Magn Tek · Current Sensors · SOP-8
MT9223CT-25BR5 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 | Primary current input terminal, shorted to pin 2 in the typical application, forming the positive end of the 1.2 mΩ (typ) primary conductor path that is electrically isolated from pins 5 to 8. |
| 2 | IP+ | passive | Primary current input terminal, shorted to pin 1 in the typical application, forming the positive end of the 1.2 mΩ (typ) primary conductor path that is electrically isolated from pins 5 to 8. |
| 3 | IP- | passive | Primary current negative terminal, shorted to pin 4 in the typical application, forming the return end of the 1.2 mΩ (typ) primary conductor path that is electrically isolated from pins 5 to 8. |
| 4 | IP- | passive | Primary current negative terminal, shorted to pin 3 in the typical application, forming the return end of the 1.2 mΩ (typ) primary conductor path that is electrically isolated from pins 5 to 8. |
| 5 | GND | power_in | Signal ground for the sensor; a CBYPASS capacitor (0.1 µF in the typical application) between VCC and GND is stated to be necessary. |
| 6 | FILTER | passive | Filter pin used to reduce the device bandwidth from the internal 150 kHz to optimize noise, with the response time increasing proportionally; the datasheet gives an internal filter resistance RF(int) of 1.8 kΩ (typ). |
| 7 | VOUT | output | Analog output signal with ratiometric quiescent voltage (VCC/2 for the ±25 A bidirectional part); the output low saturation is 0.3 V max and high saturation is VCC-0.3 V min at RL ≥ 4.7 kΩ, and the output capacitance load CL must be 1 to 10 nF. |
| 8 | VCC | power_in | Power supply input with a 4.5 V to 5.5 V operating range (5 V typical) and a 6 V absolute maximum rating. |
