Snyder <iws@ovro.caltech.edu> 17 18 19Description 20----------- 21 22The LTC4215 controller allows a board to be safely inserted and removed 23from a live backplane. 24 25 26Usage Notes 27----------- 28 29This driver does not probe for LTC4215 devices, due to the fact that some 30of the possible addresses are unfriendly to probing. You will have to 31instantiate the devices explicitly. 32 33Example: the following will load the driver for an LTC4215 at address 0x44 34on I2C bus #0:: 35 36 $ modprobe ltc4215 37 $ echo ltc4215 0x44 > /sys/bus/i2c/devices/i2c-0/new_device 38 39 40Sysfs entries 41------------- 42 43The LTC4215 has built-in limits for overvoltage, undervoltage, and 44undercurrent warnings. This makes it very likely that the reference 45circuit will be used. 46 47======================= ========================= 48in1_input input voltage 49in2_input output voltage 50 51in1_min_alarm input undervoltage alarm 52in1_max_alarm input overvoltage alarm 53 54curr1_input current 55curr1_max_alarm overcurrent alarm 56 57power1_input power usage 58power1_alarm power bad alarm 59======================= ========================= 60
