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

TMCS1101A1UQDR 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 current input terminal; withstands ±600VPK isolation voltage and conducts up to 30A RMS at 25°C through 1.8mΩ internal conductor. |
| 2 | IN+ | input | Positive current input terminal; withstands ±600VPK isolation voltage and conducts up to 30A RMS at 25°C through 1.8mΩ internal conductor. |
| 3 | IN- | input | Negative current input terminal; withstands ±600VPK isolation voltage and conducts up to 30A RMS at 25°C through 1.8mΩ internal conductor. |
| 4 | IN- | input | Negative current input terminal; withstands ±600VPK isolation voltage and conducts up to 30A RMS at 25°C through 1.8mΩ internal conductor. |
| 5 | GND | power_in | Ground reference for low-voltage signal chain and output, isolated from high-voltage input by ±600VPK barrier. |
| 6 | NC | unconnected | No connection; may be left floating or connected to GND or VS through capacitive or resistive connection within voltage range GND-0.3V to VS+0.3V. |
| 7 | VOUT | output | Analog output voltage with 50mV/A sensitivity, 0.1×VS zero-current reference, and output swing range approximately 5mV to VS-20mV at 10kΩ load. |
| 8 | VS | power_in | Positive power supply voltage for signal chain with operating range 3V to 5.5V and quiescent current 4.5-6mA. |
