DS2484 Single-Channel 1-Wire Master

The DS2484 is an I2C-to-1-WireM 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 pr.

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.
