The BM82D8032-1 is a DALI dimming module compliant with the DALI-2 specification[cite: 1]. It communicates with the host via the DALI bus and converts DALI commands into PWM outputs for the DALI LED driver, realizing switch, dimming, scene, group, and addressing functions[cite: 1]. With its compact package size, it easily integrates with LED driver PCBAs[cite: 1]. Powered by a Holtek 32-bit MCU with built-in 128KB Flash, it supports secondary development[cite: 1]. By connecting external resistors to the Iset pin, it perfectly accommodates constant current drivers requiring different output currents, making it ideal for DALI constant voltage/constant current drivers[cite: 1].
