Product Overview

DS2482X-101+T is an I²C-to-1-Wire® bridge device that interfaces directly to standard (100KHz max) or fast (400KHz max) I²C hosts to perform bidirectional protocol conversion between the I²C host and any downstream 1-wire server devices. Relative to any attached 1-wire server device, the DS2482-101 is a 1-wire host. Internal, factory-trimmed timers relieve the system host processor from generating time-critical 1-wire waveforms, supporting both standard and overdrive 1-wire communication speeds. To optimize 1-wire waveform generation, the DS2482-101 performs slew-rate control on rising and falling 1-wire edges and provides additional programmable features to match drive characteristics to the 1-wire server environment. Programmable, strong pullup features support 1-wire power delivery to 1-wire devices such as EEPROMs and sensors. It is used in applications such as printers, medical instruments, industrial sensors, cell phones, PDAs.
  • Allows easy interface between a I²C microport and a 1-wire server
  • I²C host interface supports 100KHz and 400KHz, I²C communication speeds
  • 1-wire host IO with selectable active or passive, 1-wire pullup
  • Provides reset/presence, 8-bit, single-bit, and 3-bit 1-wire IO sequences
  • Standard and overdrive 1-wire communication speeds
  • Two address inputs for I²C address assignment, minimizes line noise reducing system EMI
  • Slew-controlled 1-wire edges, operating voltage range from 2.9V to 5.5V
  • Strong 1-wire pullup provided by an internal low impedance signal path
  • PCTLZ output to optionally control an external MOSFET for stronger pullup requirements
  • Operating temperature range from -40°C to +85°C, 9-pin WLP package
