Separated system monitor replaces 5 components

Maxim Integrated’s MAX22530 Separation System Monitor reduces solution size by 40% and tightens accuracy by 50x.

Maxim Integrated Products, Inc. MAXSafe Integrated isolated micropower architecture line MAX22530, Insulated, field side, self-powered, 4-channel, 12-bit system monitor. The MAX22530 isolated system monitor claims to improve accuracy by a factor of 50 to increase system uptime in automated substation applications.

The new device allows automation system designers to improve the monitoring accuracy of voltage and current inputs with greater accuracy. The MAX22530 is said to improve monitoring measurement accuracy by a factor of 50 (+/- 50 percent to +/- 1 percent) compared to standard linear optocoupler isolation solutions made from discretes. Maxim’s unique integrated isolation technology, which combines a 12-bit ADC, DC-DC converter, user-configurable threshold detection levels, and chip-level diagnostics, enhances current transfer ratio performance stability and is ultra-stable. Achieve sex. Stable sense resistance voltage.

The MAX22530 offers better measurement accuracy across all four voltage and current inputs, allowing end users to make better real-time decisions, improve system performance, and increase productivity. ..

In addition, system monitoring solutions are said to reduce the size of the solution by 40% by integrating five components, including an isolated DC / DC converter and a 12-bit ADC. The 12-bit ADC solution also includes an integrated 1.8 V reference, a programmable threshold comparator for each channel, and isolation of both data and DC / DC power supplies.This integration will be converted to 250mm2 Solution size compared to 420 mm2 According to Maxim, the size of the closest competitive discrete solution.
