MT9223 Fully Integrated, Hall Effect-Based Linear Current Sensor IC with 150kHz Bandwidth and 2.4 kVRMS Isolation 1 Product Description 2 Features The MagnTek® MT9223 product series is a fully integrated Hall Effect-based isolated linear current sensor device family designed for AC or DC current sensing in industrial, commercial, and communications systems. Each of the MT9223 consists of a precise, lowoffset, linear Hall circuit with a low-resistance current conductor path located near the surface of the die. Applied current flowing through this low-resistance current conductor path generates a magnetic field that the Hall IC converts into a proportional voltage. The current is sensed differentially in order to reject common-mode fields, improving accuracy in magnetically noisy environments. Device accuracy is optimized through the close proximity of the magnetic field to the Hall transducer. ￭ ±1.9% Typical Total Output Error ￭ ±0.5% Typical Linearity Over Temperature ￭ Fast Output Response Time: 4 μs (typ.) ￭ 150kHz Signal Bandwidth ￭ 5.0V Single Supply Operation ￭ -40℃~125℃ Operating Temperature A precise, proportional voltage is provided by the lowoffset, chopper-stabilized BCD Hall IC, which has been accurately calibrated when it is manufactured. The output of the device has a positive slope (>VOQ) when an increasing current flows through the primary current conduction path (from pins 1 and 2, to pins 3 and 4). The internal resistance of this conductive path is 1.2 mΩ typical, providing low-power loss. The terminals of the conductive path are electrically isolated from the signal leads (pins 5 through 8). This allows the MT9223 current sensor IC to be used in high-side current sense applications without use other costly isolation techniques. ￭ Output Voltage Proportional to AC or DC Current ￭

Circuit The typical application circuits of MT9223 series products include a bypass capacitor (CBYPASS capacitor between VCC and GND is necessary) and a filter capacitor as an additional external components. On the input side, pins 1 and 2 are shorted together, pins 3 and 4 are shorted together. The analog signal output is measured directly from the VOUT pin. The signal is proportional to the IP of the primary sensing current of AC or DC within the specified measurement range. The FILTER pin can be used to reduce bandwidth to optimize noise performance, but at the same time proportionally increase response time.
