Product Introduction
The Allegro ACS37800 power monitoring IC greatly simplifies the addition of power monitoring to many AC or DC powered systems. The sensor may be powered from the same supply as the system MCU, eliminating the need for multiple power supplies. The device construction includes a copper conduction path that generates a magnetic field proportional to applied current. The magnetic field is sensed differentially to reject errors introduced by common mode fields.
Allegro Hall- effect- based, galvanically isolated current sensing technology achieves reinforced isolation ratings in a small PCB footprint. These features enable isolated current sensing without expensive Rogowski coils, oversized current transformers, isolated operational amplifiers, or the power loss of shunt resistors.
The ACS37800 power monitoring IC offers key power measurement parameters that can easily be accessed through its SPI or I²C digital protocol interfaces. Dedicated and configurable I/O pins for voltage/current zero crossing, undervoltage and overvoltage reporting, and fast overcurrent fault detection are available in I²C mode. User configuration of the IC is available through on- chip EEPROM.
The ACS37800 is provided in the SOIC16 wide- body package, is lead (Pb) free, and is fully calibrated prior to shipment from the Allegro factory. Customer calibration can further increase accuracy in application.
