The MAX22445 5 kVRMS is a newly released four-channel reinforced digital isolator from Maxim Integrated Products, Inc. The MAX22445 delivers up to two times greater throughput at four times lower power consumption and provides reliable communication across the isolation barrier for the safe operation of compact industrial, medical and other equipment.
Overcoming the shortcomings of other digital isolators, the MAX22445 delivers reinforced, dual insulation barrier isolation for fast digital signals. The IC mitigates the dangers of high-voltage power and transfers signals of up to 200 Mbps with less power. It is available in a 16-pin wide-body SOIC package with 8 mm of creepage and clearance.
The digital isolator has low power with 0.41 mA per channel current consumption and 0.74 mW power consumption at 1 Mbps with VDDat 1.8 V. The IC has four times lower power consumption compared to competing solutions while also reducing heat generation and enabling reliable and compact designs.
It also has high speed with a maximum propagation delay of 10.5 ns and maximum data rate of 200 Mbps enable fast and accurate data acquisition and high-speed interfaces with wide timing margins. The IC delivers up to two times greater throughput versus other available solutions.
The MAX22445 has dual barriers that provide 5 kVRMS and 10 kV surge for reliable performance over a long product lifetime and meet the safety standards required for operator protection.
The MAX22445 is available at Maxim's website for $3.49 and the MAX22445FWEVKIT# evaluation kit is available for $32.
