Magn Tek · Current Sensors · SOP-8
MT9523CT-50BF5 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 terminal, part of the internal conductor path (pins 1 and 2 to pins 3 and 4) with a typical resistance of 1.0 mΩ, electrically isolated from the signal pins 5 and 6. |
| 2 | IP+ | passive | Input current positive terminal, bonded to pin 1 as part of the internal 1.0 mΩ conductor path that is electrically isolated from the signal pins 5 and 6. |
| 3 | IP- | passive | Input current negative terminal, the return end of the internal 1.0 mΩ conductor path, electrically isolated from the signal pins 5 and 6. |
| 4 | IP- | passive | Input current negative terminal, bonded to pin 3 as part of the internal 1.0 mΩ conductor path, electrically isolated from the signal pins 5 and 6. |
| 5 | GND | power_in | Signal ground reference for the sensor outputs; the datasheet recommends placing the 0.1 µF bypass capacitor between the supply and ground pins close to the device. |
| 6 | VZCR | output | Zero-current reference voltage output (2.5 V fixed for the BF5 version, or ratiometric for BR versions), with a recommended 0.47 nF load capacitor, 4.7 kΩ minimum load resistance, and 1 nF maximum capacitive load to GND. |
| 7 | VOUT | output | Analog voltage output proportional to the input current, rated for 40 mA continuous source and sink current, not to exceed VCC + 0.5 V, with a load capacitance of 0.47 nF typical and 1 nF maximum to GND. |
| 8 | VCC | power_in | Supply voltage pin; the absolute maximum rating is 6 V, and the recommended supply for the 5 V version (BF5) is 4.5 V to 5.5 V. |
