How does the acs71020 power monitoring IC work?
The ACS71020 power monitoring IC greatly simplifies the addition of power monitoring to any AC powered device. By making use of Allegro’s Hall-effect-based, galvanically isolated integrated current sensor technology, reinforced isolation can be achieved.
How are the two pins on the acs71020 used?
As the sensor is isolated, these pins can be easily accessed by the MCU without additional isolation to each signal. These two pins can also be configured to flag a VRMS under/overvoltage. The ACS71020 is provided in a small, low-profile, surface-mount SOIC16 wide-body package.

Which is power monitoring IC is pin to pin compatible?
Refer to the ACS37800 which is pin to pin compatible. The ACS71020 power monitoring IC greatly simplifies the addition of power monitoring to any AC powered device. By making use of Allegro’s Hall-effect-based, galvanically isolated integrated current sensor technology, reinforced isolation can be achieved.
Can you write volatile registers on an acs71020?
The ACS71020 supports factory and customer EEPROM space as well as volatile registers. The customer access code must be sent prior to writing these customer EEPROM spaces. In addition, the device includes a set of free space EEPROM registers that are accessible with or without writing the access code.
How does an isolated power monitoring IC work?
The sensor can be powered from the same supply as the MCU, eliminating the need for multiple power supplies and digital isolation ICs. The isolated current measurement is done by detecting the magnetic field from the integrated conductor, eliminating the need for external sense resistors, current transformers, or Rogowski coils.
