GENERAL DESCRIPTION
The DS2482-800 is an I2C-to-1-Wire bridge device that interfaces directly to standard (100kHz max) or fast (400kHz max) I2C masters to perform bidirectional protocol conversion between the I2C master and any downstream 1-Wire slave devices. Relative to any attached 1-Wire slave device, the DS2482-800 is a 1-Wire master. Internal factorytrimmed timers relieve the system host processor from generating time-critical 1-Wire waveforms, supporting both standard and Overdrive 1-Wire communication speeds. To optimize 1-Wire waveform generation, the DS2482-800 performs slew-rate control on rising and falling 1-Wire edges and has a programmable feature to mask the fast presence pulse edge that some 1-Wire slave devices can generate. Programmable strong pullup features support 1-Wire power delivery to 1-Wire devices such as EEPROMs and sensors. The DS2482-800 combines these features with eight independent 1-Wire I/O channels. The I2C slave address assignment is controlled b...
