具有集成导体的 0 至 50 A 电流传感器 IC

Really Cool. Really Efficient. New 400 kHz current sensors enable more sustainable designs in switch-mode power designs.

P0103 - As solar installations grow larger and more ambitious by the day, new trends in current sensing are emerging for this expanding energy market.

This application note describes multiple methods for measuring and characterizing system bandwidth, with a focus on the impulse response method. Allegro’s ACS720 is the perfect device to validate the test methods outlined here.

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 monitoring and control, and this is where current sensors are used.

AN296100: Allegro current sensor ICs allow design engineers to use Hall-effect based current sensor ICs in new applications where increased energy efficiency or new operating features are required. Wherever current sensing is needed, an integrated Hall-effect IC can provide a solution.
