Product Overview
DS2484Q+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, this device 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, this device can be put in sleep mode where power consumption is minimal. It is used in applications such as printers, medical instruments, industrial sensors, 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
- Supply voltage range from 1.71V to 5.25V
- Supply current is 4µA maximum at (sleep mode, VCC = 5.25V)
- Power-on-reset trip point is 1V typical at (TA = -40°C to +85°C)
- Input leakage current (SLPZ PIN) is 6µA typical at (VCI2C
1.89V) - Operating temperature range from -40°C to +85°C, 8-lead TDFN-EP package
