#I2c isolator code#

Connect it into your circuit to get electrical isolation, and the code of sensor module in control board does not need to be modified, which is simple and convenient.ġ. This product is designed specifically for DFRobot I2C connector sensor or modules, plug and play, no welding. What's more, the on-board 5V isolation power chip can directly supply the sensor module, without additional power. In order to ensure stable operation of the sensor modules, it is necessary to isolate the signal and the power.Īfter the analog signal isolator, we launched this digital signal isolator which specifically isolates the I2C digital signal. Some sensors, such as pH sensors and electrical conductivity sensors, which share the same power source and measure in the same container, will interfere with each other and do not work properly. In this case, electrical isolation is needed to ensure the stable operation of the sensors. For example, a running pump in a fish tank will release signals into the water, which interferes the sensors in the fish tank. In many cases, interference sources are existing.

This digital signal isolator can be used for multi-parameter water quality detection systems to prevent water quality sensors from interfering with each other. “This integrated digital isolator simultaneously solves the design challenges of increasing communication bandwidth over the isolation barrier while also reducing PCB area in 48 and 96 port Ethernet switches.Gravity: Digital Signal Isolator is capable of isolating I2C digital signal and providing isolated power to the sensor module, effectively preventing mutual interference between the sensor modules. “The 3.4 MHz AS1705 isolator offers the highest speed solution for real-time network power diagnostics for PSE equipment,” said Elie Antoun, President & CEO of Akros Silicon. In both of these cases, the AS1705 reduces the PCB footprint of the isolation circuitry by 50%, simplifying board layout and reducing design time.

The integrated functionality of the AS1705 enables it to replace: either one I2C digital isolator and five optocouplers or one I2C digital isolator and a five-channel unidirectional digital isolator. The five unidirectional channels replace optocouplers or standalone unidirectional digital isolators and provide all of the isolated communication signals used by a PSE system, including system reset, PSE interrupt and three power good indicators from the system’s power supply units. This enables the system to allocate the precise amount of power required by each port while eliminating unnecessary power allocation, which in turn reduces system energy consumption. On the bidirectional I 2C channels, the AS1705’s 3.4 MHz data rate provides the needed bandwidth for a system’s processor to dynamically monitor and control the power requirements for multiple PSE controllers within a system. Built on Akros’ proven GreenEdgeTM digital isolation technology, each of the isolation channels are rated to provide 2.5 kV of galvanic isolation. The AS1705 comprises a dual channel bidirectional I 2C digital isolator as well as five unidirectional channels of isolation. Optimized to enable real-time telemetry and control of Power Sourcing Equipment (PSE) controllers used in Power-over-Ethernet capable (PoE) switches and routers, the AS1705’s 3.4 MHz communication speed and integration level are unmatched in the industry. Akros Silicon, a premier supplier of leading-edge intelligent energy management ICs, announced the AS1705 digital isolator.
