What the 100mV/A sensitivity and 80kHz bandwidth mean for your BOM
The TMCS1107A2UQDR is a Texas Instruments Hall-effect current sensor that outputs a ratiometric voltage proportional to the sensed AC or DC current. The 80 kHz bandwidth and 6.5 µs response time mean this sensor tracks fast current transients — switching power supplies, motor phase currents, or solenoid drive pulses — without the phase lag of a slower sensor. The ±0.5% linearity holds the output error across the full measurement range, so the ADC reading maps to the actual current within half a percent.
Automotive temperature grade and supply flexibility
Single-channel unidirectional sensing with a ratiometric voltage output: the output voltage scales with the supply rail, so a 3.3 V ADC sees the same proportion of full-scale regardless of supply drift.
Package, footprint, and storage note
The reel is supplied in Tape & Reel (TR) or Cut Tape (CT); store the reels dry per MSL level (verify the moisture sensitivity label on the reel).
