+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)).
