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 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.
FEATURES
▪ I²C Host Interface, Supports 100kHz and 400kHz I²C Communication Speeds
▪ 1-Wire Master IO with Selectable Active or Passive 1-Wire Pullup
▪ Provides Reset/Presence, 8-Bit, Single-Bit, and Three-Bit 1-Wire IO Sequences
▪ Standard and Overdrive 1-Wire Communication Speeds
▪ Slew Controlled 1-Wire Edges
▪ Selectable 1-Wire Slave Presence-Pulse Falling Edge Masking to Control Fast Edges on the 1-Wire Line
▪ Supports Low-Impedance 1-Wire Strong Pullup for EEPROMs, Temp Sensors, or Other 1-Wire Slaves that have Momentary High Current Modes
▪ 2 Address Inputs for I²C Address Assignment
▪ Wide Operating Range: 2.9V to 5.5V, -40°C to +85°C
▪ 8-Pin, 150-mil SO Package
APPLICATIONS
▪ Printers
▪ Medical Instruments
▪ Industrial Sensors
▪ Cell Phones, PDAs
