The ACS37800 Power Monitoring IC, an advanced solution for real-time power measurement in AC and DC systems, was introduced by Allegro MicroSystems. Operating from the same voltage as the system microcontroller (MCU), the ACS37800 is designed for seamless integration and does away with the requirement for numerous power supplies.
The ACS37800, which comes inside an SOIC16 wide-body box and is certified under UL 62368-1 (edition 2) for reinforced isolation, is factory-calibrated with extra customer calibration options for even higher accuracy.
The ACS37800 is the best option for applications needing efficient, real-time power monitoring because of its 1 kHz bandwidth, included EEPROM for user programming, and compatibility with both floating and non-floating ground systems.
For precise and reinforced isolation, the device uses Hall-effect-based sensing instead of heavy Rogowski coils, current transformers, or shunt resistors.
To provide accurate energy monitoring, the IC offers measurements for active, reactive, and apparent power in addition to power factor.
The ACS37800 facilitates flexible system integration by providing simple data access via SPI or I2C interfaces.
A specialized fault pin ensures prompt reaction to electrical anomalies by detecting overcurrent circumstances in as little as 5 microseconds.
Control in AC applications is improved by dedicated pins that enable the detection of voltage and current zero-crossing.
The sensor is perfect for high-power applications because it can measure currents up to 90 A. Low Power Loss & High Inrush Capability: Little power loss and a robust inrush current endurance are guaranteed by a low-resistance copper conduction route.
