It offers +\/-0.5C accuracy from 0C to 60C with 12-bit (0.0625C) temperature resolution. The device operates from 2.7V to 5.5V with only 45uA active current. Three address pins allow up to 8 devices on a single I2C bus. A programmable over-temperature alert (OS) output with configurable polarity and fault queue provides interrupt-driven thermal monitoring without continuous polling.","working_principle":"The TMP275AIDGKR uses a bandgap temperature-sensing element that generates a voltage proportional to absolute temperature (PTAT). This voltage is digitized by a delta-sigma ADC with 12-bit resolution (0.0625C per LSB). The result is stored in a read-only temperature register accessible via I2C. The OS (Over-temperature Shutdown\/Alert) comparator compares the measured temperature against programmable T_high and T_low thresholds stored in configuration registers. When the temperature exceeds T_high or drops below T_low, the OS pin asserts. The fault queue prevents false triggers from transient temperature spikes.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>SDA<\/td><td>I\/O<\/td><td>I2C serial data<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr><tr><td>3<\/td><td>ALERT<\/td><td>Output<\/td><td>Over-temperature alert<\/td><\/tr><tr><td>4<\/td><td>A0<\/td><td>Input<\/td><td>I2C address bit 0<\/td><\/tr><tr><td>5<\/td><td>A1<\/td><td>Input<\/td><td>I2C address bit 1<\/td><\/tr><tr><td>6<\/td><td>A2<\/td><td>Input<\/td><td>I2C address bit 2<\/td><\/tr><tr><td>7<\/td><td>V+<\/td><td>Power<\/td><td>Supply voltage (2.7-5.5V)<\/td><\/tr><tr><td>8<\/td><td>SCL<\/td><td>Input<\/td><td>I2C serial clock<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Server and storage system board-level thermal monitoring<\/li><li>Industrial process control temperature sensing<\/li><li>HVAC zone temperature measurement<\/li><li>Medical equipment thermal management and safety<\/li><li>Consumer electronics battery temperature monitoring<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>TMP275AIDR<\/td><td>8-SOIC<\/td><td>Same function, SOIC package<\/td><\/tr><tr><td>TI<\/td><td>TMP112AIDRLR<\/td><td>SOT-6<\/td><td>0.5C, I2C, smaller package<\/td><\/tr><tr><td>ADI<\/td><td>ADT7420UCPZ-RL7<\/td><td>16-LFCSP<\/td><td>0.25C accuracy upgrade<\/td><\/tr><tr><td>NXP<\/td><td>PCT2075DP<\/td><td>8-TSSOP<\/td><td>1C accuracy, I2C compatible<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/2736","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=2736"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/2736\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media\/2762"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=2736"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=2736"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=2736"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=2736"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
