description: |
  The NCT7201/NCT7202 is a Nuvoton Hardware Monitor IC, contains up to 12
  voltage monitoring channels, with SMBus interface, and up to 4 sets SMBus
  address selection by ADDR connection. It also provides ALERT# signal for
  event notification and reset input RSTIN# to recover it from a fault
  condition.
 
  NCT7201 contains 8 voltage monitor inputs (VIN1~VIN8).
  NCT7202 contains 12 voltage monitor inputs (VIN1~VIN12).
