Allegro is claiming isolation up to 1.3kV dc (650V reinforced) for a series of current sensors that work up 400A (ac and dc) and respond in 2.5µs for fast over-current detection. Safety-critical applications such as vehicles and robotics are the target. ACS772 is a 200kHz bandwidth automotive grade current sensor for 50 to 400A, with 100μΩ ...
