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 bi-directional protocol conversion between the I²C master and any downstream 1-Wire slave devices.
The DS2482-800 is an I²C‑to‑1‑Wire bridge device that provides eight independent 1‑Wire master channels. It converts standard (100 kHz) or fast (400 kHz) I²C bus signals into bi‑directional 1‑Wire communication, handling timing and waveform generation internally.
Key features include selectable active or passive pull‑up, strong pull‑up for power delivery, slew‑rate controlled edges, and presence‑pulse masking. The device offers a 16‑pin SO package, operates from 2.9 V to 5.5 V, and supports temperatures from –40 °C to +85 °C. Registers for channel selection, configuration, status and data enable flexible control via the I²C host interface.
