The NCT7201/NCT7202 is a Nuvoton Hardware Monitor IC, contains up to 12
14
+
voltage monitoring channels, with SMBus interface, and up to 4 sets SMBus
15
+
address selection by ADDR connection. It also provides ALERT# signal for
16
+
event notification and reset input RSTIN# to recover it from a fault
17
+
condition.
18
+
19
+
NCT7201 contains 8 voltage monitor inputs (VIN1~VIN8).
20
+
NCT7202 contains 12 voltage monitor inputs (VIN1~VIN12).
