+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)).
