MAX22345SAAP+

MAX22345SAAP+ is a reinforced, fast, low-power, four-channel 3.75KVRMS digital isolator. This device transfers digital signals between circuits with different power domains, using as little as 0.74mW per channel at 1Mbps (1.8V supply). It features reinforced isolation for a withstand voltage rating of 3.75KVRMS for 60 seconds. It offers all possible unidirectional channel configurations to accommodate any 4-channel design, including SPI, RS-485, and digital I/O applications. It also features independent 1.71V to 5.5V supplies on each side of the isolator also makes the devices suitable for use as level translators. It is approved by UL according to UL1577, cUL according to CSA bulletin 5A, VDE 0884-11 reinforced isolation. It is used in applications such as isolated SPI interface, fieldbus communications for industrial automation, isolated RS-485/RS-422, CAN, battery management, medical systems.
