Eight-Channel 1-Wire Master

GENERAL DESCRIPTION

FEATURES

ꢀ

Cꢀ I²C Host Interface, Supports 100kHz and 400kHz

I²C Communication Speeds

The DS2482-800 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

DS2482-800 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 DS2482-800 performs

slew-rate control on rising and falling 1-Wire edges

and has a programmable feature to mask the fast

presence pulse edge that some 1-Wire slave devices

can generate. Programmable strong pullup features

support 1-Wire power delivery to 1-Wire devices such

as EEPROMs and sensors. The DS2482-800

combines these features with eight independent 1-

Wire I/O channels. The I²C slave address assignment

is controlled by three binary address inputs, resolving

potential conflicts with other I²C slave devices in the

system.

Cꢀ 1-Wire Master I/O with Selectable Active or

Passive 1-Wire Pullup

Cꢀ Provides Reset/Presence, 8-Bit, Single-Bit, and

Three-Bit 1-Wire I/O Sequences

Cꢀ Eight Channels of Independently Operated

1-Wire I/O

Cꢀ Standard and Overdrive 1-Wire Communication

Speeds

Cꢀ Slew Controlled 1-Wire Edges

Cꢀ Selectable 1-Wire Slave Presence Pulse Falling

Edge Masking to Control Fast Edges on the

1-Wire Line

Cꢀ Supports Low-Impedance 1-Wire Strong Pullup

for EEPROMs, Temp Sensors, or Other 1-Wire

Slaves That Have Momentary High Current

Modes

Cꢀ Three Address Inputs for I²C Address

Assignment

Cꢀ Wide Operating Range: 2.9V to 5.5V, -40°C to

+85°C
