This application provides a current-type Hall effect sensor circuit, belonging to the technical field of Hall effect sensor circuits. Addressing the problem of poor output signal stability in Hall effect sensor circuits, this application provides a current-type Hall effect sensor circuit, including: an operational amplifier, a voltage divider unit, a feedback unit, a first RC low-pass filter unit, and a second RC low-pass filter unit; the first RC low-pass filter unit is connected between the non-inverting input terminal of the operational amplifier and an external driving module, which outputs a Hall signal during driving; a voltage divider unit is connected between the inverting input terminal of the operational amplifier and the power supply voltage terminal, and a feedback unit is connected between the output terminal of the operational amplifier and its inverting input terminal, forming a feedback loop, with the power supply voltage terminal providing the power supply voltage signal; the second RC low-pass filter unit is connected between the output terminal of the operational amplifier and an external processing module. This application has strong adaptability and high output signal stability.
