Product details

What this Hall sensor brings to a 12V/24V automotive rail

The TMCS1107A2BQDRQ1 is a single-channel Hall-effect current sensor from Texas Instruments, rated for bidirectional AC/DC sensing up to ±22.5 A. Its ratiometric voltage output scales at 100 mV/A.

Supply and output — what the 3 V to 5.5 V rail means for your BOM

The sensor runs from a single 3 V to 5.5 V supply, drawing 6 mA max. The output is ratiometric to the supply. Bidirectional sensing means the output sits at half-supply at zero current.

Package and mounting — hand-solderable SOIC

The 8-SOIC package (3.90 mm body width) is a standard surface-mount footprint.

Lifecycle and sourcing — active, no LTB risk

TI lists the TMCS1107A2BQDRQ1 as Active. For a BOM freeze or a production ramp, this part is safe to qualify in.

Frequently asked questions

Is TMCS1107A2BQDRQ1 a direct replacement for TMCS1107A2BQD?

The TMCS1107A2BQDRQ1 is the Tape & Reel variant of the TMCS1107A2BQD (which ships in Tube). The die, package, and electrical specs are identical. If your assembly line is set up for reel-fed pick-and-place, the Q1 suffix is the correct ordering code.

Does TMCS1107A2BQDRQ1 support a 3.3V supply?

Yes. The supply range is 3 V to 5.5 V, so a 3.3 V rail is within spec. The output is ratiometric — at 3.3 V supply, zero-current output sits at 1.65 V, and full-scale ±22.5 A corresponds to approximately 0 V to 3.3 V swing.

Can TMCS1107A2BQDRQ1 measure AC current?

Yes. The sensor is specified for both AC and DC measurement. The bidirectional output responds to the instantaneous polarity of the current, so AC waveforms are reproduced at the output up to the 80 kHz bandwidth limit.

What is the sensitivity of TMCS1107A2BQDRQ1?

Sensitivity is 100 mV/A. A 1 A DC current produces a 100 mV change at the output relative to the zero-current level (VCC/2).
