TMCS1108A4UQDR 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 | Input current positive terminal of the isolated input conductor (1.8 mΩ), rated at ±120 V absolute maximum relative to GND pin 5 and ±100 V recommended. |
| 2 | IN+ | input | Second input current positive terminal, tied to the same isolated input conductor as pin 1, with the same ±120 V absolute maximum and ±100 V recommended limits relative to GND. |
| 3 | IN- | input | Input current negative terminal of the isolated input conductor, with the same ±120 V absolute maximum and ±100 V recommended limits relative to GND pin 5. |
| 4 | IN- | input | Second input current negative terminal, tied to the same isolated input conductor as pin 3, with the same ±120 V absolute maximum and ±100 V recommended limits relative to GND. |
| 5 | GND | power_in | Ground reference for the low-voltage side; the input voltages on IN+ and IN- are specified relative to this pin. |
| 6 | NC | unconnected | No internal connection; the pin tolerates capacitive or resistive connections to GND or VS and should be shorted to GND where acceptable, with an absolute range of GND - 0.3 V to VS + 0.3 V. |
| 7 | VOUT | output | Analog output voltage proportional to the input current, with a zero-current level of 0.1 × VS for the TMCS1108A4U, an absolute range of GND - 0.3 V to VS + 0.3 V, and a maximum capacitive load of 1 nF without sustained oscillation. |
| 8 | VS | power_in | Analog supply pin; for the TMCS1108A4U the recommended operating supply is 4.5 V to 5.5 V (5 V nominal), with an absolute maximum of 6 V relative to GND. |
