The MCU1201 ADUM-1201 ADUM1201ARZ magnetic isolator replaces the photoelectric coupler

The ADUM1201 dual channel digital magnetic isolator replaces the optoelectronic couplerThe iCoupler digital isolator based on ADI patent USES the patented planar magnetic field isolation technology. The iCoupler technology is a patented isolation technology based on the chip size of the transformer rather than the combination of LED and photodiode used in the photocoupler. ICoupler technology eliminates the photoelectric conversion process in the photoelectric coupler, and adopts the patented iCoupler transformer technology to integrate the transformer driver and the receiving circuit, thus realizing the incomparable performance advantages of the photoelectric isolator. Because the iCouple transformer is manufactured directly on the chip using a chip level manufacturing process, the iCoupler channel is more efficient than the optoelectronic coupler in achieving inter-channel integration and other semiconductor functions more easily.Since there is no photoelectric conversion link affecting efficiency in the photoelectric coupler, the iCoupler digital isolator does not need to drive the external circuit of LED, and its power consumption is only 1/10 to 1/50 of that of the photoelectric coupler. This new electromagnetic isolation method is far superior to the optocoupler in the resistance to high temperature. The performance and reliability of the iCoupler digital isolator do not decline in the 125℃ high temperature environment. Therefore, low-cost and small-volume SOIC package can be adopted, which not only reduces the cost but also reduces the chip volume. In addition, the isolation channel of the iCoupler digital isolator has higher data transmission rate, timing accuracy and transient common mode rejection capability than that of the photoelectric coupler. Its rated isolation voltage is 2 times higher than that of the high isolation photoelectric coupler, and its data transmission rate and timing accuracy are 10 times higher. In addition, unlike the photoelectric coupler, the multi-channel iCoupler digital isolator can provide forward and reverse communication channels in the same chip, which makes the transmission direction of signals more flexible and simplifies the hardware connection between chips.Based on iCoupler technology, ADUM1201 has many advantages over the photoelectric isolator:Higher speeds up to 125Mbps.Lower power consumption 1/10 of the traditional photoelectric isolator when the power consumption is lower than the same data transmission rate, and the minimum working current is 0.8ma.The performance is higher than that of the traditional photoelectric isolator.Smaller size and higher integration, printed circuit board (PCB) area is 40% of the traditional photoelectric isolator.Different from the traditional photoelectric coupler, the multi-channel iCoupler digital isolator can provide forward and reverse communication channels in the same chip.The isolated ends of ADUM1201 have their own power supply and reference ground, and th
