Description:

The DS2482S-100+T&R is a single-channel I²C-to-1-Wire bridge device that simplifies communication between a host microcontroller and 1-Wire slave devices. It provides bidirectional protocol conversion, allowing standard I²C interfaces to control 1-Wire peripherals such as sensors, memory devices, and authentication chips.

Features:

• I²C Interface Compatibility: Supports standard (100kHz), fast (400kHz), and high-speed (3.4MHz) modes.
• 1-Wire Master Functionality: Handles timing, reset, and data transactions autonomously.
• Programmable Active Pullup: Adjusts 1-Wire line drive strength for optimal performance.
• Strong Pullup Mode: Enables power delivery to parasitic-powered 1-Wire devices.
• Automatic CRC Generation: Verifies data integrity for 1-Wire communications.
• Low Power Consumption: Suitable for battery-powered applications.
• Industrial Temperature Range: Operates reliably in harsh environments.

This device is commonly used in industrial, automotive, and consumer applications where 1-Wire communication is required.
