Texas Instruments · Current Sensors · SOIC-8
TMCS1107A4BQDRQ1 from Texas Instruments, in a SOIC-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 | IN+ | input | Positive input current pin of the isolated primary conductor (tied internally to pin 2); current flowing into IN+ is treated as positive, and the IN+ to IN- voltage relative to GND is rated at -420 V to 420 VPK. |
| 2 | IN+ | input | Second positive input current pin, internally connected to pin 1, carrying the input current through the 1.8 mΩ lead-frame conductor; the input voltage relative to GND is rated at -420 V to 420 VPK. |
| 3 | IN- | input | Negative input current pin of the isolated primary conductor (tied internally to pin 4); the return path for the measured current, with the input voltage relative to GND rated at -420 V to 420 VPK. |
| 4 | IN- | input | Second negative input current pin, internally connected to pin 3; it should be paired with IN+ using merged copper input leads as recommended in the layout guidance. |
| 5 | GND | power_in | Ground reference for the low-voltage (sensor and output) side of the device; all input voltage ratings and the VOUT swing are referenced to this pin. |
| 6 | NC | unconnected | No internal connection; the pin can tolerate capacitive or resistive connection to GND or VS (shorting to GND is recommended where acceptable), and its absolute maximum voltage range is GND - 0.3 V to VS + 0.3 V. |
| 7 | VOUT | output | Analog voltage output proportional to the input current; the output swing is limited to about 0.1 V to 0.02 V from the supply rail and 5 mV to 10 mV above GND into a 10 kΩ load, and it can drive at most 1 nF capacitive load without sustained oscillation. |
| 8 | VS | power_in | Low-voltage analog supply pin; for the TMCS1107A4B-Q1 the operating supply range is 4.5 V to 5.5 V (absolute maximum GND - 0.3 V to 6 V), with a 0.1 µF low-ESR decoupling capacitor recommended close to the pin. |
