High-side power-line monitoring is especially useful in battery-powered systems since it does not interfere with the ground paths of the battery chargers or monitors often found in “smart” batteries.\u003cbr\u003e\u003cbr\u003eThe MAX471 has an internal 35mΩ current-sense resistor and measures battery currents up to ±3A. For applications requiring higher current or increased flexibility, the MAX472 functions with external sense and gain-setting resistors. Both devices have a current output that can be converted to a ground-referred voltage with a single resistor, allowing a wide range of battery voltages and currents.\u003cbr\u003e\u003cbr\u003eAn open-collector SIGN output indicates current-flow direction, so the user can monitor whether a battery is being charged or discharged. Both devices operate from 3V to 36V, draw less than 100µA over temperature, and include an 18µA max shutdown mode.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eItem Type: Current Sensor\u003c\/li\u003e\n\u003cli\u003eOperating Voltage (V): 3 to 36\u003c\/li\u003e\n\u003cli\u003eOperating Current (A): +\/- 3A\u003c\/li\u003e\n\u003cli\u003eSensor: MAX471\u003c\/li\u003e\n\u003cli\u003eSensor Outputs: 1V \/ Amp\u003c\/li\u003e\n\u003cli\u003eLength (mm): 20\u003c\/li\u003e\n\u003cli\u003eWidth (mm): 18\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eComplete High-Side Current Sensing\u003c\/li\u003e\n\u003cli\u003ePrecision Internal Sense Resistor (MAX471)\u003c\/li\u003e\n\u003cli\u003e2% Accuracy Over Temperature\u003c\/li\u003e\n\u003cli\u003eMonitors Both Charge and Discharge\u003c\/li\u003e\n\u003cli\u003e3A Sense Capability with Internal Sense Resistor (MAX471)\u003c\/li\u003e\n\u003cli\u003eHigher Current-Sense Capability with External Sense Resistor (MAX472)\u003c\/li\u003e\n\u003cli\u003e100µA Max Supply Current\u003c\/li\u003e\n\u003cli\u003e18µA Max Shutdown Mode\u003c\/li\u003e\n\u003cli\u003e3V to 36V Supply Operation\u003c\/li\u003e\n\u003cli\u003e8-Pin DIP\/SO Packages\u003c\/li\u003e\n\u003cli\u003eCustomization: Suitable for electronic projects\u003c\/li\u003e\n\u003cli\u003eApplication: Current measurement in circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch2 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003eApplications :\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Monitoring Systems\u003c\/strong\u003e – Measures charge and discharge currents in lithium-ion and lead-acid batteries.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply Monitoring\u003c\/strong\u003e – Ensures stable current flow in DC power systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Current Sensing\u003c\/strong\u003e – Tracks motor performance and prevents overcurrent damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolar Power Management\u003c\/strong\u003e – Monitors solar panel output for optimized energy efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIoT and Embedded Systems\u003c\/strong\u003e – Integrates into microcontroller-based projects for real-time current measurement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eL x W (mm): 20.3 x 19.5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003e1 x Unsoldered GY-471 3A Range MAX471 Current Sensor Module\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":44350008295676,"sku":"KG952","price":269.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/gy-471-max471-3a-range-current-sensor-module-3.jpg?v=1740730873","url":"https:\/\/kitsguru.com\/es\/products\/gy-471-max471-3a-range-current-sensor-module","provider":"KitsGuru","version":"1.0","type":"link"}
