GENERAL DESCRIPTION
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 bidirectional 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.

BENEFITS AND FEATURES
• Allows Easy Interface Between an I2C Micro Port and a 1-Wire Slave
    o I2C Host Interface Supports 100kHz and 400kHz I2C Communication Speeds
    o 8 Channels of Independently Operated 1-Wire I/O
    o 1-Wire Master I/O with Selectable Active or Passive 1-Wire Pullup
    o Provides Reset/Presence, 8-Bit, Single-Bit, and 3-Bit 1-Wire I/O Sequences
    o Standard and Overdrive 1-Wire Communication Speeds
    o Three Address Inputs for I2C Address Assignment
• Minimizes Line Noise, Reducing System EMI
    o Slew-Controlled 1-Wire Edges
• Supports EEPROMs, Temp Sensors, or Other 1-Wire Slaves That Have Momentary High Source Current Modes
    o Strong 1-Wire Pullup Provided by an Internal Low-Impedance Signal Path
    o PCTLZ Output to Optionally Control an External MOSFET for Stronger Pullup Requirements
• Wide Operating Range: 2.9V to 5.5V, -40°C to +85°C
• 16-Pin SO Package (150 mils)
