Allegro Microsystems is offering Power Monitoring ICs like the ACS37800 in order to measure single phase AC and DC signals in many applications requiring reinforced isolation up to 517 V_RMS continuously, and 4.8 kV_RMS for dielectric Strength Test Voltage following the UL60950 standard. Coming in a compact SOIC16 package with only 0.85 mΩ internal conductor resistance, it can withstand high currents up to 90 A, and even 180 A with a lower accuracy without overheating, or consuming too much energy. It can communicate with the central system with SPI protocol when noise is important, and with the I²C interface when there are multiple sensors on one line. It also supports a wide array of applications thanks to the typical industrial temperature range of -40 to 125^oC, and two voltage supply options from 3 V to 5.5 V. Lastly, it features a 1 kHz bandwidth, and can react very quickly to overcurrent situations thanks to a fast user-programmable fault pin sending an alert in typically less than 5 microseconds.
