# [ACS71020](https://www.allegromicro.com/en/products/sense/current-sensor-ics/zero-to-fifty-amp-integrated-conductor-sensor-ics/acs71020)

The [Allegro ACS71020](https://www.allegromicro.com/en/products/sense/current-sensor-ics/zero-to-fifty-amp-integrated-conductor-sensor-ics/acs71020)

power monitoring IC greatly simplifies

the addition of power monitoring to many AC powered systems.

The sensor may be powered from the same supply as the

system’s MCU, eliminating the need for multiple power supplies

and expensive digital isolation ICs. The device’s 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.

## This Library

Is a comprehensive collection of register maps and their bitfields, 

for [EEPROM registers](/ACS71020/ACS71020_eeprom.h)

and [volatile registers](/ACS71020/ACS71020_volatile.h). 

When completed, developer would easily be able to get and set all

configurations, and read all measurements. The bitfields are indepedent

of protocol used, so both i2c and SPI will work. However, development

related to i2c will be prioritized.

## Note

Although most of the work has been done, this is an incomplete library

and is not intended to be used in its current form. Its concept has only 

been tested in software, never on an actual hardware platform.
