Each output channel has an independent PWM brightness register; a single I²C write can update all eight channels simultaneously. The datasheet provides the register map and the sequence for configuring output state, dimming, and group dimming modes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/PCA9634D118","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/PCA9634D118 when reusing this data.
