Single-Channel 1-Wire Master

DS482-10

General Description

Features

♦ I C Host Interface Supports 100kHz and 400kHz

The DS2482-100 is an I C-to-1-Wire bridge device

that interfaces directly to standard (100kHz max) or fast

I C Communication Speeds

(400kHz max) I C masters to perform bidirectional pro-

♦ 1-Wire Master IO with Selectable Active or

tocol conversion between the I C master and any

Passive 1-Wire Pullup

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

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

3-Bit 1-Wire IO Sequences

♦ Standard and Overdrive 1-Wire Communication

Speeds

♦ Slew-Controlled 1-Wire Edges

♦ Strong 1-Wire Pullup Provided by an Internal Low-

Impedance Signal Path

♦ PCTLZ Output to Optionally Control an External

MOSFET for Stronger Pullup Requirements

♦ Two Address Inputs for I C Address Assignment

enhanced strong pullup application. The I C slave

♦ Operating Range: 2.9V to 5.5V, -40°C to +85°C

♦ 8-Pin (150 mils) SO and 9-Bump WLP Packages

address assignment is controlled by two binary

address inputs, resolving potential conflicts with other

I C slave devices in the system.
