DS2483R+T Description

Short technical summary and product information.

The DS2483R+T is a versatile single-channel I2C to 1-Wire master bridge device designed by Analog Devices / Maxim Integrated. It interfaces directly with standard or fast I2C masters to perform protocol conversion for downstream 1-Wire slave devices. This controller supports both standard and overdrive 1-Wire communication speeds, with user-adjustable timers for critical waveforms like tRSTL, tMSP, tW0L, and tREC0.

 

The device offers dual-voltage operation, allowing independent voltage levels for the I2C and 1-Wire interfaces. It supports I2C operating voltages of 1.8V, 3.3V, and 5.0V, with a 1-Wire operating voltage range from 3.3V to 5.0V. The DS2483R+T includes strong pull-up features for 1-Wire power delivery to devices such as EEPROMs and sensors. It also supports a power-saving sleep mode and allows the 1-Wire port to be powered down under software control.

 

With a wide operating temperature range of -40°C to +85°C, the DS2483R+T is suitable for various applications including printers, medical instruments, industrial sensors, and cell phones. It features built-in ESD protection of ±8kV HBM on the IO pin. The component is supplied in a compact SOT-23-6 package, suitable for surface mounting.

 

Key electrical specifications include I2C communication speeds up to 400kHz, a supply voltage range of 1.71V to 5.25V, and a low supply current of 300µA. The controller function ensures efficient management of the 1-Wire protocol.
