Product Overview

DS2484R+T is an I2C-to-1-Wire® bridge device that interfaces directly to standard (100KHz max) or fast (400KHz max) I2C hosts to perform protocol conversion between the I2C host and any downstream 1-wire server devices. Relative to any attached 1-wire server device, the DS2484 is a 1-wire host. 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 DS2484 can be put in sleep mode where power consumption is minimal. Applications include printers, medical instruments, industrial sensors, and cell phones.
  • 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
  • Built-in ESD protection level of ±8kV human body model (HBM) contact discharge on IO pin
  • 1.71 to 5.25V supply voltage
  • Supply current is 4µA maximum at sleep mode, VCC=5.25V
  • SCL clock frequency is 400KHz at TA=-40°C to +85°C
  • 6 SOT23 package
  • Operating temperature range from -40°C to +85°C
