It provides a complete battery management solution with accurate capacity reporting and impedance tracking for portable and USB-powered applications.","working_principle":"The fuel gauge uses impedance tracking to measure battery impedance in real-time. Combined with voltage and current measurements, it calculates state-of-charge (SOC), state-of-health (SOH), and time-to-empty. The algorithm adapts to battery aging over the product lifetime.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>VIN<\/td><td>Input<\/td><td>Power input<\/td><\/tr><tr><td>VBAT<\/td><td>Battery<\/td><td>Battery connection<\/td><\/tr><tr><td>PGND<\/td><td>Ground<\/td><td>Power ground<\/td><\/tr><tr><td>SDA<\/td><td>I2C Data<\/td><td>Serial data<\/td><\/tr><tr><td>SCL<\/td><td>I2C Clock<\/td><td>Serial clock<\/td><\/tr><tr><td>CE<\/td><td>Chip Enable<\/td><td>Active high<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Smartphone USB-C fast charging system<\/li><li>Portable medical device power management<\/li><li>Industrial handheld battery fuel gauge<\/li><li>USB power bank charger plus boost<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Brand<\/th><th>Current<\/th><th>Notes<\/th><\/tr><tr><td>MCP73871T-2CCI-ML<\/td><td>Microchip<\/td><td>1A<\/td><td>USB optimized<\/td><\/tr><tr><td>MP2636GR-Z<\/td><td>MPS<\/td><td>3A<\/td><td>Charger plus boost<\/td><\/tr><tr><td>MP2762A-0000<\/td><td>MPS<\/td><td>3A<\/td><td>Switching charger<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/10119","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=10119"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/10119\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=10119"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=10119"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=10119"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=10119"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
