The DS2483 is an I2C-to-1-WireM bridge device thatinterfaces directly to standard (100kHz max) or fast(400kHz max) I2C masters to perform protocol conversionbetween the I2C master and any downstream1-Wire slave devices. Relative to any attached 1-Wireslave device, the DS2483 is a 1-Wire master. Internal,user-adjustable timers relieve the system host processorfrom generating time-critical 1-Wire waveforms, supportingboth standard and overdrive 1-Wire communicationspeeds. In addition, the 1-Wire bus can be powereddown under software control. The dual-voltage operationallows different operating voltages on the I2C and 1-Wireside. Strong pullup features support 1-Wire power deliveryto 1-Wire devices such as EEPROMs and sensors.When not in use, the DS2483 can be put in sleep modewhere power consumption is minimal.
