The VCS758 series current sensor IC by Vicorv offers an economical and accurate solution for AC and DC current sensing. It is a fully domestically developed open-loop Hall effect current sensor module, encompassing chip design and module assembly process.

The device features a precision, low-offset linear Hall circuit with a copper conductive path situated near the chip. The current flowing through this copper path creates a magnetic field, which the Hall IC converts into a proportional voltage. The close proximity of the magnetic signal to the Hall transducer optimizes the device’s accuracy. The low-offset, chopper-stabilized BiCMOS Hall IC provides precise proportional output voltage and is meticulously programmed at the factory.
