The document describes the features, applications, and functions of RHB DAP www.ti.com. It is a 16-channel LED driver with dot correction, suitable for monocolor, multicolor, and full-color LED displays as well as LED backlighting applications. The driver provides high-precision constant-current output and can be controlled via a serial data interface.
The TLC5923 is a 16‑channel constant‑current sink LED driver with dot‑correction capability. Each channel can be individually programmed for on/off control and brightness adjustment, and the device includes error detection for LED open and thermal conditions.
Key features include 0‑80 mA drive capability, 30 MHz serial data transfer, 7‑bit (128‑step) dot‑correction, and support for both HTSSOP (PowerPAD) and QFN packages. The datasheet details electrical characteristics, recommended operating conditions, pin functions, and thermal‑pad information.
