DS2482S-100-C03+T

Controllers Overview

The DS2482S-100-C03+T is a single-channel I²C-to-1-Wire bridge manufactured by Analog Devices Inc./Maxim Integrated. It interfaces standard or fast I²C masters to downstream 1-Wire slave devices, performing bidirectional protocol conversion. 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 programmable strong pullup capabilities and slew-rate control for rising and falling edges to optimize waveform generation. The component utilizes an SOIC-8 package and draws a typical operating current of 750µA.

Controllers Feature Summary

• Provides bidirectional protocol conversion between I²C masters and 1-Wire slave devices
• Features internal factory-trimmed timers for standard and overdrive 1-Wire communication speeds
• Includes programmable strong pullup with an output to control external MOSFETs
• Supports selectable active or passive 1-Wire pullup modes

Controllers Applications

• Industrial sensors
• Medical instruments
• Printers

Controllers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required environmental standards and RoHS compliance before integration into final designs.

Controllers Selection Notes

Select this component when an I²C host requires direct interfacing with 1-Wire slaves without complex timing management. Consider the SOIC-8 package constraints and verify that the I²C address inputs (AD0, AD1) can resolve bus conflicts in the target system architecture.

Controllers Part Context

This part belongs to the DS2482 series of serial-to-1-Wire bridges. It serves as a master controller for 1-Wire networks, relieving the host processor from generating time-critical waveforms. The series supports various packages including WLP and SO types.
