It measures both AC and DC current bidirectionally up to 5.75 A, with a sensitivity of 400 mV/A and a bandwidth of 80 kHz. The ±0.5% accuracy and ±0.05% linearity make it suitable for motor-drive phase monitoring, power-supply output sensing, and battery-charger current loops where galvanic isolation is needed without a separate isolator. The 8-SOIC package and surface-mount footprint fit standard pick-and-place assembly, and the -40°C to 125°C operating range covers industrial enclosures and under-hood automotive environments. ## Supply and output — what the ratings mean for your BOM The sensor runs on a single 4.5 V to 5.5 V supply. Maximum supply draw is 6 mA. ## Bandwidth and response time — what they buy you The 80 kHz bandwidth covers the switching frequency of most motor drives and power converters, so you see the ripple waveform, not just the DC average. The 6.5 µs response time means the output settles within one or two PWM cycles — fast enough for overcurrent detection in a drive's firmware loop, but not fast enough for a hardware trip on a sub-microsecond fault. If you need a hardwired desaturation or fast-trip comparator, you'd add an external comparator ahead of this sensor's output. ## Package and mounting The 8-SOIC package (3.90 mm body width) is a standard surface-mount footprint that reflows on a normal lead-free profile. The supplier device package is 8-SOIC, same as the case code. No special clearance or slot in the PCB is needed — the Hall-effect die inside the package provides isolation through the mould compound, not through an air gap. ## Lifecycle and sourcing The TMCS1101A4BQDR is listed as Active with ROHS3 compliance.","metaTitle":"TMCS1101A4BQDR Hall Effect Current Sensor, 5.75A, 80kHz","metaDescription":"TI TMCS1101A4BQDR precision isolated Hall-effect current sensor: ±0.5% accuracy, 400 mV/A sensitivity, ratiometric voltage output, 4.5-5.5V supply, -40 to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Output":"Ratiometric, Voltage","Package":"Tape & Reel (TR); Cut Tape (CT)","Accuracy":"±0.5%","Frequency":"80kHz","Linearity":"±0.05%","Sensitivity":"400mV/A","Sensor Type":"Hall Effect","Polarization":"Bidirectional","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":"4.5V ~ 5.5V","Current - Sensing":"5.75A","Number of Channels":"1","Operating Temperature":"-40°C ~ 125°C","Current - Supply (Max)":"6mA","Supplier Device Package":"8-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.22","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.22000","currency":"USD"},{"qty":10,"price":"$3.78600","currency":"USD"},{"qty":25,"price":"$3.57920","currency":"USD"},{"qty":100,"price":"$3.10200","currency":"USD"},{"qty":250,"price":"$2.94288","currency":"USD"},{"qty":500,"price":"$2.64064","currency":"USD"},{"qty":1000,"price":"$2.22705","currency":"USD"},{"qty":2500,"price":"$1.47763","currency":"USD"},{"qty":5000,"price":"$1.42208","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cde3e91ada1110acf575070d0747e16e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output type of TMCS1101A4BQDR?","answer":"The output is ratiometric voltage — the output voltage scales proportionally with the supply voltage, so the zero-current offset and full-scale span track the 5 V rail."},{"question":"Is TMCS1101A4BQDR compatible with a 5V supply?","answer":"Yes, the supply voltage range is 4.5 V to 5.5 V, so a 5 V rail is right in the middle of the operating window."},{"question":"What package is TMCS1101A4BQDR available in?","answer":"It comes in an 8-SOIC package (3.90 mm body width), surface-mount, and is offered in Tape & Reel or Cut Tape options."},{"question":"How does TMCS1101A4BQDR compare to TMCS1101A3BQDR?","answer":"The TMCS1101A3BQDR is the same device with a different sensitivity — the A3 variant typically has a lower sensitivity (e.g., 200 mV/A) and a wider current range, while the A4BQDR offers 400 mV/A for finer resolution over a 5.75 A span.
