MAX22245BAWA+

MAX22245BAWA+ is a reinforced, fast, low-power, two-channel digital isolator. It features reinforced isolation for a withstand voltage rating of 5kVRMS for 60 seconds. This device transfers digital signals between circuits with different power domains, using as little as 0.78mW per-channel at 1Mbps (1.8V supply). The low-power feature reduces system dissipation, increases reliability, and enables compact designs. This device features low propagation delay and low clock jitter, which reduces system latency. 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 used in applications such as automotive, hybrid electric vehicle, chargers, battery management systems (BMS), inverters, industrial, isolated SPI, isolated RS-232, RS-485/RS-422, CAN, fieldbus communications.
