Sensitivity is fixed at 100 mV/A. The part runs from a 3 V to 5.5 V supply and draws a maximum of 6 mA. ## AEC-Q100 Grade 1 — qualified, not just capable This part carries the Automotive, AEC-Q100 series designation, which means it has passed the full suite of AEC-Q100 stress tests — including high-temperature operating life, temperature cycling, and ESD — at the Grade 1 temperature range of -40°C to 125°C. For an OEM auditor reviewing a PPAP submission, that qualification is the difference between a signed-off BOM and a request for a deviation. The lifecycle status is Active; no NRND or last-time-buy notice is in effect. The part is ROHS3 compliant. ## Bandwidth and response time — what they mean for the loop The 80 kHz bandwidth covers switching frequencies up to several hundred kHz with adequate attenuation, suitable for motor-drive phase current feedback and DC-DC converter output monitoring. The 6.5 µs response time defines how quickly the output settles after a step change in sensed current — fast enough for overcurrent detection thresholds in most automotive loads, but not intended for sub-microsecond fault latch circuits. ## Package and mounting Housed in an 8-SOIC package with a 3.90 mm body width, the TMCS1107A2UQDRQ1 is a surface-mount device that reflows on a standard lead-free profile. The 8-pin footprint keeps board area small; the single channel occupies one sense-resistor position on the PCB. ## Linearity and output type Linearity is specified at ±0.5%, which means the output deviates from an ideal straight-line transfer function by no more than half a percent of full scale — tight enough for accurate current monitoring in battery-management and motor-control loops. The ratiometric voltage output scales proportionally with the supply voltage, so the zero-current and full-scale voltages track the ADC reference when both share the same rail.","metaTitle":"TMCS1107A2UQDRQ1 Hall Effect Current Sensor, 100 mV/A","metaDescription":"TI TMCS1107A2UQDRQ1 automotive Hall-effect current sensor, 100 mV/A sensitivity, ratiometric voltage output, 3-5.5V supply, -40 to 125°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Output":"Ratiometric, Voltage","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Frequency":"80kHz","Linearity":"±0.5%","Sensitivity":"100mV/A","Sensor Type":"Hall Effect","Polarization":"Unidirectional","For Measuring":"AC/DC","Mounting Type":"Surface Mount","Response Time":"6.5µs","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"1","Operating Temperature":"-40°C ~ 125°C (TA)","Current - Supply (Max)":"6mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.84","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.84000","currency":"USD"},{"qty":5,"price":"$4.27600","currency":"USD"},{"qty":10,"price":"$3.77600","currency":"USD"},{"qty":25,"price":"$3.06360","currency":"USD"},{"qty":50,"price":"$2.70760","currency":"USD"},{"qty":100,"price":"$2.63620","currency":"USD"},{"qty":500,"price":"$2.20876","currency":"USD"},{"qty":1000,"price":"$2.13750","currency":"USD"},{"qty":2500,"price":"$2.13750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e6e13883bae94232cebb120a6401aeea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the TMCS1107A2UQDRQ1 sensitivity 100 mV/A?","answer":"Yes, the sensitivity is fixed at 100 mV/A.
