| Description |
| ----------- |
| |
| The LTC4151 is a High Voltage I2C Current and Voltage Monitor. |
| |
| |
| Usage Notes |
| ----------- |
| |
| This driver does not probe for LTC4151 devices, since there is no register |
| which can be safely used to identify the chip. You will have to instantiate |
| the devices explicitly. |
| |
| Example: the following will load the driver for an LTC4151 at address 0x6f |
| on I2C bus #0: |
| # modprobe ltc4151 |
| # echo ltc4151 0x6f > /sys/bus/i2c/devices/i2c-0/new_device |
| |

| ------------- |
| |
| Voltage readings provided by this driver are reported as obtained from the ADIN |
| and VIN registers. |
| |
| Current reading provided by this driver is reported as obtained from the Current |
| Sense register. The reported value assumes that a 1 mOhm sense resistor is |
| installed. |
