TMCS1107A1BQDRQ1 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 pin; current flowing into the positive input pin is treated as positive polarity, and VIN+ (relative to GND) is recommended within -420 V to 420 VPK. |
| 2 | IN+ | input | Input current positive pin (second IN+ pin, internally the same node as pin 1); current flowing into the positive input pin is treated as positive polarity, and VIN+ (relative to GND) is recommended within -420 V to 420 VPK. |
| 3 | IN- | input | Input current negative pin; the input current flows from IN+ through the internal 1.8 mΩ lead-frame conductor to IN-, and VIN- (relative to GND) is recommended within -420 V to 420 VPK. |
| 4 | IN- | input | Input current negative pin (second IN- pin, internally the same node as pin 3); the input current flows from IN+ through the internal 1.8 mΩ lead-frame conductor to IN-, and VIN- (relative to GND) is recommended within -420 V to 420 VPK. |
| 5 | GND | power_in | Analog ground for the low-voltage side; the input voltage ratings are referenced to this pin. |
| 6 | NC | unconnected | No internal connection; the pin can withstand capacitive or resistive connection to GND or VS, and shorting it to GND is recommended where acceptable, with an absolute maximum range of GND - 0.3 V to (VS) + 0.3 V. |
| 7 | VOUT | output | Analog output voltage proportional to input current; with RL = 10 kΩ to GND the output swings to within VS - 0.1 V and GND + 10 mV, and the maximum capacitive load is 1 nF without sustained oscillation. |
| 8 | VS | power_in | Analog supply for the low-voltage side; the operating supply range is 3 V to 5.5 V for the TMCS1107A1B/U-Q1 variant (absolute maximum 6 V). |
