Magn Tek · Current Sensors · SOP-8

MT9221CT-06BR5 from Magn Tek, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IP+ passive Input current positive pin of the primary conductor (1.5 mΩ typ), shorted externally with pin 2 and carrying current to pins 3 and 4, isolated to 2600 Vrms from signal pins.
2 IP+ passive Input current positive pin of the primary conductor (1.5 mΩ typ), shorted externally with pin 1 and carrying current to pins 3 and 4, isolated to 2600 Vrms from signal pins.
3 IP- passive Input current negative pin of the primary conductor, shorted externally with pin 4, where the sensed current exits.
4 IP- passive Input current negative pin of the primary conductor, shorted externally with pin 3, where the sensed current exits.
5 GND power_in Signal ground, with a bypass capacitor (0.1 uF typical) required between VCC and GND.
6 FILTER passive Filter pin to set bandwidth, where an external capacitor reduces bandwidth from the 150 kHz internal value to optimize noise performance.
7 VOUT output Analog output signal proportional to primary current and ratiometric to VCC, with output load of at least 4.7 kΩ and 1 to 10 nF capacitance.
8 VCC power_in Power supply pin, 4.5 V to 5.5 V operating (5 V typ), 6 V absolute maximum.
