When do you need to add an I2C isolator at design time?

Last Update Time: 2019-07-02 15:41:18

Isolation prevents DC and abnormal AC power between the two parts of the system, but still supports signal and power transfer between the two parts. Isolation usually prevents electrical components or personnel from being exposed to dangerous voltage and current surges; isolation for protecting personnel is called enhanced isolation. I2C has become a popular global standard in many systems; therefore, isolated I2C has spread to most high-pressure markets.

Common isolated I2C applications include:

The microcontroller (MCU) in the network and server power supplies communicates to the MCU.

 

The MCU to analog-to-digital converter communicates in the automotive battery management system and medical system.

 

The MCU in the Power over Ethernet system communicates with the powered device controller.

 

Communication between the MCU and the current/power monitoring system.
