Sensitivity is 400 mV/A, bandwidth 80 kHz, response time 6.5 µs, operating from -40°C to 125°C. ## 6.5 µs response time — where it fits and where it doesn't The 80 kHz bandwidth and 6.5 µs response time suit motor-drive current loops. For higher switching frequencies, consider a higher-bandwidth isolated amplifier. ## Package and supply — what to plan for on the layout The 8-SOIC package (3.90 mm body width) uses a standard footprint. Supply range is 4.5 V to 5.5 V; maximum supply current is 6 mA. ## Unidirectional — not a bidirectional replacement This sensor measures current in one polarity only. For bidirectional sensing, use a bidirectional Hall sensor.","metaTitle":"TMCS1101A4UQDR Hall Effect Current Sensor, 400mV/A, 80kHz","metaDescription":"TI TMCS1101A4UQDR unidirectional Hall-effect current sensor, ratiometric voltage output, 400mV/A sensitivity, 80kHz bandwidth, -40 to 125°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Output":"Ratiometric, Voltage","Package":"Tape & Reel (TR); Cut Tape (CT)","Frequency":"80kHz","Linearity":"±0.05%","Sensitivity":"400mV/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":"4.5V ~ 5.5V","Number of Channels":"1","Operating Temperature":"-40°C ~ 125°C (TA)","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":"$2.11570","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/833b84666bf77368ec9e33c039b970e8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the sensitivity of TMCS1101A4UQDR?","answer":"The sensitivity is 400 mV/A, meaning the output voltage increases by 400 mV for each ampere of sensed current."},{"question":"Is TMCS1101A4UQDR unidirectional or bidirectional?","answer":"It is unidirectional — it measures current in one polarity only.
