TMCS1107A3BQDR 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 pin, part of isolated current sensing path |
| 2 | IN+ | input | Input current positive pin, part of isolated current sensing path |
| 3 | IN- | input | Input current negative pin, part of isolated current sensing path |
| 4 | IN- | input | Input current negative pin, part of isolated current sensing path |
| 5 | GND | power_in | Analog ground reference |
| 6 | NC | unconnected | No connection; pin can withstand capacitive or resistive connection to GND or VS, recommended to short to GND |
| 7 | VOUT | output | Analog output voltage with 200mV/A sensitivity for A3B variant |
| 8 | VS | power_in | Power supply voltage, 3V to 5.5V operating range |
