Introduction

The GZC6201 product series is an open-loop current sensor based on the Hall effect principle, widely used for AC or DC current detection in industrial, commercial, and communication systems. Each GZC6201 consists of a high-precision, low-temperature-drift linear Hall IC, a magnetic core, and a built-in current conductor path with low insertion resistance. The applied current flowing through this low-resistance current conductor path generates a magnetic field, which the Hall IC converts into a voltage signal output proportional to the input current. The magnetic core integrated within the product effectively suppresses interference from external common-mode magnetic fields, improving accuracy in magnetically noisy environments.

The GZC6201 undergoes precise factory calibration of the output voltage to meet different current range requirements. When the applied current flows through the internal current conduction path (from pins 8, 9, and 10 to pins 5, 6, and 7), the output of the device exhibits a positive slope (>VOQ). The typical internal resistance of this conduction path is 0.21mΩ, enabling low power dissipation. The terminals of the conduction path (pins 5 to 10) are electrically isolated from the signal lines (pins 1 to 4). This allows the GZC6201 current sensor to be used in high-side current sensing applications without the need for other costly isolation techniques.

The product is designed and tested in accordance with industry standards including IEC61010 and IEC61326, and complies with CE, RoHS, and other requirements.
