The DS2484 is an I2C-to-1-Wire® bridge device that interfaces directly to standard (100kHz max) or fast (400kHz max) I2C masters to perform protocol conversion between the I2C master and any downstream 1-Wire slave devices. Relative to any attached 1-Wire slave device, the DS2484 is a 1-Wire master. Internal, user-adjustable timers relieve the system host processor from generating time-critical 1-Wire waveforms, supporting both standard and overdrive 1-Wire communication speeds.
