The device supports 2 independent PWM fan control outputs, a remote diode temperature sensor input for direct CPU\/GPU die temperature measurement, and an internal temperature sensor. Fan fault detection identifies stalled, underspeed, or overspeed conditions and generates an interrupt. The SMBus\/I2C interface allows system management software to monitor and override fan operation. The AEE suffix denotes QSOP-16 package and + indicates lead-free finish.","working_principle":"The MAX31760AEE+ operates as a precision fan-speed controller. (1) The device measures temperature using either the internal sensor or a remote thermal diode (typically on the CPU or GPU die). The remote diode measurement uses a switched-current technique that compares the forward voltage drop at two different bias currents to determine the diode temperature with +\/-1C accuracy. (2) The nonvolatile lookup table (LUT) maps temperature ranges to PWM duty cycles. When the measured temperature falls within a LUT entry range, the corresponding PWM duty cycle is automatically applied to the fan output. This autonomous operation continues without host intervention, reducing system management overhead. (3) The 2 PWM outputs are independently programmable with 8-bit duty cycle resolution (0.4% steps). The PWM frequency is configurable from 10Hz to 100kHz to match different fan types. Fan fault detection monitors the TACH input from each fan and triggers an interrupt if the fan speed deviates from the expected range, indicating a stalled or failing fan.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>SCL<\/td><td>SMBus\/I2C clock<\/td><\/tr><tr><td>2<\/td><td>SDA<\/td><td>SMBus\/I2C data<\/td><\/tr><tr><td>3<\/td><td>FAN1<\/td><td>PWM output for fan 1<\/td><\/tr><tr><td>4<\/td><td>TACH1<\/td><td>Tachometer input from fan 1<\/td><\/tr><tr><td>5<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>6<\/td><td>FAN2<\/td><td>PWM output for fan 2<\/td><\/tr><tr><td>7<\/td><td>TACH2<\/td><td>Tachometer input from fan 2<\/td><\/tr><tr><td>8<\/td><td>VDD<\/td><td>3.3V power supply<\/td><\/tr><tr><td>9<\/td><td>D-<\/td><td>Remote diode cathode<\/td><\/tr><tr><td>10<\/td><td>D+<\/td><td>Remote diode anode<\/td><\/tr><tr><td>11-16<\/td><td>Misc<\/td><td>INT, ADDR, NC, test pins<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Server and workstation fan control with NVRAM LUT for autonomous operation<\/li><li>Telecom equipment thermal management with dual-fan PWM control<\/li><li>Desktop PC CPU\/GPU fan control with remote diode temperature sensing<\/li><li>Industrial rack cooling management with fan fault detection<\/li><li>Storage system fan speed regulation with SMBus\/I2C interface<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>MAX31760AEE+T<\/td><td>ADI<\/td><td>Same, tape and reel packaging<\/td><\/tr><tr><td>MAX6639MEE+T<\/td><td>ADI<\/td><td>2-fan, 2-temp, similar function<\/td><\/tr><tr><td>ADM1032ARQZ-REEL7<\/td><td>ADI<\/td><td>Remote temp, no fan control<\/td><\/tr><tr><td>NCT7802Y<\/td><td>Nuvoton<\/td><td>Multi-fan, HWM, QFN-24<\/td><\/tr><tr><td>EMC2305<\/td><td>Microchip<\/td><td>5-fan controller, I2C, QFN<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7534","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=7534"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7534\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=7534"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=7534"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=7534"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=7534"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
