General Description
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 bidirectional pro-
tocol 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 over-
drive 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.
