Description

General part information

DS2484 Series

The DS2484 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 DS2484 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 DS2484 can be put in sleep mode where power consumption is minimal.ApplicationsCell PhonesIndustrial SensorsMedical InstrumentsPrinters
