Fully integrated, monolithic, power-monitoring IC with reinforced isolation

Products

Allegro MicroSystems has released a fully integrated, small form-factor, power-monitoring IC with reinforced voltage isolation.

Allegro’s ACS724 and ACS711 current sensor ICs are commonly used in Internet-connected power outlets and IoT devices. The ACS71020 improves upon these ICs by including power-sensing functions and by eliminating power and isolation components that would otherwise increase the cost and size of systems.

The ACS71020 uses Allegro’s innovative Hall-effect current sensor IC technology with line voltage sensing (to voltage levels > 500VRMS) and a dedicated metrology engine that calculates power levels. This enables the first power monitor IC that can be powered from the same voltage supply as the system microprocessor, without needing digital isolators or multiple power supplies.

The new IC simplifies common power measurements by offering digital computation of parameters including active, reactive and apparent power.
