It measures both AC and DC over a ±11.25 A range with a sensitivity of 200 mV/A and linearity of ±0.5%. Rated for -40°C to 125°C ambient and qualified to AEC-Q100, this part is intended for under-hood and chassis-domain automotive electronics, as well as industrial drives that specify automotive-grade components for extended temperature and reliability margins. ## Package and mounting Housed in an 8-SOIC (3.90 mm width) package, surface-mount. The Hall element is internal — no external magnetic core or shield required. The 6 mA max supply current keeps the self-heating low, so thermal derating on the PCB is minimal. Standard SOIC-8 footprint, no special layout beyond keeping the high-current traces short and wide to minimise IR drop that could couple into the sense path. ## Lifecycle and sourcing posture For a BOM line that needs an automotive-grade Hall sensor at this sensitivity and range, this part is a current-design-in candidate — no LTB risk.","metaTitle":"TMCS1107A3BQDT Hall Effect Current Sensor, ±11.25A, 200mV/A","metaDescription":"TI TMCS1107A3BQDT automotive-grade Hall current sensor, ±11.25A bidirectional, 200mV/A ratiometric output, 80kHz bandwidth, 8-SOIC.

The supply range of 3 V to 5.5 V includes 3.3 V directly. The output is ratiometric, so at 3.3 V supply the full-scale voltage scales proportionally — ensure the ADC reference tracks the supply or adjust the scaling in firmware."},{"question":"Can TMCS1107A3BQDT measure both AC and DC?","answer":"Yes.

The A3B variant shown here is the 200 mV/A option — the choice depends on the required full-scale output voltage for the ADC input range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TMCS1107A3BQDT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TMCS1107A3BQDT when reusing this data.
