MT9522 Fully Integrated, Hall Effect-Based Linear Current Sensor IC with 4.8kV High-Isolation, 250KHz, SOP-16W Package 1 Product Description 2 Features The MagnTek® MT9522 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 MT9522 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. ￭ AEC-Q100 Qualified ￭ ±0.3% Typical Linearity Over Temperature ￭ Fast Output Response Time: 2.2 μs (typ.) ￭ 250kHz Signal Bandwidth ￭ 5.0V/3.3V Power Supply Operation ￭ Output Mode Option: A precise, proportional voltage is provided by the lowoffset, chopper-stabilized CMOS 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 1,2,3 and 4, to pins 5,6,7 and 8). The internal resistance of this conductive path is 0.75 mΩ typical, providing low-power loss. The terminals of the conductive path are electrically isolated from the signal leads (pins 9 through 16). This allows the MT9522 current sensor IC to be used in high-side current sense applications without use other costly isolation techniques. The MT9522 family provides SOP-16W package to customers, The package is RoHS compliant. ---Ratiometric Output Proportional to Power Supply ---Fixed Output Out of Proportion to Power Supply ￭ ￭ -40℃~150℃ Operating Temperature Primary Conductor Resistance ---0.75mΩ ￭ Sensing Current Range: (Bidirectional or Unidirectional) ---±20A, ±30A, ±40A, ±50A, ±65A, ±80A, ±100A ---+40A, +50A ￭ Output Voltage Proportional to AC or DC Current ￭ Extremely Stable Quiescent Output Voltage ￭ Device with Overcurrent FAULT Function and Flexible External FAULT Threshold Setting ￭ Non-Ratiometric Operation with Reference Output ￭ Near Zero Magnetic Hysteresis ￭ Safety Parameters: (UL62368 CU72227126 01) ---4.8kVrms 1min Dielectric Surge Isolation ---1097Vrms, 1550VDC or VPK Working Voltage ---7.5mm Clearance Distance ---8.2mm Creepage Distance ￭ Package Option: ---SOP-16W ￭ RoHS Compliant: (EU)2015/863 3 Applications ￭ Inverter current sensing ￭ Motor phase and rail current sensing ￭ PV String Inverters, MPPT current sensing ￭ On-Board Charger ￭ DC-DC ￭ Switching Power Supplies ￭ Overcurrent Protection ￭ UPS 4 Product Overview of MT9522 Not to scale magntek.com.cn | Magnetic Tech Makes Magic Change 1 Part No. Description MT9522WT SOP-16W Tape & Reel (1500 pcs/bag) Rev 2.0 PDF
