MAX12931FASA+

MAX12931FASA+ is a 2-channel, 3kV/5KVRMS digital galvanic isolator. This device transfers digital signals between circuits with different power domains while using as little as 0.65mW per channel at 2Mbps with 1.8V. The two channels of the MAX12931 transfer data in opposite directions. Independent 1.71V to 5.5V supplies on each side of the isolator also make the devices suitable for use as level translators. It is approved by UL according to UL1577, cUL according to CSA bulletin 5A. It is used in applications such as fieldbus communications for industrial automation, isolated RS232, RS-485/RS-422, CAN, general isolation application, battery management, and medical systems.
