0019 Description
0020 -----------
0021
0022 The LTC4151 is a High Voltage I2C Current and Voltage Monitor.
0023
0024
0025 Usage Notes
0026 -----------
0027
0028 This driver does not probe for LTC4151 devices, since there is no register
0029 which can be safely used to identify the chip. You will have to instantiate
0030 the devices explicitly.
0031
0032 Example: the following will load the driver for an LTC4151 at address 0x6f
0033 on I2C bus #0::
0034
0035 # modprobe ltc4151
0036 # echo ltc4151 0x6f > /sys/bus/i2c/devices/i2c-0/new_device

0042 Voltage readings provided by this driver are reported as obtained from the ADIN
0043 and VIN registers.
0044
0045 Current reading provided by this driver is reported as obtained from the Current
0046 Sense register. The reported value assumes that a 1 mOhm sense resistor is
0047 installed.
