DS2482-100 - Single-Channel 1-Wire Master

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.

Key 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.

DS2482-100 Single-Channel 1-Wire Master 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.
