MT9223CT-30BR5

Magn Tek · Current Sensors · SOP-8

MT9223CT-30BR5 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; primary current flows from pins 1 and 2 to pins 3 and 4, with 1.2 mΩ typical internal conductor resistance and the output rising for increasing current.
2 IP+ passive Input current positive pin, shorted to pin 1 in the typical application circuit, carrying the primary current into the sensor's low-resistance conductor path.
3 IP- passive Input current negative pin; primary current exits the conductor path here, and pins 3 and 4 are shorted together in the typical application circuit.
4 IP- passive Input current negative pin, shorted to pin 3 in the typical application circuit, forming the return end of the primary conductor path.
5 GND power_in Signal ground and reference for the analog output; a 0.1 µF bypass capacitor between VCC and GND is necessary.
6 FILTER passive Filter pin that sets device bandwidth with an external CFILTER using fc = 1/(2·π·RF·CFILTER), where internal RF is 1.8 kΩ typical; lower bandwidth reduces noise but increases response time.
7 VOUT output Analog output signal, specified at VOL max 0.3 V and VOH min VCC−0.3 V for RL ≥ 4.7 kΩ, with a capacitive load of 1 to 10 nF to GND.
8 VCC power_in Power supply input, 4.5 V to 5.5 V with 5 V typical and 6 V absolute maximum; the output is ratiometric to this supply.
