The DS2482-100 is an I²C to 1-Wire® bridge device
that interfaces directly to standard (100kHz max) or
fast (400kHz max) I²C masters to perform bi-
directional protocol conversion between the I²C
master and any downstream 1-Wire slave devices.
Relative to any attached 1-Wire slave device, the
DS2482-100 is a 1-Wire master. Internal factory
trimmed timers relieve the system host processor
from generating time-critical 1-Wire waveforms,
supporting both standard and Overdrive 1-Wire
communication speeds. To optimize 1-Wire
waveform generation, the DS2482-100 performs slew
rate control on rising and falling 1-Wire edges and
provides additional programmable features to match
drive characteristics to the 1-Wire slave environment.
Programmable strong pullup features support 1-Wire
power delivery to 1-Wire devices such as EEPROMs
and sensors. The DS2482-100 combines these
features with an output to control an external
MOSFET for enhanced strong pullup application. The
I²C slave address assignment is controlled by two
binary address inputs, resolving potential conflicts
with other I²C slave devices in the system.
