TMCS1101A2UQDRQ1

Texas Instruments · Current Sensors · SOIC-8

TMCS1101A2UQDRQ1 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, connected through the internal 1.8 mΩ conductor to IN-, with the input voltage rated at ±600 VPK relative to GND.
2 IN+ input Second positive input current pin, internally tied to pin 1 through the same conductor, with the input voltage rated at ±600 VPK relative to GND.
3 IN- input Negative input current pin, internally tied to pin 4 through the same conductor, with the input voltage rated at ±600 VPK relative to GND.
4 IN- input Second negative input current pin, internally tied to pin 3 through the same conductor, with the input voltage rated at ±600 VPK relative to GND.
5 GND power_in Analog ground reference for the device, to which the input voltage limits and the VS decoupling capacitor (0.1 µF, placed as close as possible) are referenced.
6 NC unconnected No internal connection; the pin can tolerate capacitive or resistive connections to GND or VS, the datasheet recommends shorting it to GND where acceptable, and its input impedance is 1 MΩ for GND < VNC < VS.
7 VOUT output Analog output voltage that is proportional to the input current, swinging to within 0.1 V of VS and 10 mV of GND with a 10 kΩ load, and tolerating a maximum capacitive load of 1 nF without sustained oscillation.
8 VS power_in Analog supply pin operating from 3 V to 5.5 V, with an absolute maximum of 6 V relative to GND, and requiring a low-ESR 0.1 µF decoupling capacitor to GND.
