description: |

  The ADT7473, ADT7475, ADT7476, and ADT7490 are thermal monitors and multiple

  PWN fan controllers.

  They support monitoring and controlling up to four fans (the ADT7490 can only

  control up to three). They support reading a single on chip temperature

  sensor and two off chip temperature sensors (the ADT7490 additionally

  supports measuring up to three current external temperature sensors with

  series resistance cancellation (SRC)).
