ADT7476A集成電路（IC）的熱管理規(guī)格書PDF中文資料

ADT7476A屬于集成電路（IC）的熱管理。由安森美半導(dǎo)體公司制造生產(chǎn)的ADT7476A熱管理熱管理 IC 是根據(jù)溫度控制電路電源的半導(dǎo)體器件。這些 IC 的功能包括風(fēng)扇控制、硬件監(jiān)控器、溫度監(jiān)控系統(tǒng)、熱監(jiān)控器、熱電偶放大器、熱電偶調(diào)節(jié)器和溫度計(jì)–溫控器。檢測(cè)溫度范圍為 -260℃ 至 +1800℃，輸出類型有 I2C、SMBus、低電平有效/高電平有效、模擬電壓、開漏、PWM、SPI、2 線串行和并行–串行。

The ADT7476A controller is a thermal monitor and multiple PWM fan controller for noise-sensitive or power-sensitive applications requiring active system cooling. The ADT7476A can drive a fan using either a low or high frequency drive signal and can monitor the temperature of up to two remote sensor diodes plus its own internal temperature. The part also measures and controls the speed of up to four fans, so the fans operate at the lowest possible speed for minimum acoustic noise.
