DS2484

Single-Channel 1-Wire Master

with Adjustable Timing and Sleep Mode

General Description

Benefits and Features

The DS2484 is an I C-to-1-Wire bridge device that

interfaces directly to standard (100kHz max) or fast

S I C Host Interface Supports 100kHz and 400kHz

I C Communication Speeds

(400kHz max) I C masters to perform protocol con-

version between the I C master and any downstream

S Standard and Overdrive 1-Wire Communication

Speeds

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, support-

ing 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

S 1-Wire Port Can Be Powered Down Under

Software Control

S Supports Power-Saving Sleep Mode (SLPZ Pin),

Where the 1-Wire Port is in High Impedance

allows different operating voltages on the I C and 1-Wire

S I C Operating Voltages: 1.8V ±±5, ꢀ.ꢀV ±105, and

side. Strong pullup features support 1-Wire power deliv-

ery 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.
