TMCS1100A1QDR
Texas Instruments · Current Sensors · SOIC-8
TMCS1100A1QDR 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 flowing into IN+ is defined as positive, and the recommended input voltage on IN+ and IN- is -600 to 600 VPK relative to GND (pin 5). |
| 2 | IN+ | input | Second positive input current pin, internally tied to pin 1 through the 1.8 mΩ conductor; the recommended input voltage is -600 to 600 VPK relative to GND (pin 5). |
| 3 | IN- | input | Negative input current pin; the recommended input voltage is -600 to 600 VPK relative to GND (pin 5), and it is galvanically isolated from the low-voltage side (pins 5 to 8). |
| 4 | IN- | input | Second negative input current pin, internally tied to pin 3; the recommended input voltage is -600 to 600 VPK relative to GND (pin 5). |
| 5 | GND | power_in | Ground reference for the low-voltage side; the absolute maximum rating for VS, VREF and VOUT is referenced to GND, and the operating range is GND-0.3 V to VS + 0.3 V for the analog pins. |
| 6 | VREF | power_in | External zero-current output voltage reference; it sets VOUT at zero input current and must stay within GND - 0.3 V to VS + 0.3 V (absolute maximum), with source impedance kept below the limit given in the electrical characteristics table. |
| 7 | VOUT | output | Analog output voltage proportional to the input current; the linear output swing is limited to roughly GND and VS, and the absolute maximum range is GND - 0.3 V to VS + 0.3 V. |
| 8 | VS | power_in | Low-voltage supply pin; the operating supply is 3 V to 5.5 V for TMCS1100A1 to A3 and 4.5 V to 5.5 V for TMCS1100A4, with an absolute maximum of 6 V (GND - 0.3 V to 6 V), and a 0.1 µF low-ESR decoupling capacitor is recommended close to the pin. |
