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.?
