New devices complement existing family of high bandwidth current sensor ICs

Allegro MicroSystems Europe has added a new generation of high bandwidth current sensor ICs to their existing family of devices. The ACS732 and ACS733 current sensor ICs offer a fast, compact, and accurate solution for measuring high-frequency currents in DC-DC converters and other switching power applications. These devices are the first 1MHz offerings from the company to offer 3600 VRMS galvanic isolation ratings. The current sensor ICs are Hall-effect-based and include user-configurable overcurrent fault detection. These characteristics make them ideally suited for high-frequency transformer and current transformer replacement in applications operating at high voltages. The devices are suitable for all markets, including automotive, industrial, commercial, and communications systems. They may be used in motor control, load detection and management, switch-mode power supplies, and overcurrent fault protection applications. The devices are fully calibrated at the factory to provide a high accuracy solution over the entire operating temperature range.
