Allegro MicroSystems Releases a Fully Integrated, Monolithic Power Monitoring IC with Reinforced Isolation
Allegro’s new power monitor IC simplifies common power measurements by offering digital computation of parameters including active, reactive and apparent power. These power values can be read out through I²C or SPI. The IC also includes dedicated pins for voltage zero crossing (suitable for light-dimming applications) and fast overcurrent fault detection (for sensing short-circuits). The ACS71020 eliminates the need for opto-couplers, dual output isolated power supplies and a current sense-resistor in single phase power monitoring applications.
The ACS71020 is housed in a single SOIC-16 wide body package that provides a reinforced isolation rating up to 517 VRMS. This monolithic IC provides makes it simple to add power monitoring to any AC or DC powered device.
