DS2482S-100+ - Maxim Integrated Function Overview

The DS2482S-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 DS2482S-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 optimise 1 Wire waveform generation, the DS2482S-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 pull-up features support 1 Wire power delivery to 1 Wire devices such as EEPROMs and sensors. The DS2482S-100+ combines these features with an output to control an external MOSFET for enhanced strong pullup application.
