Maxim Integrated DS2482X-100+T I²C to 1-Wire® Bridge Device

The DS2482X-100+T from Maxim Integrated is a sophisticated I²C to 1-Wire bridge chip that provides an efficient communication interface between a standard I²C bus and any 1-Wire slave device. This compact and reliable component is designed to serve a wide range of applications that require seamless integration between I²C-enabled microcontrollers and 1-Wire devices such as temperature sensors, serial number chips, or other specialty components that utilize the unique 1-Wire protocol.

Implementing the DS2482X-100+T in your design simplifies the 1-Wire setup by handling all the timing-critical and protocol-specific functions, thus freeing up valuable resources on the host microcontroller. The device supports a high-speed I²C interface with a maximum data rate of 400 kbps, allowing for rapid communication with the connected 1-Wire devices.

One of the standout features of the DS2482X-100+T is its built-in 1-Wire master with dedicated hardware to perform the 1-Wire bus protocol, which includes a programmable 1-Wire timing generator to accommodate various 1-Wire slave devices. This level of integration ensures a robust and reliable 1-Wire communication link, which is especially crucial in complex or noise-sensitive applications.

The device is available in a small SMT package, the 6-pin TSOC, which is suitable for space-constrained applications. Its operating temperature range of -40°C to +85°C makes it ideal for industrial and commercial environments where temperature extremes may be encountered.

Maxim Integrated's DS2482X-100+T also features a strong 1-Wire pullup to support power delivery to 1-Wire devices with higher current demands. Additionally, it has an adjustable 1-Wire slew rate control to optimize signal integrity and communication speed, depending on the specific requirements of the application.

Overall, the DS2482X-100+T is an indispensable component for designers looking to bridge the gap between I²C and 1-Wire protocols, providing a simple and efficient solution for multi-device networks where communication with 1-Wire devices is essential.
