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).
