MAX22445FAWE+

MAX22445FAWE+ is a reinforced, fast, low-power, four-channel 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 5kVRMS 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. All channels on this device are always enabled, however, the default state of the outputs of this device is selectable. Applications include isolated SPI interface, fieldbus communications for industrial automation, isolated RS-485/RS-422, CAN, battery management, medical systems. Safety regulatory approvals include UL according to UL1577, cUL according to CSA bulletin 5A, VDE 0884-11 reinforced isolation.
