Product details

Automotive-grade current sense in an 8-SOIC

The Texas Instruments TMCS1108A2BQDRQ1 is an automotive-qualified Hall-effect current sensor in an 8-SOIC surface-mount package. 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. Rated for the full -40°C to 125°C operating temperature range and AEC-Q100 qualified, this part is designed for under-hood and chassis-domain current monitoring in electric power steering, DC-DC converters, motor-phase current sensing, and battery-management systems.

Lifecycle and sourcing

The TMCS1108A2BQDRQ1 is listed as Active with ROHS3 compliance. 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.

Frequently asked questions

Is TMCS1108A2BQDRQ1 AEC-Q100 qualified?

Yes, the TMCS1108A2BQDRQ1 is AEC-Q100 qualified, confirming its suitability for automotive applications.

What is the output type of TMCS1108A2BQDRQ1?

The output is ratiometric voltage — the output voltage scales proportionally with the supply voltage and the sensed current.
