**Texas Instruments** · Current Sensors · SOIC-8

TMCS1101A2BQDR 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; the voltage on IN+ and IN- is limited to ±600 VPK relative to GND under the recommended operating conditions. |
| 2 | IN+ | input | Positive input current pin, internally common with pin 1; the voltage on IN+ and IN- is limited to ±600 VPK relative to GND under the recommended operating conditions. |
| 3 | IN- | input | Negative input current pin; the voltage on IN+ and IN- is limited to ±600 VPK relative to GND under the recommended operating conditions. |
| 4 | IN- | input | Negative input current pin, internally common with pin 3; the voltage on IN+ and IN- is limited to ±600 VPK relative to GND under the recommended operating conditions. |
| 5 | GND | power_in | Ground reference for the low-voltage side; the absolute maximum rating for VS is GND - 0.3 V to 6 V, and the input voltage limits are specified relative to this pin. |
| 6 | NC | unconnected | No internal connection; the pin can withstand capacitive or resistive connections to GND or VS, and shorting it to GND is recommended where acceptable. |
| 7 | VOUT | output | Analog output voltage proportional to the input current, with the output swing limited to VS - 0.1 V and GND + 10 mV at a 10 kΩ load and a maximum capacitive load of 1 nF. |
| 8 | VS | power_in | Analog supply pin; operate at 3 V to 5.5 V for the A1 to A3 variants and 4.5 V to 5.5 V for the A4 variants, with an absolute maximum of 6 V. |
