DS2482X-100+U

Controllers Overview

The DS2482X-100+U is a single-channel I²C-to-1-Wire bridge device manufactured by Analog Devices Inc./Maxim Integrated. It interfaces directly to standard (100kHz max) or fast (400kHz max) I²C masters to perform bidirectional protocol conversion between the I²C master and downstream 1-Wire slave devices. The device operates within a supply voltage range of 2.9V to 5.5V and supports an operating temperature range from -40°C to +85°C. It features internal factory-trimmed timers for time-critical 1-Wire waveform generation, supporting both standard and overdrive communication speeds. The component utilizes a 9-WLP package with dimensions of 1.53x1.53mm.

Controllers Procurement Notes

Verify current availability status as distribution channels may indicate limited stock or discontinuation. Confirm exact ordering suffixes match required packaging formats such as cut tape or reel. Ensure compatibility with existing system voltage levels and interface requirements before finalizing procurement decisions.

Controllers Selection Notes

Select this component when interfacing I²C microcontrollers with 1-Wire networks requiring protocol translation. Consider the 9-WLP package size for space-constrained designs. Verify that the two binary address inputs can resolve potential I²C address conflicts within the specific system topology.

Controllers Part Context

This part belongs to the DS2482 series of single-channel 1-Wire masters. It serves as a bridge allowing standard I²C hosts to communicate with various 1-Wire peripherals without complex software timing implementations. The device simplifies system design by handling time-critical 1-Wire waveforms internally.

Controllers Replacement Considerations

DS2482X-100+T is a verified substitute offering identical functionality in a different packaging format.
