The digital result is available over the I2C bus. The OS output is a programmable thermostat that asserts when temperature exceeds the Tos threshold and de-asserts when it drops below the Thyst hysteresis level. It can operate in comparator mode (OS follows temperature) or interrupt mode (OS latches until cleared by reading).","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>SDA<\/td><td>I2C serial data (bidirectional)<\/td><\/tr><tr><td>2<\/td><td>SCL<\/td><td>I2C serial clock input<\/td><\/tr><tr><td>3<\/td><td>OS<\/td><td>Over-temperature shutdown output (open-drain)<\/td><\/tr><tr><td>4<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>5<\/td><td>A2<\/td><td>I2C address bit 2<\/td><\/tr><tr><td>6<\/td><td>A1<\/td><td>I2C address bit 1<\/td><\/tr><tr><td>7<\/td><td>A0<\/td><td>I2C address bit 0<\/td><\/tr><tr><td>8<\/td><td>V+<\/td><td>Power supply (2.8V-5.5V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>System thermal management and monitoring<\/li><li>Fan speed control based on temperature<\/li><li>PC and server temperature monitoring<\/li><li>Industrial process temperature sensing<\/li><li>Battery charger temperature protection<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Spec1<\/th><th>Spec2<\/th><\/tr><tr><td>LM75BDP<\/td><td>NXP<\/td><td>Same function<\/td><td>TSSOP-8 package<\/td><\/tr><tr><td>TMP102AIDRLR<\/td><td>TI<\/td><td>12-bit 0.0625C<\/td><td>SOT563<\/td><\/tr><tr><td>ADT75BRMZ<\/td><td>ADI<\/td><td>12-bit 0.0625C<\/td><td>MSOP-8<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9764","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=9764"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9764\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9764"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9764"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9764"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9764"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
