ME7502C is a constant current LED driver chip based on I2C communication, featuring 32-step constant current global adjustment. It consists of 12 segment outputs and 8 grid outputs, forming a 96-dot matrix, with each dot supporting 256-level PWM duty cycle adjustment. Integrating a data latch, display memory, LED constant current drive module and related control circuits, it serves as a high-reliability MCU peripheral LED drive circuit. Serial data is input to ME7502C via a two-wire interface, packaged in SSOP24 (e=0.635, D=1.45). The product is reliable, stable and anti-interference, mainly suitable for LED drive scenarios such as household appliances, vacuum cleaners, speakers and portable devices.
