Shaun Milano, Strategic Marketing Manager at Allegro MicroSystems describes the ACS712 low noise Hall Effect current sensor IC with 2100 VRMS voltage isolation, and shows how current sensors work and ...

This technical document presents some simple techniques in order to increase the measurable current range in current divider configurations using Allegro current sensor integrated circuits (ICs).

Isolation in this case, is from the mains, and it transpires that finding something that will do the job safely is tricky. Three isolated Hall-based current sensing modules are easy to obtain, as far ...

Allegro MicroSystems' two high-performance, low-noise 2100-Vrms isolation current sensors, the ACS712 and ACS713, provide lower noise and higher accuracy than previous generation current sensors.
