Texas Instruments TLC5923 16‑Channel LED Driver Datasheet
The TLC5923 is a 16‑channel constant‑current sink driver designed for LED display and lighting applications. Each channel can be turned on/off and individually adjusted with 7‑bit dot‑correction (128 steps) via a serial data interface. The device also includes LED open detection (LOD) and a thermal error flag (TEF) for fault monitoring.
The datasheet provides detailed electrical characteristics, recommended operating conditions, package options (32‑pin HTSSOP with PowerPAD™ and 32‑pin QFN), and mechanical dimensions. It also describes the serial interface timing, pin functions, and switching characteristics needed for system integration.
