TMCS1101A4BQDR

Texas Instruments · Current Sensors · SOIC-8

TMCS1101A4BQDR 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 Isolated input current positive terminal; 30A continuous RMS at 25°C, ±5.75A linear measurement range at VS=5V.
2 IN+ input Isolated input current positive terminal; parallel path to pin 1 for current distribution.
3 IN- input Isolated input current negative return terminal; parallel connection to pin 4 completing the measurement loop.
4 IN- input Isolated input current negative return terminal; parallel to pin 3 for return path.
5 GND power_in Analog ground reference for the isolated low-voltage output signal chain.
6 NC unconnected No connection pin with 1MΩ impedance; GND ≤ VNC ≤ VS; can be capacitively or resistively connected, short to GND recommended.
7 VOUT output Analog output voltage proportional to input current at 400mV/A sensitivity; 0.5×VS zero-current offset, operating range GND+5mV to VS-0.02V, 80kHz bandwidth.
8 VS power_in Analog power supply voltage for output signal chain; operating range 4.5V to 5.5V for TMCS1101A4B variant.
