Keep the high-current traces short and wide to the package pins; the Hall element is inside the IC, so the magnetic field it sees depends on the PCB copper geometry. A solid ground plane under the sensor helps shield it from stray fields. The surface-mount footprint matches standard SOIC-8 land patterns; no special pad geometry required. ## Supply and temperature range Operates from 3 V to 5.5 V, drawing a maximum of 6 mA. The -40 °C to 125 °C ambient range covers automotive under-hood and industrial motor-drive environments. The ratiometric output scales with the supply voltage, so if the ADC reference is also the sensor supply, the measurement stays ratiometric — no separate reference needed.","metaTitle":"TMCS1101A2UQDT Hall-Effect Current Sensor, 100mV/A, 8-SOIC","metaDescription":"TI TMCS1101A2UQDT ratiometric voltage-output Hall-effect current sensor. 100 mV/A sensitivity, 80 kHz bandwidth, unidirectional AC/DC sensing.
