EV chargers for electric cars must be safe and reliable. Compact current sensors from Allegro help minimize heat dissipation, and can be used in EV charging stations for both residential and commercial buildings. Level 1 and 2 EV chargers are the most common and affordable for households and businesses with EV charging stations installed in parking garages. Special commercial chargers, also called superchargers, are Level 3 Fast DC chargers that deliver >50kW power to high-end electric cars and EVs.
Drawing up to 80A of current, Level 1 and 2 EV chargers plug into 120 VAC/230 VAC wall outlets and can take advantage of our safe, reliable, and power-efficient solutions. Level 3 Fast DC chargers have hundreds of amps of current flowing through them, and high-voltage isolation is required to ensure user safety. Allegro core-based and coreless current sensors are perfect for cases where the lowest heat generation and the highest current sensing accuracy are needed.

Modern cars have become increasingly power hungry. Even the “least electrified” vehicles include advanced electronics for infotainment, safety, and engine control. Fully electric vehicles further add high-voltage power domains to charge and drive. Each of these systems shares the need for power ...Learn More
This application note will describe the use of the new high current ACS772 Hall-effect current sensor integrated circuit (IC) from Allegro MicroSystems and will give an overview of its features and improvements from previous Allegro high-current sensors.Learn More
AN296154 - This application note describes the use of the new highly isolated, high bandwidth ACS733 Hall-effect current sensor integrated circuit (IC) from Allegro MicroSystems and gives an overview of its features and advantages over a highspeed current transformer (CT) current sensing solution.Learn More
Allegro current sensor ICs use the Hall-effect to measure the magnetic field produced by an integrated, current-carrying loop, translating the magnetic field to a voltage which is proportional to the current flow.Learn More
