TMCS1108A2UQDR 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 pin accepting input current flow into the isolated sensing path. |
| 2 | IN+ | input | Positive current input pin accepting input current flow into the isolated sensing path. |
| 3 | IN- | input | Negative current input pin providing return path for input current from the isolated sensing path. |
| 4 | IN- | input | Negative current input pin providing return path for input current from the isolated sensing path. |
| 5 | GND | power_in | Ground reference pin providing return path for the analog signal chain operating from 3V to 5.5V supply voltage. |
| 6 | NC | unconnected | No connection pin; can accept capacitive or resistive connections to GND or VS and is recommended to be shorted to GND if acceptable. |
| 7 | VOUT | output | Analog output voltage pin providing signal proportional to input current with 100mV/A sensitivity for TMCS1108A2U variant. |
| 8 | VS | power_in | Power supply pin requiring 3V to 5.5V operating voltage to power the signal chain and establish output reference. |
