C8724QP

The C8724 is a driver IC supporting up to an 8×12 LED matrix. 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 2-bit address decoding configuration, allowing up to 4 ICs to be connected in parallel on a single data bus, significantly reducing the performance requirements on the MCU. 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℃.
