It measures bidirectional AC or DC current up to ±22.5 A and outputs a ratiometric voltage proportional to the sensed current, with a sensitivity of 100 mV/A.
The AEC-Q100 qualification and automotive temperature range mean this sensor is a standard production part, not a niche or sunset item — no reason to expect a short procurement window.
Yes, the TMCS1108A2BQDRQ1 is AEC-Q100 qualified, confirming its suitability for automotive applications.
The output is ratiometric voltage — the output voltage scales proportionally with the supply voltage and the sensed current.
