Allegro MicroSystems ACS37630 Linear Vertical Hall-Effect Sensor IC
Allegro MicroSystems ACS37630 Linear Vertical Hall-Effect Sensor IC is contactless and utilizes high-precision vertical Hall technology for applications where currents flow through a busbar or PCB. When used with a U-core concentrator, this sensor achieves high immunity to stray fields while simplifying the mechanical assembly relative to a traditional C-core current sensor. This sensor features factory-programmed temperature compensation (TC) that provides a low thermal drift sensitivity of ±0.7% and a fast response time of 1.6µs. Allegro MicroSystems ACS37630 Linear Vertical Hall-Effect Sensor IC is suitable for green energy, power supplies, power distribution units (PDUs), battery disconnect units (BDUs), and smart fuse applications.
