Hall Current Sensor 1. Product Introduction AH910W is a high-performance Hall-effect isolated wire current sensor chip for more effective measurement of AC or DC current, which can be widely used in industrial applications, mercial, and munication systems. AH910W series internal integration of a high precision, low noise linear Hall circuit and a low impedance main current loop wire, when the sampling current flows through the main current loop, the magnetic field generated in the Hall circuit induction of the corresponding electrical signal, through the signal processing circuit output voltage signal, so that the product output is strictly proportional to the measured current value. The linear Hall circuit is based on the low offset of BCD technology, and the chopper stable Hall chip can provide accurate proportional voltage, which is accurately calibrated during manufacturing. When the applied current flows through the internal current conduction path (from pins 123 and 4 to pins 5,6,7 and 8), the output of the chip has a positive slope (>VOQ). The typical internal resistance value of this conductive path is 0.75m Q, which can achieve low energy consumption. The terminals (pins [to 8) of the conductive path are Galvanic isolation from the signal lines (pins 9 to 16). This allows the AH910W current sensor IC to be used in high-end current detection applications without the need for other expensive isolation technologies. This series provides customers with S0P16W packaging that meets Ro HS requirements. 2.
