TMCS1108A1UQDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN+ | input | Input current positive pin; isolated current measurement input path connected to IN+ reference. |
| 2 | IN+ | input | Input current positive pin; isolated current measurement input path connected to IN+ reference. |
| 3 | IN- | input | Input current negative pin; isolated current measurement input path connected to IN- reference. |
| 4 | IN- | input | Input current negative pin; isolated current measurement input path connected to IN- reference. |
| 5 | GND | power_in | Ground reference for the low-voltage signal chain side. |
| 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 proportional to input current; unidirectional zero-current output at 0.1×VS with 50mV/A sensitivity for A1U variant. |
| 8 | VS | power_in | Power supply for low-voltage signal chain side; operating voltage range 3V to 5.5V, quiescent current max 6mA across temperature. |
