TMCS1100A3QDR 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 | Positive input current pin; input current flows between IN+ and IN- pins (pins 1-2 and 3-4 form input current paths) |
| 2 | IN+ | input | Positive input current pin; input current flows between IN+ and IN- pins (pins 1-2 and 3-4 form input current paths) |
| 3 | IN- | input | Negative input current pin; input current flows between IN+ and IN- pins (pins 1-2 and 3-4 form input current paths) |
| 4 | IN- | input | Negative input current pin; input current flows between IN+ and IN- pins (pins 1-2 and 3-4 form input current paths) |
| 5 | GND | power_in | Analog ground reference for signal circuit; voltage range GND (0V) |
| 6 | VREF | power_in | Zero current output voltage reference input; externally supplied voltage from GND to VS (0V to VS) that sets VOUT at zero input current |
| 7 | VOUT | output | Analog output voltage proportional to input current; linear swing range 0.05V to VS−0.2V for TMCS1100A3 (200mV/A sensitivity) |
| 8 | VS | power_in | Analog power supply voltage; operating range 3V to 5.5V for TMCS1100A3 |
