DS2484R+T Description

Short technical summary and product information.

The DS2484R+T from Analog Devices is a versatile I2C-to-1-Wire bridge device designed to interface with standard or fast I2C masters. It performs protocol conversion between the I2C master and downstream 1-Wire slave devices, acting as a 1-Wire master itself. This device supports both standard (100kHz max) and fast (400kHz max) I2C communication speeds, as well as standard and overdrive 1-Wire communication speeds.

 

Key features include user-adjustable timers for critical 1-Wire waveforms, allowing for flexible timing configurations. The 1-Wire port can be powered down under software control, and the device supports a power-saving sleep mode via the SLPZ pin. Dual-voltage operation allows for different operating voltages on the I2C and 1-Wire sides, with a built-in level translator. Strong pullup features facilitate power delivery to 1-Wire devices like EEPROMs and sensors. The DS2484R+T offers built-in ESD protection of ±8kV HBM on the IO pin.

 

This controller operates within a temperature range of -40°C to +85°C. It is available in an 8-pin TDFN and a 6-pin SOT23 package. Applications include printers, medical instruments, industrial sensors, and cell phones.
