TMCS1108A4UQDRQ1 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 | Positive input current pin; current flows through isolated conductor between IN+ and IN- pins for Hall effect measurement with ±120V maximum rating. |
| 2 | IN+ | input | Positive input current pin; current flows through isolated conductor between IN+ and IN- pins for Hall effect measurement with ±120V maximum rating. |
| 3 | IN- | input | Negative input current pin; current flows through isolated conductor between IN+ and IN- pins for Hall effect measurement with ±120V maximum rating. |
| 4 | IN- | input | Negative input current pin; current flows through isolated conductor between IN+ and IN- pins for Hall effect measurement with ±120V maximum rating. |
| 5 | GND | power_in | Analog ground reference for signal processing side; input voltage between IN+ and IN- pins must not exceed ±120V absolute maximum. |
| 6 | NC | unconnected | No connection; pin may be left open or connected to GND or VS with capacitive or resistive coupling without adverse effects. |
| 7 | VOUT | output | Analog output voltage proportional to input current at 400mV/A sensitivity with zero-current offset at 0.1×VS; output range approximately 0.1V to (VS-0.1V). |
| 8 | VS | power_in | Power supply input; recommended operating voltage 4.5V to 5.5V for A4U model; powers signal processing chain and output amplifier. |
