DS2483 Overview

Single-Channel 1-Wire Master with Adjustable Timing and Sleep Mode

19-6164; Rev 0; 12/11
DS2483
Single-Channel 1-Wire Master
with Adjustable Timing and Sleep Mode
General Description
The DS2483 is an I
2
C-to-1-Wire
M
bridge device that
interfaces directly to standard (100kHz max) or fast
(400kHz max) I
2
C masters to perform protocol con-
version between the I
2
C master and any downstream
1-Wire slave devices. Relative to any attached 1-Wire
slave device, the DS2483 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
allows different operating voltages on the I
2
C and 1-Wire
side. Strong pullup features support 1-Wire power deliv-
ery to 1-Wire devices such as EEPROMs and sensors.
When not in use, the DS2483 can be put in sleep mode
where power consumption is minimal.
