+description: |
+  The ADT7462 is a temperature and voltage monitor and a PWM fan controller.
+
+  It can monitor temperature in up to three remote locations, as well as
+  its ambient temperature.
+  There are up to four PWM outputs to control fans.
+  The ADT7462 supports high frequency PWM for 4-wire fans and low frequency
+  PWM for 2-wire and 3-wire fans. Up to eight TACH inputs can be used to
+  measure the speed of 3-wire and 4-wire fans. There are up to 13 voltage
+  monitoring inputs, ranging from 12 V to 0.9 V.
+
+  Datasheet:
