| 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). |
