real-time fault visibility without requiring additional communication peripherals in the TLC69610YBHR implementation.
Is the TLC69610YBHR pin-compatible with other members of the TLC696x0 family?
Yes, the TLC69610YBHR shares identical pinout and package dimensions (DSBGA-24, YBH) with TLC69600YBHR, TLC69650YBHR, and TLC69660YBHR. However, drive specifications differ: TLC69610YBHR delivers 60mA/20V, while TLC69660YBHR supports 60mA/50V. Electrical substitution requires verification of voltage margin and thermal performance-TLC69610YBHR is not functionally interchangeable with higher-voltage variants without system-level validation.
