Digital Isolator Boosts Throughput, Cuts Power

(Maxim Integrated Products)

Protecting industrial systems from high-voltage signals, Maxim Integrated Products’ MAX22445 5-kVRMS four-channel reinforced digital isolator is said to deliver up to 2x greater throughput at 4x lower power consumption over comparable devices. The MAX22445 provides reliable communication across the isolation barrier to ensure safe operation of compact industrial, medical and other equipment.


Features include:

  • Low Power: 0.41mA per channel current consumption and 0.74mW power consumption at 1Mbps with VDD at 1.8V. The IC has 4x lower power consumption compared to competing solutions while also reducing heat generation and enabling reliable and compact designs.
  • High Speed: Maximum propagation delay of 10.5ns and maximum data rate of 200Mbps enable fast and accurate data acquisition and high-speed interfaces with wide timing margins. The IC delivers up to 2x greater throughput versus other available solutions.
  • Robust and Reliable: Dual barriers of isolation provide 5kVRMS and 10kV surge for reliable performance over a long product lifetime and meet the safety standards required for operator protection. 

The MAX22445 is available for $3.49 each/1,000 and the MAX22445FWEVKIT# evaluation kit is available for $32. For greater illumination, consume the MAX22444–MAX22446 datasheet.
