DS2482S-800+ 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 bi-directional 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 factory-trimmed 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 by three binary address inputs, resolving potential conflicts with other I²C slave devices in the system.
