This document describes the features and characteristics of the ACS754xCB-100 current sensor, including high reliability, single +5V supply, 3 kVRMS isolation voltage, 35 kHz bandwidth, etc. The sensor is suitable for automotive systems, industrial systems, motor control, servo systems, power conversion, and battery monitoring applications.
The ACS754xCB-100 is a Hall‑effect based current sensor from Allegro MicroSystems that offers low‑offset, chopper‑stabilized operation with a single +5 V supply. It features 3 kV isolation between the primary current terminals and the sensor pins, a 35 kHz bandwidth, and an internal copper conductor with 100 µΩ resistance for low power loss. Typical applications include motor control, power conversion, automotive and industrial systems.
The document includes detailed electrical characteristics such as supply voltage, current, isolation voltage, sensitivity, and performance metrics like propagation delay, response time, and temperature‑dependent error. Physical specifications, package dimensions, and compliance with UL and IEC standards are also provided.
