The first current sensor, ACS37630, is designed to be sat on top of a bus bar and partly surrounded by a U-core magnetic field concentrator.
“Its vertical Hall technology enables sensing parallel to the package surface, ideal for system integration with U-core magnets,” according to the company. “This contactless non-invasive current sensing solution eliminates the need for C-core magnets.”
Bandwidth is up to 250kHz) and 1.6µs is the typical output response time.
