**Magn Tek** · Current Sensors · SOP-8

MT9223CT-30UR5 from Magn Tek, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IP+ | passive | Input current positive terminal (primary conductor). Pins 1 and 2 are shorted together externally. Part of the low-resistance (~1.2 mΩ) primary conduction path electrically isolated from the signal side. |
| 2 | IP+ | passive | Input current positive terminal (primary conductor). Pins 1 and 2 are shorted together externally to form the current input side of the primary path. |
| 3 | IP- | passive | Input current negative terminal (primary conductor). Pins 3 and 4 are shorted together externally to form the current output side of the primary path. Isolated from the signal-side pins by 2.4 kVRMS. |
| 4 | IP- | passive | Input current negative terminal (primary conductor). Pins 3 and 4 are shorted together externally. |
| 5 | GND | power_in | Signal ground reference for VCC, VOUT, and FILTER pins. |
| 6 | FILTER | passive | External filter capacitor pin used to set the output bandwidth. Cutoff frequency fc = 1/(2*pi*RF*CFILTER), with internal filter resistance RF(int) ~1.8 kΩ typ. Reducing bandwidth improves noise but increases response time. |
| 7 | VOUT | output | Analog output signal proportional to sensed primary current. For the -30UR5 (unidirectional) variant: VOQ = 0.5V at IP=0A, output swings 0.5V to 4.5V for 0..+30A with sensitivity 133.3 mV/A. Ratiometric to VCC. VOL max 0.3V, VOH min VCC-0.3V into RL >= 4.7 kΩ. |
| 8 | VCC | power_in | Positive supply voltage input. Nominal 5.0V (4.5V-5.5V range). ICC typ 14 mA, 20 mA max. A 0.1 µF CBYPASS capacitor between VCC and GND is required. |
