DS2484R+T (MAXIM INTEGRATED PRODUCTS)
Интерфейсные мосты, I2C в 1-проводной, 1.71 В, 5.25 В, SOT-23, 6 вывод(-ов), -40 °C
The DS2484R+T is a single channel 1-wire master with adjustable timing and sleep mode in 6 pin SOT-23 package. It 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 I2C master and any downstream 1-wire slave devices. Relative to any attached 1-wire slave device, the IC is a 1-wire master. Internal, user-adjustable timers relieve system host processor from generating time-critical 1-wire waveforms, supporting both standard and overdrive 1-wire communication speeds. 1-wire bus can be powered down under software control. The dual-voltage operation allows different operating voltages on I2C and 1-wire side. Strong pull-up features support 1-Wire power delivery to 1-Wire devices such as EEPROMs and sensors. When not in use, IC can be put in sleep mode where power consumption is minimal.
- Supply voltage range is 1.71V to 5.25V
- Operating temperature range from -40°C to 85°C, independent of I2C voltage
- Adjustable 1-wire Ttiming 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 1.8V -5% to 5.0V +5%
- Built-in ESD protection level of ±8KV human body model (HBM) contact discharge on IO pin
- Maximum power-on reset trip point is 1.5V
- Maximum supply current is 300µA at no communication, VCC = full range
