14 | Description |
15 | ----------- |
16 | |
17 | The LTC4151 is a High Voltage I2C Current and Voltage Monitor. |

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 |

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. |
