TMCS1100A1QDRQ1

Current Sensors

Hall-effect current sensorIsolated current sensingAEC-Q10050 mV/ASOIC-8600 V working isolation

TMCS1100A1QDRQ1 is an automotive-qualified isolated Hall-effect current sensor with 50 mV/A sensitivity and a low-loss 1.8 mΩ current path.

Best for

  • Isolated motor-phase current sensing
  • Inverter and H-bridge current measurement
  • Automotive power monitoring

Avoid if

  • Applications requiring built-in stray-field rejection
  • Current levels exceeding the thermal safe operating area

Check before use

  • Confirm RMS and pulsed current limits for the actual PCB thermal environment.
  • Route high-current copper to minimize external magnetic-field error.
  • Use a low-impedance VREF source; the specified maximum source impedance is 5 kΩ.
