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).
