Introduction

C8624 is an LED matrix driver IC supporting up to 8×11 LEDs. Each LED can be independently controlled with 8-bit PWM data and 256-level linear PWM dimming. The IC features a built-in 64-level global current adjustment function. It supports 1-bit address decoding, allowing up to 2 ICs to be connected in parallel on a single data bus, significantly reducing MCU performance requirements. The operating voltage range is 2.9V~5.5V with ultra-low operating current, down to 250μA in sleep mode. The IC is available in QSOP24 or QFN24 packages, with an operating temperature range of -40℃~85℃.
