Maxim Unveils Monitoring Solution for Automation Systems
MaxSafe MAX22530, Linear Optocoupler
Monitoring measurements 50 times more accurate than adopted products


Automation system designers are continuously seeking ways to save board space, increase channel density, and improve the accuracy of voltage and current input monitoring, striving to enable system operators to monitor more precisely and reduce downtime.

On the 9th, Maxim Integrated expanded its 'MAXSafe' lineup by launching the 'MAX22530,' an isolated field self-powered 12-bit system monitoring solution. MAXSafe combines a micropower DC-DC converter with a communication line to power field circuits isolated from the control-side power supply, simplifying diagnostics for signal monitoring applications.

The 4-channel MAX22530 provides 50 times more accurate monitoring measurements compared to standard distributed linear optocoupler isolation solutions through isolated system monitoring.

Maxim's proprietary integrated solution technology, which combines a 12-bit ADC, DC-DC converter, configurable threshold detection, and chip-level diagnostic capabilities, has been applied. By integrating five ICs into a 12-bit ADC, not only is system design simplified, but the current transfer ratio (CTR) performance safety is increased by 50%, enabling the implementation of a highly stable sense resistance voltage.

In addition, by increasing measurement accuracy at four voltage and current inputs, it enables end users to make more rational decisions, thereby improving system performance and productivity. By integrating five components into a single IC, a size of 250 mm² was achieved, which is about 40% smaller than competitors' distributed solutions, and channel density was improved by 43%.
