Digital isolators are components which transfer data across two independent circuitry domains by using a galvanic isolation method. This ensures any displacement current between the two domains does not flow. This technology can be used to block high voltages or large currents, and transmits digital information between these two circuits. 

The SI8712BC-B-IPR is a digital isolator from Silicon Labs and is specifically designed for use in industrial IEEE 802.3 compliant Power over Ethernet (PoE) control systems. Its bus powered design eliminates the need for auxiliary power sources, making it ideal for use in systems where the available memory is limited. With up to 5Mbps data rate performance and 2.5kV (basic insulation) of isolation rating, the SI8712BC-B-IPR makes communication between different domains safe and reliable.  

The SI8712BC-B-IPR is a single-channel device which features differential data line technology. It uses two separate data lines, commonly referred to as Data+ and Data-, that carry the same digital waveforms but are 180 degrees out of phase. Differential signaling improves noise immunity and enables the device to reliably transmit a digital signal for up to 5Mbps over long cables.  

The SI8712BC-B-IPR also features integrated protection diodes on the Data+ and Data- lines. This prevents the Data+ and Data- from reversing polarity in the event of an excessive voltage. In addition, the integrated protection diodes draw very low current and will not interfere with signal quality. 

The SI8712BC-B-IPR offers unparalleled reliability and performance in its waveform transmission. The device’s isolation feature effectively prevents any external disturbance to the data transmission and reduces the risk of power surges and system glitches. In addition, the device’s 2.5kV basic isolation rating makes it perfect for applications in harsh industrial environments. 

The SI8712BC-B-IPR is ideal for applications where it is critical to safely transfer data across two independent domains. Its design offers reliable transmission performance and its high isolation rating ensures maximum data protection. With its bus powered design, the SI8712BC-B-IPR is the perfect choice for use in limited memory systems and harsh industrial environments.
