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 | ||

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. | ||
