Allegro MicroSystems ACS712ELCTR-30A-T Environmental and export classification status description

The ACS712ELCTR-30A-T is a Hall-effect based current sensor capable of measuring AC and DC currents up to 30A. It offers an analog output proportional to the sensed current and features a low resistance, allowing it to operate with minimal impact on the circuit being monitored. With its integrated chip design, it simplifies the process of current monitoring in various applications. Functions 1. Current Sensing: Measures the amount of current flowing through a conductor. 2. Isolation: Provides electrical isolation between the high-current circuit and low-voltage control circuitry. 3. Analog Signal Output: Outputs a voltage signal that is linearly proportional to the sensed current. 4. Bidirectional Measurement: Capable of measuring both positive and negative current flows. Applications - Motor Control: Used in applications for monitoring the current to electric motors in robotics and automation. - Power Monitoring: Suitable for energy management systems to monitor power consumption. - Battery Management: Implemented in battery chargers and management systems to monitor charge/discharge currents. - Overcurrent Protection: Can be used in circuit protection applications to detect overcurrent conditions. - Renewable Energy: Monitors current in solar inverters and electric vehicle charging systems. Alternative Parts 1. ACS713: Similar Hall-effect current sensor family, offering different current ranges (up to 50A and 20A). 2. INA219: A digital power monitor with I2C communication, capable of measuring voltage and current simultaneously. 3. ACS758: Another Hall-effect current sensor but with a higher current rating (up to 200A). 4. LM319: A current shunt monitor that operates in a different manner than Hall-effect sensors. Embedded Modules - Current Sensor Evaluation Kits: Allegro offers evaluation kits for the ACS712, allowing for easy integration and testing within a microcontroller environment. - Development Boards: Some third-party boards integrate ACS712 with microcontrollers for rapid prototyping.
