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.
