| 14 | Description |
| 15 | ----------- |
| 16 | |
| 17 | The LTC4151 is a High Voltage I2C Current and Voltage Monitor. |
| 18 | |
| 19 | |
| 20 | Usage Notes |
| 21 | ----------- |
| 22 | |
| 23 | This driver does not probe for LTC4151 devices, since there is no register |
| 24 | which can be safely used to identify the chip. You will have to instantiate |
| 25 | the devices explicitly. |
| 26 | |
| 27 | Example: the following will load the driver for an LTC4151 at address 0x6f |
| 28 | on I2C bus #0: |
| 29 | # modprobe ltc4151 |
| 30 | # echo ltc4151 0x6f > /sys/bus/i2c/devices/i2c-0/new_device |

| 33 | Sysfs entries |
| 34 | ------------- |
| 35 | |
| 36 | Voltage readings provided by this driver are reported as obtained from the ADIN |
| 37 | and VIN registers. |
| 38 | |
| 39 | Current reading provided by this driver is reported as obtained from the Current |
| 40 | Sense register. The reported value assumes that a 1 mOhm sense resistor is |
| 41 | installed. |
