GENERAL DESCRIPTION

FEATURES

ꢀ

Cꢀ I²C Host Interface, Supports 100kHz and 400kHz

I²C Communication Speeds

The DS2482-100 is an I²Cꢀ 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.

Cꢀ 1-Wire Master IO with Selectable Active or

Passive 1-Wire Pullup

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

Three-Bit 1-Wire IO Sequences

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 2 Address Inputs for I²C Address Assignment

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

+85°C

Cꢀ 8-Pin, 150-mil SO Package
