TMCS1101A4BQDR 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 | Isolated input current positive terminal; 30A continuous RMS at 25°C, ±5.75A linear measurement range at VS=5V. |
| 2 | IN+ | input | Isolated input current positive terminal; parallel path to pin 1 for current distribution. |
| 3 | IN- | input | Isolated input current negative return terminal; parallel connection to pin 4 completing the measurement loop. |
| 4 | IN- | input | Isolated input current negative return terminal; parallel to pin 3 for return path. |
| 5 | GND | power_in | Analog ground reference for the isolated low-voltage output signal chain. |
| 6 | NC | unconnected | No connection pin with 1MΩ impedance; GND ≤ VNC ≤ VS; can be capacitively or resistively connected, short to GND recommended. |
| 7 | VOUT | output | Analog output voltage proportional to input current at 400mV/A sensitivity; 0.5×VS zero-current offset, operating range GND+5mV to VS-0.02V, 80kHz bandwidth. |
| 8 | VS | power_in | Analog power supply voltage for output signal chain; operating range 4.5V to 5.5V for TMCS1101A4B variant. |
