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).
