TMCS1101A1BQDR 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 | Current-sense input; the measured current enters the internal 1.8 mΩ conductor through IN+ and IN- and the sensor treats current flowing into IN+ as positive, with input voltages limited to ±600 VPK relative to GND (pin 5). |
| 2 | IN+ | input | Second current-sense input pin on the same internal conductor as pin 1; it is printed as a separate IN+ pin in the pin table and carries the same ±600 VPK input voltage limit relative to GND. |
| 3 | IN- | input | Current-sense return input on the same internal conductor as pin 4; the input voltage is limited to ±600 VPK relative to GND (pin 5) and the continuous RMS current rating is 30 A at 25°C, derated with temperature. |
| 4 | IN- | input | Second current-sense return input pin on the same internal conductor as pin 3; it carries the same ±600 VPK input voltage limit relative to GND and the same derated continuous RMS current rating. |
| 5 | GND | power_in | Ground reference for the low-voltage side; the input voltage ratings VIN+ and VIN- are specified relative to this pin, and the output swing to ground is limited to about 5-10 mV at a 10 kΩ load. |
| 6 | NC | unconnected | No internal connection; the pin tolerates capacitive or resistive connections to GND or VS, the datasheet recommends shorting it to GND where acceptable, and its absolute maximum voltage range is GND - 0.3 V to VS + 0.3 V. |
| 7 | VOUT | output | Analog output voltage proportional to input current with zero-current level of 0.5 × VS for the B variants and 0.1 × VS for the U variants; it swings to within about 0.02-0.1 V of VS and 5-10 mV of GND at a 10 kΩ load and is stable up to 1 nF capacitive load. |
| 8 | VS | power_in | Low-voltage analog supply, with recommended operating range 3 V to 5.5 V for the A1-A3 variants and 4.5 V to 5.5 V for the A4 variants, absolute maximum 6 V, and a 0.1 µF low-ESR decoupling capacitor placed close to the VS and GND pins. |
