DS28E17 1-Wire-to-I²C Master Bridge

Maxim’s DS28E17 is a 1-wire slave to I²C master bridge device

Image of Maxim DS28E17 1-Wire-to-I2C Master BridgeMaxim’s DS28E17 is a 1-wire slave to I2C master bridge device that interfaces directly to I2C slaves at standard (100 kHz maximum) or fast (400 kHz maximum). Data transfers serially by means of the 1-wire protocol, which requires only a single data lead and a ground return. Every DS28E17 is guaranteed to have a unique 64-bit ROM registration number that serves as a node address in the 1-wire network. Multiple DS28E17 devices can coexist with other devices in the 1-wire network and be accessed individually without affecting other devices. The DS28E17 allows using complex I2C devices such as display controllers, ADCs, DACs, I2C sensors, and more in a 1-wire environment. Each self-timed DS28E17 provides 1-wire access for a single I2C interface.
