Product Details

The DS2483 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 DS2483 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. In addition, the 1-Wire bus can be powered down under software control. The dual-voltage operation allows different operating voltages on the I²C and 1-Wire side. Strong pullup features support 1-Wire power delivery to 1-Wire devices such as EEPROMs and sensors. When not in use, the DS2483 can be put in sleep mode where power consumption is minimal.

Applications
