Product details

Package and layout — 8-SOIC

The 8-SOIC (3.90 mm width) package carries the primary current through the leadframe — no external sense resistor. 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.

Frequently asked questions

What is the sensitivity of TMCS1101A2UQDT?

100 mV/A. At 5 A the output is 0.5 V above the zero-current reference; at 10 A it is 1.0 V. The output is ratiometric to the supply voltage.

Is TMCS1101A2UQDT unidirectional?

Yes, the polarization is unidirectional. The output voltage increases for current flowing in the forward direction and decreases below the zero-current reference for reverse current. It cannot output a negative voltage relative to ground.

What is the response time of TMCS1101A2UQDT?

6.5 µs typical. The bandwidth is 80 kHz. These numbers suit motor-drive current loops and switching-supply monitoring but not sub-microsecond fault detection.
