ACS37800KMACTR-090B3-I2C
Overview
The ACS37800 is an integrated power monitoring IC designed to measure voltage, current, and power simultaneously from a single 3.3V supply. It combines Allegro's Hall-effect current sensing technology with a dedicated metrology engine to provide accurate digital outputs via an I2C interface, featuring reinforced isolation for high-voltage applications.
Why Choose This Part
The integrated Hall-effect sensor provides low-loss current sensing with high isolation without requiring a shunt resistor. Its onboard metrology engine simplifies firmware by calculating active, reactive, and apparent power directly on the chip, reducing the burden on the host microcontroller.

Key Specifications
Getting Started
Engineers should use the Allegro ACS37800 evaluation board (ASEK37800) for rapid prototyping and software development. Ensure the I2C bus pull-up resistors are sized for the 2.97V to 3.63V operating range, and refer to the metrology engine register map to configure the gain and offset for your specific load requirements.
