MAX22446EAWE+T

Digital Isolators Overview

The MAX22446EAWE+T is a reinforced, four-channel digital galvanic isolator from Analog Devices. It utilizes proprietary capacitive coupling technology to provide high-speed data transmission with low power consumption. The device operates within a supply voltage range of 1.71 V to 5.5 V and supports data rates up to 200 Mb/s. Key electrical parameters include an insulation voltage of 5000 Vrms, a typical common-mode transient immunity of 50 kV/µs, and a propagation delay of 12 ns. It functions reliably across an extended temperature range from -40°C to +125°C.

• Power electronics interfaces such as motor drives and inverters
• Communication gateways facilitating RS-485 or CAN bus isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing components. Confirm that the 'EAWE' designation corresponds to the SOIC-16 package variant. Ensure compatibility with the intended operating voltage range of 1.71 V to 5.5 V. Check for RoHS compliance status as indicated in official documentation. Validate that the manufacturer is Analog Devices Inc./Maxim Integrated to avoid counterfeit parts.

Digital Isolators Selection Notes

Select this component when reinforced isolation ratings are mandatory for safety standards. Consider the 200 Mb/s data rate for high-bandwidth applications. Evaluate the 5000 Vrms insulation voltage against system surge requirements. Assess the low power profile for battery-operated or thermally constrained designs. Compare the 12 ns propagation delay against timing constraints in the target circuit.

Digital Isolators Part Context

This part belongs to the MAX2244x family of digital isolators, which includes variants like the MAX22444 and MAX22446. These devices share similar core technologies but differ in channel counts and specific feature sets. The MAX22446 specifically offers four channels, making it suitable for parallel data buses or multi-signal isolation needs in compact form factors.
