TMCS1108A4BQDR 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; current flows through isolated internal 1.8mΩ conductor to produce magnetic field measured by Hall sensor. |
| 2 | IN+ | input | Input current positive terminal; current flows through isolated internal 1.8mΩ conductor to produce magnetic field measured by Hall sensor. |
| 3 | IN- | input | Input current negative terminal; completes isolated current path through internal 1.8mΩ conductor. |
| 4 | IN- | input | Input current negative terminal; completes isolated current path through internal 1.8mΩ conductor. |
| 5 | GND | power_in | Analog ground reference for signal chain and output amplifier. |
| 6 | NC | unconnected | No connection; pin may accept capacitive or resistive connection to GND or VS, with short to GND recommended. |
| 7 | VOUT | output | Analog output voltage proportional to input current at 400mV/A, output range 0.05V to VS-0.2V. |
| 8 | VS | power_in | Analog power supply operating range 4.5V to 5.5V for TMCS1108A4B variant. |
