Product Introduction

Overview

The LED2472GQTR, produced by STMicroelectronics, is a monolithic, low voltage, low current power 24-bit shift register specifically designed for LED panel displays. It is tailored for both indoor and outdoor LED screen billboards. The device features 24 constant current output channels, divided into three groups (red, green, and blue) of 8 independently-controlled channels. Each channel's current can be regulated within a range of 4 mA to 72 mA, adjustable in 64 steps of resolution. The LED2472GQTR also includes advanced features such as LED failure detection, auto power shutdown, and thermal management with overtemperature flags and output thermal shutdown at 170 °C.
