MAX22421CASA+

MAX22421CASA+ is a reinforced, ultra-low-power, two-channel digital isolator. This device transfers digital signals between circuits with different power domains, using as little as 90.7μW per channel at 1Mbps (1.8V supply). The ultra-low power feature reduces system dissipation, increases reliability, and enables compact designs. It features independent 1.71V to 5.5V supplies on each side also make the device suitable for use as level translators. The ultra-low power feature reduces system dissipation, increases reliability, and enables compact designs. It is approved by UL according to UL1577, cUL according to CSA bulletin 5A. It is used in applications such as 4-20mA loop process control, battery management, compact micro PLC, parasitically powered applications.
