TMCS1101A3UQDRQ1

Texas Instruments · Current Sensors · SOIC-8

TMCS1101A3UQDRQ1 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; the current polarity is positive when current flows into IN+, and VIN+ is limited to ±600 VPK relative to GND (pin 5).
2 IN+ input Input current positive pin, internally paired with pin 1 as a second IN+ terminal; the input voltage is limited to ±600 VPK relative to GND (pin 5).
3 IN- input Input current negative pin; the input voltage is limited to ±600 VPK relative to GND (pin 5).
4 IN- input Input current negative pin, internally paired with pin 3 as a second IN- terminal; the input voltage is limited to ±600 VPK relative to GND (pin 5).
5 GND power_in Analog ground reference for the device; the input voltages VIN+ and VIN- are specified relative to this pin.
6 NC unconnected No connect; the pin can tolerate a capacitive or resistive connection to GND or VS, and a short to GND is recommended where acceptable.
7 VOUT output Analog output voltage, with absolute maximum range GND - 0.3 V to (VS) + 0.3 V; the linear range is limited by swing to supply and ground.
8 VS power_in Analog power supply; for the TMCS1101A3B/U-Q1 variant the operating supply voltage is 3 V to 5.5 V (absolute maximum 6 V with respect to GND).
