DS2484R+U

The DS2484R+U is a single channel 1-wire master with adjustable timing and sleep mode in 6 pin SOT-23 package. It 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 I2C master and any downstream 1-wire slave devices. Relative to any attached 1-wire slave device, the IC is a 1-wire master. Internal, user-adjustable timers relieve system host processor from generating time-critical 1-wire waveforms, supporting both standard and overdrive 1-wire communication speeds. 1-wire bus can be powered down under software control. The dual-voltage operation allows different operating voltages on I2C and 1-wire side. Strong pull-up features support 1-Wire power delivery to 1-Wire devices such as EEPROMs and sensors. When not in use, IC can be put in sleep mode where power consumption is minimal.
