Product details
Overview
TLC5930PWP from Texas Instruments is a 12-channel constant-current LED sink driver with 1024-step PWM grayscale control, 0.2–40 mA per channel adjustable via external IREF resistor, and DS-Link serial interface supporting up to 20 Mbps data rate in 24-pin HTSSOP (PWP) package. It enables high-fidelity full-color LED display systems requiring precise per-pixel brightness and color tone correction.
For engineers reviewing the TLC5930PWP datasheet, TLC5930PWP pinout, TLC5930PWP application, or TLC5930PWP equivalent, key selection considerations include its 10-bit grayscale resolution, triple-stage brightness adjustment (plane/frequency/dot), OVM fault detection, thermal error flag (TEF), and cascade-compatible DS-Link packet protocol for multi-device LED panel control.
Technical Context
The TLC5930PWP implements a 12-bit constant-current sink architecture with internal 1024-step PWM counter synchronized to GCLK (up to 25 MHz). Its DS-Link interface uses dual-wire packetized communication (DTIN/STIN → DTOUT/STOUT) with 2-bit pipeline delay and automatic ID handling for daisy-chained configurations.
It supports three independent brightness control layers: plane-level current scaling (64 steps), global frequency division (16 steps), and per-output dot correction (256 steps). Integrated features include OVM (open-LED detection), LED leakage detection (LKD), thermal error flag (TEF), and dual-source gray-scale clock (DSG) allowing switchable internal/external GCLK sourcing.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC5940PWP | 16-channel, 12-bit grayscale (4096 steps), no OVM or color tone correction; requires external VREF | Lacks integrated open-LED detection and per-pixel color tuning-less suitable for mission-critical signage | Choose when higher grayscale depth is prioritized over fault diagnostics and color fidelity |
| IS31FL3728-QFLS4-TR | 18-channel, I²C interface, auto-breathing, lower max current (28 mA), no DS-Link cascade | Designed for compact consumer lighting; lacks DS-Link scalability and industrial-grade fault reporting | Prefer for space-constrained designs with MCU I²C availability and no need for multi-hundred-node chaining |

FAQ
How does the TLC5930PWP achieve 1024-step grayscale control?
The TLC5930PWP uses an internal 10-bit PWM counter synchronized to the GCLK signal. Each output channel compares its 10-bit grayscale data value against this counter; when the count matches, the constant-current sink turns off. This generates precise duty cycles from 0/1024 to 1024/1024, enabling smooth intensity transitions. The TLC5930PWP supports both external GCLK (up to 25 MHz) and internally generated clock modes via the DSG function.
What is the role of the IREF pin on the TLC5930PWP?
The IREF pin on the TLC5930PWP sets the full-scale output current for all 12 channels. Connecting an external resistor between IREF and GND establishes a reference current (IIREF); the TLC5930PWP then delivers 168× that current to each OUTn pin (e.g., 5.1 kΩ yields ~40 mA). This single-resistor calibration ensures matched output currents across channels and simplifies BOM management in the TLC5930PWP design.
Can multiple TLC5930PWP devices be connected in series, and how does data propagation work?
Yes-the TLC5930PWP supports daisy-chained DS-Link topology using DTIN/STIN inputs and DTOUT/STOUT outputs. Data propagates with a fixed 2-bit pipeline delay: the output reflects input data two bit-times later. For N cascaded devices, the controller must send N×2 dummy bits after the final packet to ensure all devices complete latching. This deterministic timing enables synchronized grayscale updates across large LED arrays using the TLC5930PWP.
What fault detection features does the TLC5930PWP provide?
The TLC5930PWP integrates five hardware-monitored fault flags: OVM (open-LED detection), LKD (LED reverse leakage), TEF (thermal error at 150–170°C), GEF (gray-scale clock error), and HEF (HSYNC error). These are reported via dedicated pins or readable registers. For example, OVM monitors OUTn voltage during OFF periods to detect open circuits-critical for maintaining uptime in outdoor signage using the TLC5930PWP.
How does the TLC5930PWP handle brightness uniformity across LEDs with manufacturing variations?
The TLC5930PWP provides two calibration layers for brightness uniformity: dot correction (256-step per-output current scaling) and color tone correction (per-RGB sub-pixel current tuning). Dot correction compensates for LED forward-voltage and efficiency variances; color tone correction adjusts relative currents on OUT0–OUT2 (R), OUT3–OUT5 (G), etc., to correct chromaticity shifts. Both are programmed via dedicated DS-Link packets-enabling factory or field calibration of the TLC5930PWP in deployed systems.
