Description |
|
----------- |
|
|
|
The LTC4215 controller allows a board to be safely inserted and removed |
|
from a live backplane. |
|
|
|
|
|
Usage Notes |
|
----------- |
|
|
|
This driver does not probe for LTC4215 devices, due to the fact that some |
|
of the possible addresses are unfriendly to probing. You will have to |
|
instantiate the devices explicitly. |
|
|
|
Example: the following will load the driver for an LTC4215 at address 0x44 |
|
on I2C bus #0:: |
|
|
|
$ modprobe ltc4215 |
|
$ echo ltc4215 0x44 > /sys/bus/i2c/devices/i2c-0/new_device |
|
|
|
|
|
Sysfs entries |
|
------------- |
|
|
|
The LTC4215 has built-in limits for overvoltage, undervoltage, and |
|
undercurrent warnings. This makes it very likely that the reference |
|
circuit will be used. |
