MT9223CT-50BR5 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 pin. Terminal of the internal 1.2 mΩ (typ) primary current conductor. Pins 1 and 2 must be shorted together on the PCB to carry the sensed current into the device. |
| 2 | IP+ | passive | Input current positive pin. Second terminal of the primary conductor input; shorted with pin 1 to carry sensed current. |
| 3 | IP- | passive | Input current negative pin. Terminal of the internal primary conductor. Pins 3 and 4 must be shorted together to complete the primary current path. |
| 4 | IP- | passive | Input current negative pin. Second terminal of the primary conductor; shorted with pin 3 to complete the primary current path. |
| 5 | GND | power_in | Signal ground reference for the device output stage. |
| 6 | FILTER | passive | Filter pin to set signal bandwidth. Connect an external capacitor CFILTER to GND to lower the -3 dB corner frequency (fc = 1/(2π·RF·CFILTER), RF(int) ≈ 1.8 kΩ). Reducing bandwidth reduces noise but proportionally increases response time. |
| 7 | VOUT | output | Analog output signal proportional to the sensed primary current. Ratiometric to VCC: quiescent output = VCC×0.5 at IP=0 A; sensitivity is 40 mV/A on the -50BR5 (±50 A range), swinging 2.5 V±2 V over full scale. Drives loads ≥4.7 kΩ; VOL≤0.3 V, VOH≥VCC-0.3 V. |
| 8 | VCC | power_in | Power supply, 5 V nominal (4.5-5.5 V range). Typical ICC = 14 mA (max 20 mA). Requires a 0.1 µF bypass capacitor to GND close to the pin. |
