Overview

  • I²C Host Interface Supports 100kHz and 400kHz I²C Communication Speeds
  • Standard and Overdrive 1-Wire Communication Speeds
  • Adjustable 1-Wire Timing for tRSTL, tMSP, tW0L, and tREC0
  • 1-Wire Port Can Be Powered Down Under Software Control
  • Supports Power-Saving Sleep Mode (SLPZ Pin), Where the 1-Wire Port is in High Impedance
  • I²C Operating Voltages: 1.8V ±5%, 3.3V ±10%, and 5.0V +5/-10%
  • Built-In Level Translator: 1-Wire Operating Voltage from 3.3V -10% to 5.0V +5%, Independent of I²C Voltage
  • Built-In ESD Protection Level of ±8kV Human Body Model (HBM) Contact Discharge on IO Pin
  • -40°C to +85°C Operating Temperature Range
  • 8-Pin TDFN and 6-Pin SOT23 Packages

The DS2483 is an I²C-to-1-Wire® bridge device that interfaces directly to standard (100kHz max) or fast (400kHz max) I²C masters to perform protocol conversion between the I²C master and any downstream 1-Wire slave devices. Relative to any attached 1-Wire slave device, the DS2483 is a 1-Wire master. Internal, user-adjustable timers relieve the system host processor from generating time-critical 1-Wire waveforms, supporting both standard and overdrive 1-Wire communication speeds. In addition, the 1-Wire bus can be powered down under software control. The dual-voltage operation allows different operating voltages on the I²C and 1-Wire side. Strong pullup features support 1-Wire power delivery to 1-Wire devices such as EEPROMs and sensors. When not in use, the DS2483 can be put in sleep mode where power consumption is minimal.

Product Details

The DS2483 evaluation system (EV system) consists of a DS2483 evaluation kit (EV kit) and a DS9400 USB-to-I²C adapter. The DS2483 is an I²C-to-1-Wire® bridge device that performs protocol conversion from an I²C Master to any attached 1-Wire slave devices. Relative to any attached 1-Wire slave device, the DS2483 is a 1-Wire master. The evaluation software runs under a Windows® 7 or Windows XP® operating system (OS), providing a handy user interface to exercise the features of the DS2483.

Order the DS2483K# for the complete EV system to evaluate the DS2483 using a PC. Evaluation software for the EV system is also available on our website at: www.maximintegrated.com/evkit.
