The DS2482-101 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 DS2482-101 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 DS2482-101 performs slew-rate control on rising and falling 1-Wire edges and provides additional programmable features to match drive characteristics to the 1-Wire slave environment. Programmable, strong pullup features support 1-Wire power delivery to 1-Wire devices such as EEPROMs and sensors. The DS2482-101 combines these features with an output to control an external MOSFET for enhanced strong pullup application. The I2C slave address assignment is controlled by one binary address input, resolving potential conflicts with other I2C slave devices in the system. When not in use, the device can be put in sleep mode where power consumption is minimal.
