ACS37800型: Highly Isolated, Programmable AC and DC Power Monitoring IC

Description

The ACS37800 power monitoring IC greatly simplifies the addition of power monitoring to any AC and DC powered device. By making use of Allegro’s Hall-effect-based, galvanically isolated integrated current sensor technology, reinforced isolation can be achieved without extra board space. The sensor can also be powered from the same supply as the MCU, eliminating the need for multiple power supplies and digital isolation ICs. Furthermore, 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, resulting in a highly integrated power monitoring solution reducing PCB footprint.

Two Hall plates are used for this measurement to deferentially sense the field, thus eliminating errors due to stray magnetic fields. Multiple parameters like averaging and zero crossing time or channels, and fault levels are user-programmable. The sensor features all key power measurements, which can be read out through I2C or SPI, as well as dedicated pins for voltage or current zero crossing (suitable for light-dimming applications) and fast overcurrent fault (for short-circuit detection). These two pins can also be configured to flag a VRMS under/overvoltage.

ACS37800采用小型、薄型、表面贴装SOIC16宽体封装。ACS37800是无铅的,在出厂前已完全校准。它可以很容易地配置由于GUI软件下载。在应用中进一步的客户校准可以提高精度。
